Drawings and Specifications

The Buyer shall be expected to furnish to the Seller a set of construction drawings and specifi cation of current issue showing the layout of supports and fl oor openings correctly dimensioned, together with the sizes and types of grating required.

Limits of Responsibility

In the absence of written notice to the contrary, the Buyer’s construction plans and specifi cations shall be assumed by the Seller to be correct in all details, and the Seller’s responsibility shall be limited to furnish the products in accordance with their documents.

Information to be Provided

If drawings and specifi cations are not available, Buyer shall provide the following:

• Specify Alloy (steel, aluminum, stainless steel, etc.) • Type of grating (welded, pressure-locked, swage-locked, riveted, fi berglass, etc.) • Bearing bar size and center to center spacing of bearing bars and cross bars • Span (bearing bar direction) • Drawing: area to be covered, including all cut-outs and critical dimensions • Type of anchorage (welded, saddle clip, G-clip®, weld lugs, etc.) • Specify Finish: mill fi nish, painted black, galvanized, anodized or sand blasted • Specify smooth, serrated or Mebac® surface • Specify if banding, kick plates, nosings or any other types of fabrication are required • Shipping instructions

Approval Drawings

If requested by the Buyer, the Seller shall submit detail drawings for approval. Buyer shall return drawings marked with his/her approval or desired changes. Any additional work not contemplated by the contract may result in additional negotiations between Buyer and Seller to reach agreement on the cost of the changes. After all necessary changes are made; the drawings shall be re-submitted to the Buyer for fi nal approval. The Seller shall not proceed with any shop work until the drawings are fi nally approved. (NOTE: All American Grating can accept the physical drawing or the drawing can be e-mailed in the following formats: PDF, AI, DXF, DWG or a high resolution TIFF, e-mailed drawings help minimize the time needed for the drawing approval process).

Quantity Measurements

Quantity measurements for gratings ordered to specifi c dimensions, without drawings, shall be based on width times span of each panel, with no deduction made for cutouts, unless allowances for cutouts have been negotiated.

Final grating quantities supplied from drawings shall be on the basis of gross area measure center to center of supports, or back to back of supporting angles or channels, or overall dimensions of grating, whichever is larger, with no deductions for clearances. Allowances for cutouts will be determined as follows:

Deductions in area for circular cutouts will only be allowed when the diameter of the cutout exceeds 3'-6". The deductions allowance shall be equal to one half the square of the diameter of the cutout.

Deductions in the area for cutouts other than circular shall be allowed only when the cutout area exceeds nine (9) square feet.

No deductions shall be allowed for any triangular segment or corners of grating wasted in skew cuts.

Measurement of cuts shall be on the basis of a minimum of one (1) lineal foot per cut per panel. Any cut in excess of one (1) lineal foot shall be measured to the next highest lineal foot. Measurement of bandings, toe plates and nosings shall be on the same basis as that of cuts.

Changes in Scope of Contact

If at any time during the course of the work the Buyer orders changes made which require materials and/or labor not called for in the original bidding plans, the cost of making such changes shall be paid for by the Buyer at a price to be agreed upon.

Field Work

The Seller shall not be responsible for taking actual measurements on construction work in the fi eld.

Back charges for fi eld work of any kind are not acceptable without prior written authorization by the grating supplier.

Back Charges

Buyer shall immediately notify seller upon discovery of unsatisfactory material; Seller shall acknowledge complaint and initiate an investigation. Seller shall be given the opportunity to inspect product PRIOR TO ANY CORRECTIVE WORK BEING DONE.

Seller is responsible for providing grating in accordance with approved drawings and specifi cations. Seller is NOT responsible for fi eld changes not received and approved by Seller prior to grating fabrication, improper fabrication and/or erection of supporting members.

If the inspection and investigation confi rm errors in Seller’s fabrication, the Seller agrees to replace defective material at no charge to the Buyer.

Surfaces

Smooth Top

All American Grating’s Smooth Top does not have a notch punch therefore this grating can become slippery. Smooth Top is not recommended for applications where slip-resistance and traction is a factor.

Perspective View

Type Two SerrationAll American Grating’s Type Two Serrated Grating uses a half-circular notch to create an aggressive surface allowing for traction and slip-resistance.

Profi le View

Perspective View

Type One Serration

All American Grating’s Type One Serrated Grating uses an 1/8" notch to create a slip-free surface perfect for any application where traction and safety is a high concern.

