etal bar grating can be defined as a seriesof metal bars positioned vertically, placed

an equal distance apart and joined by crossmembers to form a rectangular or reticulinepattern. Typically manufactured from mildcarbon steel, 6000 series aluminum and 300series stainless steels, bar gratings are alsoavailable in specialty metal alloys to suit nearly any application.

BEARING BARS – The vertically positioned barsare designated as the bearing bars. These barsrange in size from 3/4" x 1/8" for lightpedestrian traffic to 7" x 1/2" for extremevehicular loads. Typically, the spacing of thebearing bars is indicated in sixteenths of aninch, measured from the center of one bar to thecenter of the adjacent bar. This center to centeror on center spacing ranges from 7/16" to19/16" (1-3/16") on standard gratingproducts. Standard gratingsare also available withwider spacings

providing even greater open area, butshould not be specified without consultingthe manufacturer. Heavy Duty gratingproducts are commonly manufactured withbearing bar spacings ranging from 15/16" to38/16" (2-3/8") on center.

CROSS BARS – The bars used to securethe position of the bearing bars arecommonly designated as the cross bars.Cross bar profiles vary according to themethod of assembly and material selected.As with bearing bars, cross bar spacing ismeasured as on center spacing. Thecustomary cross bar spacing is 4" on center.On special order, 2" on center and otherspecial spacings are also available.

INTRODUCTION

SWAGED PRESSURE LOCKEDCross bars are inserted intopre-punched holes in thebearing bars andhydraulically swaged to lockthe bars in place. Mosteffective for the manufactureof aluminum, stainless, andclose mesh gratings.

DOVETAIL PRESSURE LOCKEDAssembled by insertingpunched bearing and crossbars into an "eggcrate"configuration and deformingthe cross bars underhydraulic pressure. Excellentfor the manufacture ofarchitectural gratings.

RIVETED GRATINGBearing bars arepermanently riveted toreticulated cross bars toform our most rigid anddurable products. Extremelywell suited to absorb shockand impact loads from cartand dolley traffic.

SPAN

WIDTH

UNSUPPORTED SPAN

roper specification of bar gratings includes adetermination of load conditions, effective

unsupported clear span, flooring surface, trimand finish. Appropriate consideration of theseelements plus any features unique to theirparticular application will allow the specifyingauthority to select products that will provideyears of continuing service.

SPAN – In grating nomenclature, span servesa dual role in defining two significant features.First, unsupported span indicates the cleardistance between effective points of support forthe grating. Once the specifier has established thedesign load and acceptable deflection criteria,grating selection will be dictated by determiningthe maximum unsupported span and consultingthe load tables on the pages that follow. Secondly,span indicates the overall finished length of thegrating panels (parallel to the bearing bars) asthey are supplied to the customer.

WIDTH – The overall dimension of the gratingpanel measured perpendicular to the bearing barspan is designated as the panel width.Commonly manufactured and stocked in 24" and36" nominal widths, grating panels can easily besupplied in a variety of widths to suit the needsof any application. For non-stock widths, consultthe Panel Width Chart on page 17 of thiscatalog. Additionally, custom widths can be shopfabricated to hold any specific tolerance.

SERRATED SURFACE – The excellent drainageand self-cleaning characteristics of plain surfacegrating make it suitable for the majority ofapplications. In the presence of materials which

could cause the top surface of the bars to becomeslippery, the optional serrated surface should beconsidered. When serrated surfaces are specified,the bearing bar depth must be increased 1/4"greater than the sizes shown in the load tablesand selection guides to provide the equivalentstrength of non-serrated bars.

BANDING – To enhance architecturalappearance or to provide additional transversestiffness, the open ends of the grating panels canbe banded. This is achieved by welding a flatbar,similar in size to the bearing bars, to the cut endsof the grating panel. Banding can reduce impactstresses by transferring loads to adjacent bars thatare not directly subjected to service loads. Trimbanding should always be considered when thegrating panels are designed to be removable oneven an infrequent basis. Additionally, bandingshould always be specified when the ends of thebearing bars are unsupported or the grating isdesigned to service vehicular loads. Furtherbanding descriptions and welding standards canbe found on page 17 of this catalog.

FINISHES – Steel grating products are usuallyshipped with one of three standard finishes, baresteel, painted with one coat of the manufacturersred or black paint, or hot dip galvanized afterfabrication in accordance with ASTM Standard A-123. Aluminum products are commonly suppliedas mill finished, but are also available withoptional anodized finishes. Stainless steel productsas produced typically require secondary finishingsuch as chemical cleaning, abrasive blasting orelectro-polishing. All of our grating products can

additionally be supplied with specialty customfinishes such as enamel or epoxy coatings. Whenconsidering such finishes, careful evaluation of thespecified material and consultation with thecoating manufacturer is essential.

WELDED STEEL GRATING

hen selecting a bar grating product, consider Welded Steel Grating first. Usuallyour most economical products, they provide a comfortable walking surface

with nearly 80 percent open area. This, combined with the positive welded crossbar/bearing bar intersection, make these products our most popular. Manufacturedfrom ASTM A-1011 carbon steel, welded gratings are recommended for nearly allindustrial flooring applications.

To specify welded steel grating, first specify the type of grating from the adjacenttable. In the instance of standard welded grating, the "W" indicates the assembly ofthe grating shall be Welded construction, the "19" indicates that the bearing barsshall be 19/16's (1-3/16) inches on center, and the "4" indicates that the cross barsshall be spaced at 4 inches on center. Following selection of the type of grating,consult the load table below to select the appropriate bearing bar size for the loadsand spans to be serviced. Proper designation for standard welded grating with 1" x3/16" bearing bars is indicated 19W4 1" x 3/16".

luminum grating products are light in weight, resistant to atmospheric corrosion, non-sparking and offer an attractive appearance. These characteristics make aluminum grating

especially suitable for water and sewage treatment facilities, marine environments, foodprocessing and petro-chemical installations. Manufactured from 6061 and 6063 alloys, the mostpopular and economical method of assembly for aluminum gratings is pressure locking by theswaging process. This versatile manufacturing system allows us to offer three distinct profiles:Standard Rectangular Bar, Flush-Top Rectangular Bar and I-bar. Each profile is illustrated below.

To specify Indiana Gratings Swaged Aluminum Grating, the type of grating is indicated bydesignating one of the three profiles shown combined with the bearing bar/cross bar spacingsillustrated in the table. Following selection of the type of grating, consult the load table below toselect the appropriate bearing bar size for the loads and spans to be served.

PRESSURE LOCKED GRATING

MATER I A LSCommonly produced in ASTM A-1011 mild carbon steel, 6000 series aluminum and 300 series stainless

steels, Pressure Locked Gratings can also be manufactured in select specialty alloys. For assistance in selectingappropriate specialty alloys, please contact our sales department.