Profi le View

Perspective View

Mebac®

Profi le View

In the patented Mebac® process, aluminum grit is bonded to a metal base with molten metal. The metal and abrasive grit composite provides a non-sparking, non-corrosive surface that provides greater slip-resistance under slippery conditions.

NOTE: Spans and loads to the right of the heavy line exceed a defl ection of 1/4" for uniform loads of 100#/sq. ft. which provide safe pedestrian comfort, but can be exceeded for other types of loads at the discretion of the engineer.

NOTE: When calculating loads that require serrated bearing bars, subtract 1/ 4" from your grating depth and use that load table.

EXAMPLE: (1 1/4" x 3/16") serrated bearing bars would have the same strength as (1" x 3/16") non-serrated bear-

ing bars, therefore you would use the (1" x 3/16") load table.

U - Safe Uniform Load in lbs. per sq. ft.

C - Safe Concentrated Load in lbs. per foot of grating width.

D - Defl ection in inches.

Static Load Table – Loads & defl ections are theoretical, based on a maximum allowable fi ber stress of 18,000 PSI. E = 30,000,000 PSI

Steel Pressure-Locked – 15/16" Center to Center of Bearing BarsSteel Welded Grating – 15/16" Center to Center of Bearing Bars

Carbon Steel Material: ASTM A-1011


NOTE: When calculating loads that require serrated bearing bars, subtract 1/4" from your grating depth and use that load table.

EXAMPLE: (1 1/4" x 3/16") serrated bearing bars would have the same strength as (1" x 3/16") non-serrated bearing bars,

therefore you would use the (1" x 3/16") load table.

U - Safe Uniform Load in lbs. per sq. ft.

C - Safe Concentrated Load in lbs. per foot of grating width.

NOTE: When calculating loads that require serrated bearing bars, subtract 1/ 4" from your grating depth and use that load table.EXAMPLE: (1 1/4" x 3/16") serrated bearing bars would have the same strength as(1" x 3/16") non-serrated bearing bars, there-fore you would use the (1" x 3/16") load table.

The following shows the capacities on the basis of vehicular load distribution and concentrated loading per foot of grating width for a given span.

Calculations for concentrated load are similar in format to those for Light Duty Steel Grating (except F = 20,000 (psi)). Calculations for vehicular loadings are based on AASHTO Standard Specifi cations for Highway Bridges and utilize the formulas to the right of this text.

Notes:

a) For continuous spans, use continuity factor = .80b) This distribution results in larger grating sizes for lighter trucks on shorter spans. Spans shown for H15/H20 refl ect the more critical condition.c) The fork lift wheel loads and load distribution patterns depicted below, generally and only partially represent the broad range of rubber-tired lift trucks available. For those applications falling outside of these examples, please contact All American Grating.d) Wheeled vehicles with urethane tires should NEVER be used in conjunction with open grid bar grating.e) HS20 is the same as H-20 and HS15 is the same as H-15. The “S” stands for semi-trailer. E

All American Grating offers a special fabrication that combines heavy and light bearing bars to produce a product with unique capabilities. Deep heavy-duty bars provide the strength to support vehicle loads; these deeper bars are alternated with lighter, shallower bars that serve to reduce the grating’s clear opening. This is an extremely economical solution for certain demanding applications. Call All American Grating for additional details.

Egg CratesEgg crates are constructed using equal size bearing bars and cross bars. A notch is punched into the top half of the bearing bar; a similar notch is punched into the bottom half of the cross bar. When assembled and welded (generally using a full depth fi llet weld in opposite corner of the bb/cb joint), a grating with equal strength in both directions is produced. Due to equipment restrictions, not all bar sizes can be used to construct an Egg Crate. Please contact All American Grating with specifi c requirements.

G– Clip®

Fastens grating to a horizontal-facing steel structural member edge.

G-Clips unique top is better for holding strength and to suit 19 - W grating. Second, a G-Clips patented bottom connects to the beam underside. A hex-headed cap screw connects the two, and its length suits the grating height being installed.