FABR I CAT I ONAll Indiana Gratings Pressure Locked Gratings are fabricated to size on a "per order" basis. To enhance

longevity, all products are manufactured with each outside cross bar/bearing bar intersection fillet welded inaccordance with NAAMM standards. Banding provides additional transverse stiffness and it is highlyrecommended that all Pressure Locked Gratings be specified with all cutouts and open ends banded (seebanding definition on page 3).

ISOMETRIC SWAGED INTERSECTION

SWAGED PRESSURE LOCKED GRAT I NGSPressure Locked Gratings manufactured by swaging are designated by the

profile "SG." These products are assembled by inserting hollow tube cross barsinto pre-punched holes in the bearing bars and then swaging the cross bars(similar to the aluminum gratings found on page 4). This permanently locks theentire cross bar/bearing bar intersection within the interior of the bearing bar.

DOVETA I L PRESSURE LOCKED GRAT I NGSPressure Locked Gratings manufactured with deep rectangular cross bars are

identified as dovetail pressure locked and are designated by the profile "DT."These products are assembled by pre-punching both the bearing bars and crossbars, aligning the bars in an egg-crate manner, and deforming the cross bar intothe dovetail slot in the bearing bar under intense hydraulic pressure.

CUSTOM BEAR ING BAR SPAC INGSThe Dovetail Pressure Locked method of manufacturing is particularly

flexible in that it allows for the production of gratings with custom bearing barspacings. Small quantities can easily be manufactured to suit the precise needsof most applications. To specify non-standard spacings, simply insert the desiredbearing bar center to center spacing (in sixteenths of one inch) in lieu of thestandard spacings shown in the table above (note that 4" and 2" cross barscenters should be maintained).

EXAMPLE: 8WH-4 FOR GRATING WITH BEARING BARS AT 1/2" ON CENTER

BEAR ING BAR S E L ECT I ON & LOAD TABLESThe bearing bar sizes offered for pressure locked gratings are common to

those in welded steel, swaged aluminum and stainless steel gratings. In that thesizes and spacings of the bearing bars are consistent with these products, theload tables are similarly interchangeable. Load tables for pressure locked gratingscan be found on the following pages:

ndiana Gratings offers two distinct types of Pressure Locked Gratings which are identified

by their method of assembly. Manufacturedwithout the introduction of heat or riveting,these gratings provide a finished product withattractive architectural lines. This pleasingappearance makes Pressure Locked Gratings ideal

candidates for architectural and ornamentalapplications such as grilles, screens and fences.Additionally, pressure locked methods ofmanufacturing allow for the production of closemesh gratings with minimal open area. PressureLocked Gratings with bearing bars spaced at11/16" and 7/16" on center conform with the

rigid spacing requirements of the Americanswith Disabilities Act (ADA). These products arecommonly installed at the entrance to publicbuildings where concerns of pedestrian trafficand high heeled shoes coincide with needs forventilation and drainage.

SERRATED SURFACEWhen the walking surface of bar gratings are subject to the accumulation of moisture or other slippery

substances, the optional serrated surface should be considered. Unlike rectangular mesh gratings where thebearing bars are typically constructed with the serrated surface, the standard method of manufacture forriveted gratings is to serrate the crimped cross member. When the grating is assembled, these crimp bars areallowed to project slightly above the top surface of the bearing bars to provide a superior unidirectional skidresistant surface. Environments particularly prone to unsafe walking conditions can be further specified as100% serrated where both the bearing bars and the crimp bars are provided with serrations.

MATER I A LS AND SPEC I F I CAT I ONSRiveted gratings are produced in carbon steel, 6000 series

aluminum and 300 series stainless steels. To specify RivetedGrating, first specify the type of grating from the table. In the instance of Standard Riveted Grating, The "18"indicates the method of assembly shall be riveted construction, the "18" indicates that the bearing bars shallbe spaced 18/16's (1-1/8) inches apart, and the "7" indicates that the rivets shall be spaced at 7" on center.Following selection of the type of grating, consult the load tables to select the appropriate bearing bar size forthe loads and spans to be served. To complete the specification, indicate which of the three materials isdesired for the application, carbon steel, aluminum or stainless steel.

B A N D I N GBecause heavy-duty gratings are commonly subjected to shock and impact loads

it is highly recommended that all open ends be banded. The welded band barhelps distribute impact loads and minimizes panel distortion when subjected torepetitious traffic patterns. Banding details can be found on page 3.

S E R R AT E D S U R FA C EOptional serrated bearing bars can be specified to enhance skid resistance.

B E A R I N G B A R S E L E C T I O NOnce the bar spacing is selected, the bearing bar size must be specified based

upon the anticipated load and the clear (unsupported) span to be served. The loadtables on pages 11-13 provide the maximum safe clear simple span for our mostpopular products based on the maximum traffic conditions defined. These tablesincorporate strict limitations where design deflection shall not exceed the lesser ofL/400 of the safe span indicated or 1/8 of one inch (.125).

C R O S S B A R S E L E C T I O NWhile bearing bar selection is critical for specifying a proper heavy-duty grating

for your application, the life-cycle of your installation will often be influenced byselection of the appropriate cross bar. The table below details alternative cross barsizes available. The sizes listed for Standard Loads are the standard twisted squareor round cross bars supplied by Indiana Gratings for a particular bearing bar size.These sizes have been selected to maximize manufacturing efficiency andeconomy. It is suggested that these sizes be specified when the grating is subject tointermittent traffic and only occasional full capacity loading.

The cross bars listed for Severe Loading are optional and will provide superiorrigidity and durability when gratings are subjected to intense, continuous orrepetitious traffic. Ideal for trench covers, highways and inlet grates, these crossbars enhance lateral stiffness thereby extending the service life of the grating.When specifying gratings with bearing bars centered at 1-3/8”, 1-7/8” or 2-3/8”,consideration of Severe Loading cross bars is highly recommended.

NOTE: IN THE EVENT THAT A CROSS BAR SIZE IS NOT SPECIFIED, THE CROSS BAR SHALL BESELECTED AT THE DISCRETION OF THE MANUFACTURER.

THE SIZES SHOWN ABOVE ARE LISTED AS MINIMUMS. TWISTED AND ROUND CROSS BARS ARE TYPICALLY INTERCHANGEABLE AND, UNLESS OTHERWISE SPECIFIED, MAY BE SUBSTITUTED AT THE DISCRETION OF THE MANUFACTURER. IN SUBSTITUTION, THECROSS SECTIONAL AREA OF THE ALTERNATIVE CROSS BAR SHALL EQUAL OR EXCEED THAT OF THE MINIMUM SIZE LISTED ABOVE.

elded Heavy-Duty products are designed to meet the need for gratings subject toheavy rolling and static loads such as highways, plant floors, loading docks,

inlet covers and airports. Since these conditions can range from light-duty forklifts tosemi-trucks and trailers carrying maximum allowable highway loads, heavy dutygratings are manufactured in a wide variety of bar sizes and spacings.

Indiana Gratings Heavy-Duty products are designed in accordance with currentAASHTO specifications for H-10 through H-20 loads. Automobile and forklift loads aresimilarly evaluated with loads calculated and distributed in accordance with thecriteria shown below. If your particular load conditions are not adequately addressedin the load criteria presented, please contact our engineering staff and we will bepleased to assist in the selection of a heavy-duty grating to satisfy your specific needs.

HEAVY DUTY GRATING


BRIDGE DECKING

ridge Decking is manufactured by cold-press riveting truss shaped recticuline bars to rectangular bearing

bars. The resulting product is an exceptionally durable heavyduty grating with superior stiffness and lateral stability.Bridge decking is often the preferred heavy duty grating forconcentrated or stress applications subject to impact andrepetitive loads. Common applications include bridge floors,highways, inlets, and airport trench drain covers.

mbed Frames cast into concrete floors and substructures serve a multitude of purposes that extend the effective life of your completed construction project. Frames form a permanent shield for concrete lead

edges and perimeters which are subject to cracking and chipping when left unprotected. During construction,these rigid 1/4" (minimum) thick steel frames expedite forming and provide a welded structure that assuresaccuracy in the concrete pour. Frames provide a uniform bearing surface for grates or covers, ofteneliminating rocking or irregular elevations experienced with covers installed on poured concrete. Inspecifying Indiana Gratings Embed Frames, you are specifying durability, accuracy and economy. (Nail holesare optional and may further expedite installation. If desired, size and location should be specified.)

rench Grating Systems by Indiana Gratings allow the specifier to combine any of the gratings illustrated abovewith any of the embed frames profiled on page 14. Gratings are available in Standard series for pedestrian loads

or Heavy Duty series for vehicular traffic. Unlike cast iron or molded trench products, this flexible system allows theuser to specify the exact clear opening ("S" dimension) desired. Because Indiana Gratings offers five distinct embedframe profiles, the user can select a frame to meet the exact edge condition desired. Bolting the grates to the frames isoptional and must be specified. All gratings are provided with plain surface (the optional serrated surface is alsoavailable when specified) and open ends are trench banded to maximize drain capacity. Unless otherwise noted, alltrench frames and grating are hot dip galvanized after fabrication in accordance with ASTM Specification A-123.

FASTENERS & BANDING

PANEL WIDTHS & LAYOUT

FASTENERSAll grating must be firmly fastened in place. Welding panels to the supporting

structure provides a superior, permanent installation. Gratings subject to removal can befastened with Weld Lugs which are shop welded between the bearing bars, or anchoredwith Saddle Clips. These fasteners, which are provided upon request, are punched with5/16" holes to receive 1/4" bolts or screws (bolts or screws supplied by others). In areaswhere welding or drilling is not permitted, "G" Clips can provide the fastening solution.These clips install on the top surface of the grating and create a friction connection withthe flange supporting the panel. The narrow spacing of close mesh gratings allows forcountersinking of the bearing bars and fastening with flat head screws.

PANEL W IDTHSGrating panels are manufactured in nominal 24" and 36" standard widths. When considering alternative widths, consult the table below to select widths that will

maintain consistent out to out spacing of the bearing bars. Widths specified which deviate from the table below can be fabricated utilizing side banding. In so doing,the outside bearing bar spacing on one side of the finished panel will deviate from the spacing throughout the rest of the panel.

PANEL LAYOUTAs stated above, stock grating panels are manufactured in 24" and 36"

nominal widths. Stock lengths (span) are 24'-0" for all sizes with most popularbearing bar sizes also available in 20'-0" lengths. These sizes allow for efficientlayout and waste minimization when they are fabricated to your exactspecification.

Unlike many competing products, individual grating panels do not requiresupports on all four sides of each cut piece. Bar grating panels only requiresupport perpendicular to the bearing bar span. There is no need to place supportsparallel to the bearing bars where adjacent panels are installed in succession.

SERRATED GRIP STRUT GRATING – StandardSerrated Surface offers excellent slipresistance wherever maximum safetyunderfoot is essential. Material meets anti-slip values set forth in Federal SpecificationRR-G-1602A.

NON-SERRATED GRIP STRUT GRATING – Forall-purpose use where a high degree of slipresistance is required plus a smoothertexture and design. Product is non-stockand subject to extended lead time.

STANDARD GRIP STRUT GRATING PLANKS – Available inmaterials and sizes to meet most load/span requirements.May be used as is or banded, cut, welded, or punched tosuit requirements.

Tested by an independent laboratory for slip resistanceaccording to standards and methods established byFederal Specification RR-G-1602D, GRIP STRUT® SafetyGrating proved its superiority by exceeding allrequirements of this specification.

The standards were exacting – five shoe sole materialstested in three directions under five conditions: dry,greasy, muddy, soapy and icy. GRIP STRUT® Safety Grating

tested 10% to 180% more slip-resistant than similarmaterials, depending on shoe materials andsurface conditions.

Fewer accidents, with resultant lower insurance costsand reduced workman’s compensation losses, should bethe logical reason for specifying GRIP STRUT® SafetyGrating for walking-working surfaces and stair treads.

Values determined in accordance with standards for

slip-resistance established by Federal Specification RR-G-1602D. The values indicated are an average of valuesobtained for five sole materials (leather, boot rubber, shoerubber, Neolite and Hypalon) tested in three directions(longitudinally, transversely and diagonally) for thesurface conditions noted. Values are in pounds of forcenecessary to move a 175 lb. load one inch across thesurface of grating.

GRIP STRUT¤ SAFETY GRATING

GRIP STRUT® Safety Grating, determine load, clear span anddeflection requirements. Having this information, select from loadtable the appropriate plank to meet job requirements.

Example: Clear span of 4’-O”, concentrated loadrequirement of 300 Ib. at 0.25” max. deflection. Select fromthe tables following:

For eight-diamond 18-3/4” wide, 2-1/2” channel, 12-ga. steelwhich carries a load of 416 Ib. at a 0.18” deflection. This is one sizeto do the job. Other sizes will carry more load if necessary. Formore economical selection, choose the greatest width that willsupport the load consistent with job requirements and choosedeeper channels rather than heavier steel gauges.

GRIP STRUT® Safety Grating will generally carry the sameconcentrated load, tabulated in Ib. at mid-span, for a given span,material gauge and channel height, regardless of width. (See “Howload tables were prepared” described below.) The uniform loadtables are tabulated in lb. sq. ft., which accounts for the differencein load capacity shown for various widths. Deflection is in inches.