• NO welding or hot work required

• NO damage to protective coatings

• NO power set bolts

• NO drilling or tapping

• NO special tools

• NO ladders or scaffolds

• Increased holding strength

• Available in Galvanized or Stainless Steel

• Resists vibration and corrosion

• Easy to remove

Blank Hinge (Carbon Steel) These hinges can be spot welded or drilled with holes for screws or rivets for mounting. They can be cut to length with a hacksaw and are reversible for right- and left-hand mounting. Hinge and pin are made of the same material unless indicated otherwise. From a folded position, hinges have at least 265° of movement.

Fastening Systems

Grate-Fast® enables rapid and secure connection of open grate fl ooring to steel sections. Grating can be secured by one man only, working from above, without the need to drill the steel, or weld on site.

Only for openings with 1" between bearing bars.

Uniform Loads - Lbs. /S.F. (Defl ection in Inches)

CorGrate® Molded SM (Square Mesh) with its high resinto glass ratio provides the maximum corrosion protection of any All American Grating products. Unique to molded sections, the bars are the same construction, depth, and spacing in both directions which results in equal strength in either direction.The top surface is a skid resistant, meniscus (concave) surface, with an optional Quartz or Aluminum Oxide Grit.

NOTES:

Defl ection for uniform loads is limited to L/120 with L representing clear span length in inches. For typical pedestrian traffi c, uniform load of 50 PSFis recommended with defl ection not to exceed .375".

Defl ections for concentrated loads are shown for the same span conditions as for uniform loads.

NOTES:

Defl ection limits can be higher for fi berglass gratings as they are more resilient than metal materials.Bold numerals indicate defl ection greater than .375" or L/120. For these conditions, sustained loads or data not shown, an All American Grating representitive should be contacted for assistance.

Failure loads have been determined by applying a 2.5 Factor of Safety (FOS)to the Ultimate Capacity of the grating.

For 1" and 11/2" grating use SFM stainless steel saddle clips.For 2" grating use WHM stainless steel saddle clips.

Molded Fiberglass Grating Cutting Diagram

Equal Stubs Random Cut

No Stubs• Stubs are cut fl ush with ends of CorGrate®.

• This type of cut adds cutting and waste, but is the most cosmetic of the cuts.

• The tolerance for this cut is: ± 1/4"

Stubs on One End

• Stubs are cut fl ush on three ends of CorGrate®, while leaving on side with stubs.

• This style of cutting has an average cutting time and waste.

• The tolerance for this cut is: ± 1/4"

• Stubs are cut fl ush on two sides of CorGrate® and equally cut on the other two sides.

• Common Cutting for Stair Treads.

• The tolerance for this cut is: ± 1/ 4"

• Stubs are cut randomly, some stubs maybe shorter or longer than others.

• This is the most economical style of cutting, but is the least cosmetic of the cuts.

• The tolerance for this cut is: ± 1/ 4"

Every All American Grating Fiberglass order comes with UV Inhibitors standard

Surface Veils can be added for extra protection but must be specifi edAll cuts should be resin sealed


CorGrate® FW (Flush Top Wide Flange) gratings are a superior and economical walking surface with exceptional stregnth and corrosion protection. With sections offering either 60 or 40% open area, the FW products are an excellent choice for working platforms. The sections with fl ush top cross bars are usually preferred for walking surfaces over non-fl ush bar products.

NOTES:

Defl ection for uniform loads is limited to L/120 with L representing clear span length in inches. For typical pedestrian traffi c, uniform load of 50 PSF is recommended with defl ection not to exceed .375".

Defl ections for concentrated loads are shown for the same span conditionsas for uniform loads.

NOTES:

Defl ection limits can be higher for fi berglass gratings as they are more resilient than metal materials.

Bold numerals indicate defl ection greater than .375" or L/120. For these conditions, sustained loads or data not shown, an All American Grating representitive should be contacted for assistance.

Failure loads have been determined by applying a 2.5 Factor of Safety (FOS) to the Ultimate Capacity of the grating.

Standard panel widths are 24", 36" & 48".Standard lengths are 20' and 24'.Standard color for Isophthalic Polyester (PF) is yellow with yellow top grit. Standard color for Vinyl Ester (VF) is gray with gray top grit.Standard gratings are furnished with gritted, skid resistant top surface.Standard cross bar spacings are 6" or 12" on center.

For FW60 grating use WHM stainless steel saddle clips.For FW40 grating use W4S-1 stainless steel saddle clips (1" high grating).For FW40 grating use W4S-2 stainless steel saddle clips (11/2" high grating).