HOW LOAD TABLES WERE PREPARED – The values shown in thefollowing tables are based on actual load tests conducted by anindependent laboratory. The tables have been prepared inaccordance with the provisions of the AISI Specification for theDesign of Cold-Formed Steel Structural Members, 1968 edition. Toensure the safety of the tabulated loads, two aspects of GRIPSTRUT® Grating strength must be considered.

The first consideration is transverse bending in the gratingsurface, which is referred to as strut flexure. This occurs when the

grating is loaded with either a uniform load or a mid-widthconcentrated load, and the struts (grating surface) deflect relativeto the side channels. To determine the allowable strut loads,samples of each grating material and thickness were tested for eachplank width. (See Fig. 1, below) The data resulting from these testswas used to prepare strut loading tables, which give allowableloads and deflections considering strut flexure only. Theseallowable strut loads, along with the results of additional testsperformed on 8- and 10-Diamond grating, have been incorporatedin the load tables on page 22.

The second aspect of GRIP STRUT Grating strength is channelflexure. This occurs when the channels at mid-span of the plankdeflect relative to support points. To verify the performance of theside channels, samples were loaded with concentrated and uniformloads at different spans (See Figs. 2 and 3). To approximate themost severe condition, there were no attachments between thechannels and the supports. In cases where spans are shorter,channels deeper and planks wider, strut flexure becomesmore critical.

3-, 4- AND 5-DIAMOND ALLOWABLE LOAD AND DEFLECTION TABLES –Since 2-through 5-Diamond planks are relatively narrow (less than1 ft. wide), it can be assumed that both side channels effectivelysupport the concentrated load and that the grating surfacedeflection is negligible. Based upon these assumptions, values inthe following load tables for 2- through 5-Diamond have beendetermined.

ALLOWABLE UNIFORM LOAD (U) – Values indicated in the rowsadjacent to “U” are the lowest of the (1) maximum allowableuniform loads considering channel flexure and (2) maximumgrating surface flexure.

DEFLECTION CORRESPONDING TO “U” – Deflection values areindicated below the uniform loads and are the mid-span sidechannel deflections for the planks carrying the allowable uniformloads (Fig. 3).

ALLOWABLE CONCENTRATED LOAD (C) – Values indicated in the rowslabeled “C” are the lowest of the (1) maximum allowableconcentrated load considering channel flexure (Fig. 2), with bothchannels effective, and (2) the maximum allowable strut load (Cs)for a 1-ft. long sample (Fig. 1).

DEFLECTION CORRESPONDING TO “C” – Deflection values indicatedbelow “C” values in the tables are the mid-span, side channeldeflections produced when the allowable concentrated load isplaced at mid-span.

If grating surface deflection should be considered whenselecting a product to meet a particular specification, then thedeflection of the mid-width of the grating, relative to the sidechannels, can be calculated using both the data in the StrutLoading Tables and the Load Deflection Conversion formula below.

Load data based on yield strength of 33,000 psi for steel,23,000 psi for aluminum, 35,000 psi for Type 304 stainless steel,and 30,000 psi for Type 316L stainless steel.

HOW TO R EAD LOAD TABLES

LOAD /DE F L ECT I ON CONVERS I ON FORMULAS

In the elastic range, deflection is proportional to theapplied load for both uniform and concentrated loads. Thisrelationship can be used to determine the deflection thatany load which is less than the allowable load will produce.

8 & 10 DIAMOND LOAD TABLES

s width increases, grating strut flexure becomes much more important. Eight and 10-Diamond products are

wide enough to require a change in the assumptions used toprepare the 2-through 5-Diamond Product Selection/DesignTables. No longer will it be assumed that both side channelsare equally effective in supporting a concentrated load. Infact, to provide a high level of safety, one side channel willbe required to carry 100% of a concentrated load.

Also strut deflection for 8- and 10-Diamond productsmay be significant. The most critical case occurs when aconcentrated load is located at mid-span and mid-width. Todetermine how the struts perform under this loading, 3-ft.long samples of each material and thickness were tested. Forthese tests the side channels were continuously supportedand loads were applied using a 1-ft. long and 1-in. wide bar

placed parallel to the side channels at mid-width and at thelongitudinal center.

Results of these tests, included in the 8- and 10-DiamondProduct Design Tables, proved the performance of thesematerials when a concentrated load is applied at mid-spanand mid-width. If a concentrated load is to be applied at mid-width at the end of a plank, consult the strut loading table.

The following values have been tabulated for 8- and 10-Diamond grating:

ALLOWABLE UNIFORM LOAD (U) – Values are given in the rowslabeled “U” and are the lowest of the (1) maximum allowableuniform loads considering channel flexure, and (2) maximumgrating surface flexure.

DEFLECTION CORRESPONDING TO “U” – Deflection valuesappear in the rows labeled “D”, below the “U” values, and are

maximum deflections the allowable uniform loads wouldproduce. Maximum deflections will occur at mid-span andmid-width and will be the sum of side channel and gratingsurface deflections. (Fig. 3).

ALLOWABLE CONCENTRATED LOAD (C) – Values tabulated in therows labeled “C”, are the lowest of the (1) maximumallowable concentrated load considering side channel flexure(with one side channel supporting the entire load-Fig. 2), and(2) the maximum allowable strut flexure (Fig. 1).

DEFLECTION CORRESPONDING TO “C” – Deflection values areindicated below the “C” values in the table and aredeflections the allowable concentrated loads will produce atmid-span and at mid-width. The deflection is the sum of sidechannel and grating surface deflections.

STANDARD GRIP STRUT® FASTENERS

ll gratings must be firmly anchored in place. Welding planks to the supporting structure

provides a superior, permanent installation. In areaswhere welding is not practical, or for installations wherethe planks must be removable, the diamond anchors oranchor clamp assemblies illustrated below can providesuitable alternatives.

ROOFTOP WALKWAY SYSTEMS

oofs look durable – but in most cases they were never intended to be walked upon. As the volume

of rooftop equipment continues to expand, the wear andtear of mounting maintenance traffic can lead to leaks inroofing membranes and permanent roof replacement.

GRIP STRUT® Rooftop Walkways are a componentsystem of GRIP STRUT® Safety Gratings and varioussupport brackets, protective pads and hardwareconnectors. These components can be incorporated at thedesign stage of new roofs, or assembled to retro-fitexisting structures.

Unlike other products, this system is elevated todiscourage shortcuts and emphatically define the path toservice rooftop equipment such as HVAC units andtelecommunications transmission equipment. Safety isprovided by the slip resistance of GRIP STRUT® SafetyGrating, renowned for safety in all types of weather.

In addition to safety, GRIP STRUT® Rooftop Walkwaysprovide unsurpassed life-cycle economy. Roofs last longer,with fewer leaks, and owners save on direct maintenanceand re-roofing expenses.

PERF-0 GRIP® SAFETY GRATING

BOLT SEATS – PERF-O GRIP® Bolt Seatsprovide a secure anchor of the grating tostructural supports. The standard bolt seatfeatures oblong holes specifically designed toensure a vertical anchor (with a 3/8” bolt)even if the hole is off concentrically by as

much as 1/4”. PERF-O GRIP®

Double Bolt Seats areavailable tomaximize theattachmentlocation flexibility

by providingapproximately 2” of

longitudinal adjustment. Availablein mill-galvanized steel, aluminumand stainless steel. Hardware is not provided.

ERF-O GRIP® Grating’s unique surface of largedebossed holes and perforated buttons provides

maximum slip protection and performance underpractically all conditions and in every direction.

In addition to providing safety, the resilient surface ofPERF-O GRIP® Grating cushions the impact of foot-fallsthereby lessening worker fatigue and increasing efficiency.PERF-O GRIP® Grating is one of your best safety buys. Itcuts costs and helps improve plant productivity.

SAFE SURFACE – Grips soles securely - in all directions.Slip resistant PERF-O GRIP® Grating surfaces are ideal forinside or outside locations where mud, ice, snow, oil anddetergents can create hazardous walking conditions.

The circular openings (38% of surface area dependingon product size) are small enough to catch most fallingtools and other dangerous objects. But the self-cleaningopen design permits quick drainage of fluids, chips, greaseand mud while permitting ventilation and lighting flow.Ice accumulation shears easily under normal foot pressure.Open design allows convenient access for cleaning. PERF-O GRIP® is easily cleaned with brush, liquid or airspray if desired.

LONG LIFE – PERF-O GRIP® Grating’s high load capacityand long-life, high strength-to-weight performance isachieved through depth of section and structural design.Formed struts with integral side channels form a plankthat can support loads with minimum transverse andlongitudinal deflection. This sturdy construction providesthe advantages of heavy load-carrying capacity with

minimal deflection; rugged durability with longerlasting performance.

FAST INSTALLATION – Light, easy-to-handle planks makeinstallation simple and quick. They can be handled byone person. Most sections are rapidly bolted, clamped orwelded into place, easily field cut at virtually any angle, orfabricated to adapt to field conditions.

ECONOMICAL TO INSTALL AND USE – In addition to lowmaterial cost and nominal erection cost, PERF-O GRIP®

Grating also features long-lasting rust-resistant materialsand finishes. Standard mill-galvanized finish resistscorrosion to provide lasting surfaces. High-strengthaluminum, Type 316-2D and Type 304-2D stainless steelsare available to provide maximum corrosion resistance.Black unpainted steel is available for those installationsrequiring paint. Lightweight but brawny panels permitsubstantial reduction in structural steel requirements.

VERSATILE IN APPLICATION – A variety of standard widthsand channel heights are available as well as numerousnon-standard shapes and sizes to meet almost anyrequirements of strength, size, durability, weight, finish,appearance and application.

PERF-O GRIP® Grating combines safety and durabilitywith ease of fabrication and versatility. One-piececonstruction minimizes the need for field fabrication.Special shapes and forming can be accomplished to suitunusual requirements.

PERF-O® GRIP Grating may be hot dipped galvanizedafter fabrication, anodized, plated, plastic-coated or

otherwise finished to suit job requirements. StandardPERF-O GRIP® Plank is available in materials and sizes tomeet most load/span requirements. May be used as is, orbanded, cut, welded or notched to suit requirements.

ALLOWABLE LOADS AND DEFLECTIONS: U – UNIFORM LOAD (LB./FT.), C – CONCENTRATED LOAD (LB.), D – DEFLECTION (IN.). SPANS TO THE LEFT OF HEAVY LINE PRODUCE A DEFLECTION OF 1/4” OR LESS UNDER AUNIFORM LOAD OF 100 LBS. PER SQUARE FOOT. FOR PERF-O GRIP PRODUCT WIDTHS GREATER THAN 12”, USE OF GRATING SPLICE KIT IS RECOMMENDED TO MECHANICALLY JOIN BUTT ENDS OF LENGTH.


RATE-LOCK® Grating is an easy-to-install system of interlocking grating planks, treads and accessories

that provides safe, sturdy footing for mezzanine floors,platforms, walkways and other applications where non-slip performance is required. Hundreds of sole-grippingdimples insure a safe surface in all kinds of of weather andenvironments. The grating is available textured for saferworking surfaces, non-textured for wheeled traffic orrack decking.

COST-SAVING DESIGN IMPROVES LOADING PERFORMANCE –The unique design of GRATE-LOCK Grating gives youmore design options – at less cost than other gratingsystems. Increased load performance (see charts) has beenachieved through interlocking planks, stronger rungdesign and an expanded selection of leg heights andmaterial gauges. GRATE-LOCK Grating lets you specifylighter gauge steel for substantial material saving.

MORE SIZES, GAUGES – GRATE-LOCK Grating provides

the broadest line products of any manufacturer. Availablein three plank widths, four plank heights, three gaugesand lengths to 24’. Interlocking sections provide thestrength you need for extra-wide designs.

FULL LINE OF ACCESSORIES, TOO – Our line includeskickplates, hold-down clamps, attachment hardware andstair treads for complete job design.

FAST BOLT-TOGETHER ASSEMBLY – Save time in the fieldwith GRATE-LOCK bolt-together slotted assemblies.Kickplates and plank sections are prepunched. Foradditional ease, planks can be straight, curved or anglecut with hand tools.

SPECIFY GRATE-LOCK GRATING WITH CONFIDENCE – We haveconstructed our load tables using the most stringentinterpretation of the AISI standards: Our safe allowableloads guard against harmful local distortion as well asfailure. Some manufacturers have prepared allowable loadtables guarding against failure only.

GRATE-LOCK® LOAD TABLES


SAFETY GRATING STAIR TREADS

ll Safety Grating Products are excellent candidates for fabrication and installa-tion as stair treads. The versatile walking surfaces offered by Grip Strut, Perf-O

Grip, Grate-Lock and Traction Tread offer products suitable for nearly allapplications. Stair treads are manufactured with welded end carrier plates which arepre-punched with holes allowing the treads to be bolted to the stair stringers. Inmany cases, the side margin of standard safety grating channels provides a definedvisible nosing line. Where increased visibility and safety are desired, specify theproducts shown with supplementary cast abrasive, Traction Tread, or formed checkerplate nosings.