CorPlate™Fiberglass Grating

CorPlate™ is a premium quality FRP fl at sheet provided in 1/8", 3/16", 1/4", 3/8" and 1/2" thicknesses. The top surface can be smooth or have a gritted slip resistant surface. For covered grating applications, CorPlate™ is adhered by an epoxy to CorGrate® molded or pultruded gratings to form a fl at and corrosion resistant working surface. These materials are utilized for applications where free passage of light and air is not desired nor drainage a requirement as in pit covers where reduction of corrosive vapors is needed. HI heavy duty covered grating is recommended for areas exposed to turning wheel traffi c.

CorPlate™ Covered Grating

CorPlate™ Profi le View

Phenolic Resin and Modar Resin is optimal in conditions where fi re resistance, low smoke and low toxic fumes are critical concerns. It can stand up to the harshest environments and provide years or service. Non-fl ammability enables it to withstand direct fl ame for an extended time without sustaining major structural damage. Phenolic Grating and Modar Grating are as strong as Iso-Polyester or Vinyl Ester Resin Grating, but with lower smoke and fl ame levels.

For installation where light weight, low cost, easy to install fl ooring is required. All American Grating's Aluminum plank may well be the perfect solution.

Strong & Versatile

All American Grating's high quality extruded 6063-T6 Aluminum plank sections are available in sizes and styles to meet your needs. Plank sections are 6" wide, with lengths up to 26'-0". Their integral I-beam vertical supports provide an excellent strength to weight ratio. They can be fabricated to your specifi cations at the factory or cut at the job site as needed.

Design & Construction Features

Punched or Unpunched

Plank may be offered either way. Unpunched, where alight weight, solid fl oor is required or punched to provide for passage of air and light.

Strength

I-beam sections form integral part of the extrusion, therefore punch outs do not weaken All American Grating’s Aluminum plank. The strength of All American Grating’s Aluminum plank comes from the bearing bars. The cut-out portions of the surface provide passage for light, heat and air, but do not reduce the load bearing capacity of the fl ooring.

Universal Handrail Bracket

The new Universal Handrail Bracket has been designed for use on Heavy Duty Grip Strut ® Walkway, Light Duty Grip Strut ® Walkway and Perf-O Grip® Walkway with both the tube and angle type handrails.

Not only can the Universal Handrail Bracket be used with a number of different types of walkways, it can be bolted to the walkway material or mechanically fastened. The option of me-chanically fastening it allows it to be placed anywhere along the walkway side channel without the need for drilling holes in the toe board. This saves time and money during installation.

Our walkways make very effi cient mechanical walkways or in-spection walkways because the material is made in a one piece construction with toe boards and in the direction of the spans. It requires no additional cutting, framing or welding, making this an easy and effective choice for your next walkway project.

ADA Approved

A grating to have clear openings between bearing bars not greater than 1/2".

Alloy Refers to material specifi cation. For example, the aluminum standard alloy is 6063.

Anchors & Fasteners A device by which grating is attached to its supports.

Band

A fl at bar welded to a side or end of a grating panel, or along the line of a cutout, and extending neither above nor below the bearing bars.

Load-Carrying Band A band used to transfer the load between bearing bars (weld one side of every bearing bar). Trim Band: A band which carries no load, but is used chiefl y to improve appearance, fl atness and protects sharp edges.

Bar Grating An open grid assembly of metal bars in which the bearing bars, running in one direction, are spaced by rigid attachment to cross bars running perpendicular to them or by bent connecting bars extending between them.

Bearing Bar

The main load carrying bar which runs the same direction as the span.

Bearing Bar Centers

The distance center to center of the bearing bars.

Bottom Bar/Shim Bar

A bar used to raise height of grating or wear plate.

Circular Cut-Band

The circular cutting and banding of a panel to conform to a specifi c layout. Example: grating going around a tank or pipe.

Clear Opening

The distance between the inside faces of bearing bars.

Clear Span

The distance of the clear opening between the grating supports. Used to calculate load capabilities and strength of grating. See detail below.

Close Mesh

Bearing bars spaced close together – bearing bar center 11/16" or under.

Cross Bar Centers

The distance center to center of the cross bars.

Cross Bars

The connecting bars, made from a steel strip, slit sheet, rolled bars or from rolled or extruded aluminum, which extend across the bearing bars, usually perpendicular to them. They may be bent into a corrugated or sinuous pattern, and where they intersect, the bearing bars are welded, forged or mechanically locked to them.