The load data below takes eccentric loads into consideration. Although loadvalues include allowances for normal impact conditions and unusual pedestriantraffic, be sure to make provisions for special uses and loads involving unusualimpact or vibratory forces. Load carrying capacity of stair treads increases as channelheight and gauge of material increase.

FIBERGLASS GRATING

ombining unmatched corrosion resistance with strength, long life and safety, fiberglass grating is

proven to deliver years of reliable service, even in themost demanding environments. Indiana Gratings offerstwo types of quality fiberglass grating distinguised by theirmethod of construction. These gratings are classified asmolded products and pultruded products. Molded grating(illustrated on pages 35-38) is unmatched in its ability towithstand the effects of corrosion and is highly impactresistant. Pultruded grating (illustrated on pages 39-41)provides reliable corrosion resistance and higher loadbearing characteristics.

CHARACTERISTICS – Molded and pultruded fiberglassgratings are often superior to conventional metallicgratings when installed in highly corrosive environments.Fiberglass grating can be fabricated with simple handtools, is light in weight, and is easy to install. Forenhanced worker safety, fiberglass grating is slip-resistant,non-conductive, and is available with flame spread ratingsunsurpassed by any competitive product. In-line with thegrowth of ergonomics as a factor in facility planning, the

inherentresiliencyof fiberglassgrating can alsoincrease workerproductivity by greatlylessening back andleg fatigue.

APPLICATIONS – The uniquefeatures inherent in fiberglass gratingsmake these products ideal candidates inthe most demanding industrial applications.Chemical processing, refining, offshore, pulpand paper, food and beverage, marine (includingmilitary vessels), water and wastewater treatment,electronics and plating are just some of the applicationswhere the performance of fiberglass gratinghas proven superior.

PULTRUDED GRATING

The resin systems used in fiberglass grating providesuperior resistance to the effects of corrosion andultraviolet exposure. Uniquely formulated resinsystems are also responsible for the grating’s fireretardant characteristics.

Because various applications present differentperformance requirements, Indiana Gratings offers anumber of standard resin systems, each offering uniqueproperties. For maximum versatility and selection,molded grating is stocked in five resin systems, the mostextensive selection in the industry. Pultruded grating isoffered in two resin formulations, in order to best matchthe requirements of the specific application.

RES IN SYSTEMS

In keeping with its quality role, only FibergrateFiberglass Gratings are classified by UnderwritersLaboratory for meeting established standards for chemicalexposure, flame spread, load-bearing characteristics andslip-resistance. Thiscertification by anindependent third partyprovides the user a strongsense of security knowingthat Fibergrate meetsestablished performancespecifications. No othermanufacturer of fiberglassgrating can make that claim!

PULTRUDED FIBERGLASS GRATING

CHARACTER I S T I CS O F PU LTRUDED GRAT I NG

• HIGH STIFFNESS• MAINTENANCE FREE• NON CONDUCTIVE• CORROSION RESISTANT• SKID RESISTANT• LIGHTWEIGHT• UV RESISTANT

ultruded grating provides performance far exceeding that of alternative products with a comparable

installed cost. This advanced fiberglass grating is designedfor use in a wide range of applications that requirestrength and corrosion resistance. Manufactured with ahigh percentage of glass within the laminate, pultrudedgrating combines durability with the highest strength andstiffness available in fiberglass grating. Pultruded gratingcan be used with confidence in applications where widesupport spans are required.

Using both a mechanical and chemical lock,pultruded grating is manufactured with a two-piece crossbar configuration which increase the panel’s supportand stability under load. The standard grit-topwalking surface provides sure footing and aprotective synthetic veil, covering the exteriorsurface of the load bearing bars allows thegrating to reliably withstand constantexposure to ultraviolet rays.

Pultruded grating is available in two resin formulations for an accurate match of product characteristics with theapplication. Both resin systems provide corrosion resistance that is superior to that offered by metal grating.

ISOFR (YELLOW) – This isophthalic polyester resin formulation provides a low flame spread rating of 25 or less and isdesigned for applications where there is moderate exposure to corrosive elements.

VEFR (GRAY) – With a flame spread of 25 or less, this vinyl ester resin system provides dependable resistance to bothacidic and alkaline environments.

PULTRUDED GRATING RESIN SYSTEMS

Type ”M” 316 stainless steel hold down clips used tosecure panels to a support using two adjacent grating barsfor a secure fit.

Type “G” stainless steel hold clips designed to attachgrating to any structural member flange, 3/4” or smallerin thickness, with no drilling required.

Type “FB” 316 stainless steel flange blocks fit insideclose mesh products allowing for installation of capscrews from the top surface of the grating.

Type “RK” 316 stainless steel fasteners offer effectiveand more secure means for installing pultruded grating.

PULTRUDED GRATING LOAD TABLESTHE FOLLOWING LOAD TABLES WERE DEVELOPED IN STRICT CONFORMANCE WITH THE FIBERGLASS LOAD/DEFLECTION CRITERIA PRESENTED BELOW. U – UNIFORM IN LBS. PER SQ. FT., C – CONCENTRATED LINE LOAD INLBS. PER FT. OF WIDTH, ΔU – UNIFORM LOAD DEFLECTION IN INCHES, ΔC – CONCENTRATED LINE LOAD DEFLECTION IN INCHES.

MANUFACTURING CONTROL LIMITS – The load/deflection values given in this brochure aremedian values developed through a strict quality assurance program. The manufacturingcontrol limits on stiffness for all panels are plus or minus 7.5% of these median values.This represents the tightest control on performance variation in the industry, basedpublished data.

ULTIMATE CAPACITY – Molded and pultruded grating product lines have been tested totheir ultimate capacities. Ultimate Capacity represents a complete and total failure of thegrating and is presented to illustrate the reserve strength of the grating at a given span.Ultimate capacities are not to be used for design; functionality of the grating is limited toMaximum Recommended Load.

BARS PER FOOT OF WIDTH – The preceeding molded grating load tables were developedusing 8 bars per foot of width for 1-1/2” square mesh grating and 12 bars per foot of widthfor rectangular mesh grating for uniform and concentrated loads. Some manufacturers use9 bars per foot of width and 13 bars per foot of width respectively. This can overstategrating performance by as much as 12.5%. When comparing the presented products tothose using 9 or 13 bars, multiply the deflection reported in this catalog by 0.89 for squaremesh products, and 0.92 for rectangular mesh products.

WALKING LOADS – Walking loads, typically 50-65 PSF maximum or 250 lbs. concentrated pointload, are recommended for pedestrian traffic. Deflections for worker comfort are typically limitedto the lesser of 3/8” or Clear Span divided by 125; for a firmer feel, limit deflection to the lesser of1/4” or Clear Span divided by 200.

STATIC LOADS – The allowable loads in the tables are for Static Load Conditions atambient temperatures only. Allowable loads for impact or dynamicconditions should be a minimum of ONE-HALF the valuesshown. Long term loads will result in added deflection due tocreep in the material and will also require higher safety factorsto insure acceptable performance. For applications atelevated temperatures, consult Indiana Gratings. Thedesigner is further referenced to ASCE Structural PlasticsDesign Manual.

FIBERGLASS GRATING STAIR TREADS

MOLDED GRATINGSTAIRTREADS

PULTRUDED GRATINGSTAIRTREADS

FIBERGLASS GRATING CHEMICAL RESISTANCE GUIDE

ibertred Grating Stair Treads manufactured from quality Fibergrate molded grating exceed tough

OSHA standards for safety, strength, durability andcorrosion resistance. Fibertred is available in the same highperformance resin formulations as Fibergrate moldedgrating and also provides excellent safety characteristics –slip resistance, non-conductivity and a low flame spread.

Unique cutting channels, spaced at 6” intervals,provide efficient utilization when custom fitting intostairways. These channels also ensure that all standardstairtreads widths are terminated with closed ends. A 1-1/2”

wide gritted strip is molded into the lead edge of the treadfor superior slip resistance. (Additional support is requiredfor treads exceeding 42” in width).

Cost efficient, durable Pultruded Stair Treads areslip-resistant and non-conductive. These stair treads offerthe same level of safety, strength and corrosion resistanceas other pultruded fiberglass products. Designed for use inapplications where wider support spans are required,Pultruded Stair Treads are available in 1”, 1-1/2”,and 2” thicknesses.

NOTES:1. IT IS SUGGESTED THAT STAIR TREAD DEFLECTION BELIMITED TO SPAN/150. DEFLECTIONS BASED ON THISRATIO ARE PROVIDED AT THE TOP OF THE TABLE.

2. DEFLECTIONS IN THE BODY OF THE TABLE ARE FORCONCENTRATED LOADS OF BOTH 250 LBS. AND 500LBS. A CONCENTRATED LOAD IS APPLIED AT THECENTERLINE OF THE TREAD, OVER A WIDTH OF 4”AND A DEPTH OF 6”, STARTING AT THE NOSING EDGETO SIMULATE THE LANDING OF A FOOT.

3. DEFLECTIONS ARE NOT APPRECIABLY DIFFERENTDUE TO STAIR TREAD DEPTH. ACTUAL DEPTH WILLVARY DEPENDING ON STAIR TREAD CONFIGURATION.

EXPANDED METAL

REGULAR EXPANDED METALRegular Expanded Metal is an

open mesh, finished product thatis simultaneously die-cut andexpanded as it moves throughprogressive dies on a press. In theexpanding process, the metal canbe expanded up to ten times its original size, lose up to 80% of its originalweight per square foot, and still retain form and rigidity. (Regular ExpandedMetal can also referred to as “Raised” or “Standard” Expanded Metal.)

FLATTENED EXPANDED METALFlattened Expanded Metal is Regular

Expanded Metal that has been passedthrough flattening rolls (cold rolled). Thisrolling process reduces the thickness ofthe sheet, stretches the pattern of thesheet, and provides a smooth flat finish.

All popular sizes are stocked in bothregular and flattened sheets.

FABRICATION

SHEAR INGIndiana Gratings has fabrication capacity and will

gladly shear perforated and expanded metals tospecification. When shearing expanded metals, closeattention should be paid to bond and marginrequirements. Pieces can be “Bond Sheared”or “Random Sheared” subject tomanufacturing tolerances.

Bond shearing produces pieces with equal, closeddiamond configurations on all four sides. Random shearing produces pieces with partial diamonds on up toall four sides. Random sheared pieces often have sharp exposed partial strands which should be protected by“U” edging or finish framing.

When finish framing of expanded or perforated metals is desired, U-Edging is apopular option. Manufactured from 14, 16 or 18 gauge carbon steel in stock lengths,U-Edging is available 1” or 1-1/2” wide with openings that accommodate varioussheet thicknesses. Aluminum and stainless steel U-edging is available on special order.

MATERIAL: Indicate type of material desired (carbon steel, stainless steel, oraluminum).

STYLE NUMBER: Indicate style number (such as 3/4” - #9R) which will indicatethe desired diamond size and sheet thickness.

SURFACE: Confirm desired surface, regular or flattened sheet.

QUANTITY & SIZE: Indicate quantity desired and piece sizes including SWD andLWD. Provide material list for cut-to-size pieces and sketches for irregularshapes. For sheared to size orders, review shearing options illustrated above.

FINISHING: Specify any special finish requirements (galvanizing, paint or anodizing).

EXAMPLE ABond sheared all four sides

EXAMPLE BBond sheared one side, one end,random sheared one side, one end

EXAMPLE CBond sheared two sides (SWD),random sheared two ends (LWD)

EXAMPLE DRandom sheared all sides and ends

U - EDG ING ACCESSOR I ES

MATER I A LS / F I N I SHESAll expanded metals are available in a variety of metals; carbon steel,

stainless steel, and aluminum. Carbon steel expanded metal is lightly oiled andshould be cleaned prior to the application of finish coatings. Additionally,carbon steel expanded metals can easily be painted or galvanized to enhancecorrosion resistance. (Certain popular carbon steel items are stocked galvanized.)

Aluminum products are stocked mill finish and can be anodized or epoxycoated. Stainless steel products are similarly stocked with a mill finish. Stainlesssteel can be electroplated to provide for a bright finish or abrasive blasted toprovide a uniform matte finish.

NOMENCLATUREDIAMOND - The open area formed by strands and bonds. Normally the open area is diamond shaped.STRAND - The single metal strip that forms the perimeter of the diamond. The strand thickness is thethickness of the metal from which the expanded metal is produced. The strand width is the amount ofmaterial advanced before forming the next diamond.BOND - The point where adjacent strands intersect. The bond width is always twice the width of the strand.LWD - Long way of the diamond - indicates the distance from center-to-center of linear bonds in the long direction.SWD - Short way of the diamond - indicates the distance from center-to-center of linear bonds in the short direction.LWO - Long way of the opening - indicates the clear opening of the diamond in the long direction.SWO - Short way of the opening - indicates the clear opening of the diamond in the short direction.

WIRE CLOTH

TYPE PC - P LA I N CR IMPSquare pattern wire cloth using warp and fill wires of equal size. Warp wirespass over and under fill wires in an alternating pattern at adjacent intersections.

Welded Wire Cloth is available incarbon steel and select stainless steel

alloys. Manufactured in a wide variety ofwire diameters, welded cloth is produced in a

square or rectangular mesh. Warp and fill wireslay flat and each intersection of Welded Wire

Mesh is electrically welded for maximum crosssectional strength. Welded Wire Mesh is available in

roll or flat panel form.