Dove Tail

Used in the process of pressure locking grating – aluminum or steel. See Pressure-Locked Grating.

Electro-Forged

A process combining hydraulic pressure and heat fusion to forge bearing bars and cross bars into a panel grid (Forge Welded – Machine Welded). See Welded Grating.

End Dimension (End Gauge)

The distance from an end of grating to center of fi rst cross bar. See detail below.

End Plate

A fl at bar welded to the ends of stair treads for bolting to stair stringers.

Equal End Dimensions

The same distance from the end of bar to center of the fi rst cross bar on both ends of panel (must be specifi ed).

Filler Bar

A bar welded between two grating panels to close the spacing.

Finish

The coating, usually paint or galvanizing, which is applied to the grating.

Flat

Within tolerance of bow and crown – does not rock or bounce.

Flattening

A means of making bowed grating fl at.

Grade

Refers to steel – Heavy Duty is ASTM A36

Light Duty is ASTM A1011 CS Type B.

Flush Top Grating

A type of aluminum swage-locked grating in which the cross bars and bearing bars are in the same plane relative to the top surface of the grating using the swaging process. Also, could be pressure-locked grating with rectangular cross bars.

Structural I-Beam Structural I-Beam Bearing BarsCross Bars


Hinge

A device to create movable or swing grating (Piano Hinge, Butt Hinge, Heavy Duty Butt Hinge, Double Acting Hinge).

I-Bar

Extruded aluminum bearing bar having a cross sectional shape resembling the letter “I”.

Intersection

The point where the bearing bar and cross bar intersect or cross. In heavy duty grating with a rectangular cross bar; an intersection has four (4) sides.

Longitudinal

Refers to measurements along the span of the grating.

Mebac®

This is a type of surface, not a fi nish – an applied metal gritted anti-skid surface.

Nosings

An L-shaped section, usually made of checker plate or cast iron and cast aluminum abrasive material.

Notched Bar

A cut out in the bearing bar. A burn out or punch.

Notched Grating

A fabricated corner cut out or small cut out.

Piece Mark

(Mark Number) Used to identify each unique piece.

Plug Weld

A fi llet weld used for joining cross bars to bearings on hand-welded grating. Pressure-Locked Grating

Pressure-locked means bearing bars are locked in position by cross bar deformation instead of riveting or welding.

• Press assembly of rectangular cross bars into slotted bearing bars (Dove Tail).

Reticuline Bar

A sinuously bent connecting bar extending between two adjacent bearing bars, alternately contacting and being riveted to each. See Riveted Grating.Rip

Cut along the span of grating. (Usually ripping cross bars)

Glossary

Span of Grating detailSerrated Grating detail

Rivet Centers

The distance center to center of rivets along one bearing bar.Riveted Grating

Grating composed of straight bearing bars and bent reticuline bars (crimp bars) which are joined at their contact points by riveting.

Seal Weld

Welding each bar on both sides, top and bottom. Welded completely. This weld helps prevent water contact to stop corrosion.

Serrated Grating

Grating which the top surfaces of bearing bars are notched – provides non skid footing. See detail below.

Skew Cut

A fabricated diagonal or "S" shape cut.

Span of Grating

The distance between points of grating support and the overall dimension of the bearing bars of grating in this direction. See detail below.

Straight Cut

The cutting of grating along a straight edge. Mostly fi gured when cutting around columns or posts.

Swage-Locked (Swaging) Grating manufactured by altering the cross sectional shape of an aluminum cross bar by applying pressure.

Toe Plate (kick plate)

Banding bar that protrudes above the top of the grating. Its purpose is to prevent items from being “kicked” off the edge of the platform. A 4" projection above the top of the grating is standard. Other projections can be provided when specifi ed.

Transverse

Refers to measurements taken along the width of the grating cross span.

Tread

A panel of grating having carriers and nosing attached by welding, and designed specifi cally to serve as a stair tread.

Welded Grating

Grating in which the bearing bars and the cross bars are joined at all of their intersections by either a resistance weld or conventional hand welding. A resistance weld is obtained by the heat produced by the resistance of the material to the fl ow of electric current causing the material to become plastic. At this point, the pressure on the cross bar is rapidly increased causing the cross bar to penetrate the bearing bar so that they are fused together.