The strength and versatility created by the all-weldedconstruction make Welded Wire Cloth a preferred choice

for designers and fabricators. This rigid product can besheared, formed, fabricated and finished to the most

demanding specifications.

Popular for handrail infill panels, Welded Wire Cloth is available with attractive squareor rectangular mesh openings. Properly specified, Welded Wire Cloth conforms to current ADA

requirements. Indiana Gratings will promptly provide stock panels for your own fabrication, or, ifdesired, we will gladly fabricate infill panels complete with framing and connection plates. Just ask!

WOVEN W IRE C LOTH & CR IMP S TY LES

TYPE I C - I N T ERCR IMPWire cloth manufactured with crimped warp wires filled at every othercrimp with fill wires. The resulting cloth provides superior rigidity andgreater stability. Popular for screens and architectural applications.

TYPE L C - L OCK CR IMPVersatile wire cloth manufactured to hold accurate openings. Each intersectionis formed with straight sections of fill wires woven within straight sections ofwarp wires. Fill wires are woven in an alternating pattern, top and bottom.

TYPE F T - F LAT TOP CR IMPAll crimping is offset to one side producing a wire cloth with all wiresurfaces in a single plane on the top. This even surface allows for thesmooth flow of materials over the top surface of the cloth.

WIRE CLOTH

WIRE CLOTH IS COMMONLY AVAILABLE IN THE FOLLOWING MATERIALS:

CARBON STEEL – plain low carbon steel typically ranging from C1006 toC1012 alloy, drawn from rod. Combines strength and weldabilitywith economy.

GALVANIZED BEFORE WOVEN – Carbon steel coated with a light layer of zincduring the manufacturing process. Adequate corrosion resistance isprovided for most indoor applications, but not recommended foroutdoor installations.

GALVANIZED AFTER WOVEN – Carbon steel coated with a heavy layer of zinc afterthe manufacture of the mesh. Excellent for long term corrosion protection.

HIGH CARBON STEEL – Abrasion resistant steel used for applications facingsignificant wear such as media filtering or sorting. Abrasion resistantsteel can be difficult to weld, consider mechanical fastening tosupporting structure.

STAINLESS STEEL – Commonly manufactured in 300 series alloys. Type 304 ismost popular, but also available in types 309, 310, 316, 321 & 347. Series400 alloys are also available on special order.

ALUMINUM – Light weight and mildly resistant to corrosion, aluminum alloysare readily available. Alloy 1350 is most common and can be easily weldedand anodized. Also available are alloys 5056 and 6061.

NICKEL BASED ALLOYS – Inconel 600, Monel 400, Nichrome V and HastalloyC276 offer specific characteristics desirable in specialized environments.

SPECIALTY ALLOYS – Copper based alloys, bronze, brass and titanium are alsoavailable for all woven products. Contact our sales engineers for assistancein selecting the proper specialty alloy for your application.

CALENDARED WIRE CLOTH – wire cloth that has been passed through heavyrollers to reduce the thickness of the material or flatten the wireintersections to produce a smooth surface.

CLEAR OPENING – the space between adjacent parallel wires.

CRIMPS – corrugations placed in the wire which allow the wires to bewoven together. The placement and style of the crimps determine thelocation of the intersections and permit tight locking of the wires.

FILL WIRES – wires running across the width or short way of the materialas woven. (Also referred to as shute or cross wires.)

GAUGE – a measure of wire diameter commonly used by manufacturers. Toavoid confusion between ferrous and non-ferrous gauge dimensions,always specify your desired wire diameter in decimal inches.

HARDWARE CLOTH – square mesh cloth, galvanized after assembly andavailable in either woven or welded construction.

MESH – the number of openings in a lineal inch measured from thecenter of one wire to a point one inch distant.

OPEN AREA – the proportion of open space as a percentage of the totalmaterial area.

SELVAGE – a finished edge used to prevent fraying or unraveling of wovenwire cloth.

WARP WIRES – wires running parallel to the length or long way of thematerial as woven.

N O M E N C L AT U R E


Open area, expressed as a percentage, is the ratio of clear area to screen area for a specific wire cloth. This ratio is useful for comparing how readily various materials or elements will flow through the cloth.

To calculate the open area of square mesh wire cloth, use the following formula:

EXAMPLE: To find the open area for square mesh wire cloth using 1/2" mesh , .120 wire:

1 .0 opening, .0

(.500 – .120)2

(.500)2x 100 = 57.8% OPEN AREA

SUPERTREAD CAST STAIR NOSINGS & TREADS

afety, durability and impact resistance are just some of the outstanding features that make IGI SuperTread Nosings and Treads preferred components for stairs and landings. Commonly available in cast iron and cast aluminum, SuperTread products are also readily available in extruded aluminum carriers with a solid abrasive fill.

Maximum pedestrian safety is provided by the anti-slip walking surface and OSHA conforming barrier free installation. SuperTread Nosings form a highly visible, defined anddurable lead edge at the primary point of contact on stairs and landings. Impact resistant, SuperTread Nosings and Treads protect exposed concrete edges that are often prone tochipping and cracking.

Call for our complete 28 pagecatalog of Kee Klamp Fittingsand our 24 page instruction

manual, “How toBuild with KeeKlamp Fittings.”

FEATURES:• QUICK ASSEMBLY OF STRUCTURAL PIPE WORK• 100% REUSABLE• NO WELDING OR THREADING REQUIRED• NO DRILLING OR BOLTING REQUIRED• CUT RAILING COSTS BY UP TO 50%• MEETS OSHA STANDARDS

ee Klamp fittings are strong, malleable cast-iron slip-on pipe fittings that allow for the quick

assembly of a wide range of rigid pipe-framed structures.Handrails, racks, awnings, greenhouses, playgroundequipment, light grid systems are just a few of the creativestructures possible.

Kee Klamp fittings are designed for use with standardSchedule 40 or 80 pipes (sizes 1/2” to 2”). Case-hardenedset screws, with KeeKoat finish securely lock the fittings tothe pipe. For longevity, Kee Klamps are galvanized makingthem ideal for indoor or outdoor use.

The many types of Kee Klamp fittings detailed on thenext two pages give unlimited scope to the engineerdesigner, making possible the fabrication of the unusual

type of structure as well as the usualrailings, storage racks, etc.However, most structurescan be designed from justtwo or three types of KeeKlamp fittings.

Kee Klamp RailingFittings in sizes to suit 1-1/4”,1-1/2” and 2” I.D. pipe meetand in meet and in mostcases exceed the OHSArequirement to withstand aload of 200 lbs. applied tothe top rail.
