tru-weld® bar grating

Tru-Weld bar grating is forge-welded, a system in which Fisher & Ludlow was a pioneer. In this process the bearing bars and cross rods are permanently forged together by heat and pressure into a single unit construction, resulting in greater strength per pound than mechanical assembly methods. The twisted cross rods provide a non-slip walking surface.

For applications where extremely slippery conditions prevail, Serrated Tru-Weld offers a superior grip surface to the load bearing bars.

What does “Type 19-4” Mean?

Bar grating types are specified by bearing bar spacing followed by cross rod spacing.

In imperial measurements, bearing bar spacing is described in sixteenths of an inch. Therefore, Type 19 has bearing bar centers at 19/16 of an inch (or 1 3/16”). Type 15 has bearing bar centers at 15/16”. Type 11 is at 11/16” etc. The second number after the dash in the Type designation refers to the cross rod spacing. Cross rods are available in either 4” (standard) or 2” (special) spacings.

All bar grating Types may also be described in metric units. Again, the first number represents the bearing bar spacing on centers and the second number represents the cross rod spacing, both units measured in millimeters. Therefore, Type 30-102 Metric equals bearing bars at 30mm centers and cross rods at 102mm centers. This is the metric equivalent of Type 19-4.

Note: Although the special 2” (50mm) cross rod spacing does allow for less open space on the grating surface, it does not affect the load rating of the grating. The most economical and readily available choice for bar grating selection is Type 19-4 (Type 30-102 Metric).

Loads and deflections given in this table are theoretical and are based on a maximum allowable fibre stress of 18,000 P.S.I.


type 19

IMPERIAL LEGEND U = Safe Uniform Load (lbs./ft.2)C = Safe Concentrated Load (lbs./foot of grating width) D = Deflection (inches)

Spans and loads in the pink shaded area exceed a deflection of 1/4” for uniform loads of 100 lbs/sq. ft. Experience has shown that 1/4” deflection is the maximum deflection to give pedestrian comfort, but can be exceeded for other types of loads at the discretion of the engineer.

tru-weld stainless steel bar grating

Tru-Weld Stainless Steel Bar Grating provides a long-term durable grating solution for caustic atmospheres where corrosion resistance and minimum carbide precipitation are important considerations. Typical applications include stairs and platforms within chemical production and storage, food processing plants, and water and wastewater treatment facilities. Your choice of 304, 304L, 316, or 316L Stainless Steel grades are available.

Heat from the Electroforge welding process discolors the surface of the stainless steel in the weld area. For this reason, Tru-Weld Stainless Steel Bar Grating is best suited for industrial uses where cosmetic appearance is not a factor.

special mesh information

tru-weld special mesh bar grating

Tru-Weld Special Mesh Bar Grating offer a variety of close or wide space mesh options to suit specific aesthetic or functional bar spacing requirements.

As with Tru-Weld Standard Mesh Bar Grating, Special Mesh Bar Grating may be ordered with either plain or serrated bearing bars. Similarly, panels are manufactured with a standard 4” cross rod spacing but 2” cross rod spacing is available.

Close MeshAdvantages of the close mesh grating style include greatly increased load bearing capabilities and prevention of fall through by dangerous objects such as heavy tools or equipment accidentally dropped from above.

Wide MeshWide mesh grating options are designed for applications requiring additional openness of bar grating to minimize buildup of snow, ice, or other debris.

Available in most 1/8” and 3/16” Steel and Stainless Steel bar sizes and select Heavy Duty bar sizes.

*Special Mesh Bar Grating is a non-stocked specialty item. For the most cost effective and readily available bar grating option, choose Standard Mesh Type 19-4 (Type 30-102 Metric).

railroad grating

Tru-Weld Steel Railroad Grating is special wide mesh Type 26-4 (Type 41-102 Metric) with bearing bars supplied serrated for additional safety. It was originally designed specifically for use as brake steps, running boards, walkways, and platforms on railcars and locomotives. Railroad Grating is supplied as standard AAR (Association of American Railroads) approved welded bar grating with bar spacing at 1 5/8” centers and cross rods at 4” centers.

heavy duty information

heavy-duty steel bar grating

Steel Bar Grating with bearing bars thicker than 3/16” is considered to be “Heavy Duty” and carries the designation prefix “Type HD”. Available bar thicknesses are 1/4”, 5/16”, and 3/8” in either a plain or serrated surface. Standard depths range from 1” up to 4”, although larger sizes are available upon request.

Tru-Weld Heavy Duty Steel Bar Grating is commonly used for floor trench and sump covers exposed to heavy equipment traffic. It is used extensively throughout mining, power generation, highways, airfields, and on truck terminal loading docks and ramps. It is suitable for large single span conditions or where grating must support extreme loads.

aluminum information

fisholow® rectangular and i-bar grating

Fisholow Aluminum Bar Gratings employ a unique interlocking system that joins the bearing bars and cross rods together in panels of exceptional rigidity and strength. Lightweight, corrosion-resistant, non-sparking alloys are ideal for pedestrian platforms in chemical, petroleum, and food processing plants. Fisholow gratings is recommended in most water and waste water treatment facilities and is becoming increasingly popular for use in architectural building designs.

Fisholow Aluminum Bar Grating is available in two bar profiles: Rectangular Bar and I-bar. Similar to Tru-Weld Steel Bar Grating, Fisholow Rectangular Bar Grating is offered with a plain or serrated surface. Fisholow I-Bar Grating produces exceptional load ratings at a fraction of the weight of its rectangular counterpart, and is designed with a slip resistant corrugated surface on the top of each I-bar.

Both Rectangular Bar and I-Bar styles are available in special mesh options.

aluminum stair treads

aluminum tread with corrugated angle nosing (standard)

Fisholow treads with standard corrugated angle nosing are strong, lightweight, and self-cleaning. They are ideal for applications requiring corrosion resistance, non-sparking, and rust proof grating. The corrugated angle nosing insures maximum visibility and underfoot safety where needed most.

aluminum tread with aluminum abrasive nosing (special order)

The optional cast aluminum abrasive nosing offers a superior slip resistance on the leading edge of the tread.


how to order

When ordering or specifying Fisholow treads, please confirm:

• Type, bar size, and surface of grating• Type of nosing – corrugated angle nosing is standard• Width of tread• Length of tread• Number of treads• Shipping and tagging instructions

Example: Fisher & Ludlow Fisholow treads, c/w 1 1/4” x 3/16” serrated rectangular-bar aluminum bar grating, corrugated angle nosing and standard end plates, 12 1/8” wide x 36” long, 150 pcs, tagged “Project ABC”.

grip span walkway channel

Grip Span Walkway channels offer the same slip resistant properties and self-cleaning advantages of other Grip Span planks with the added feature of having built in kick-plates along both sides of the channel length. The 5” toe boards are integral parts of the channel and prevent tools and other materials from falling over the edge of a catwalk.

molded frp information

molded fibreglass reinforced plastic (frp) grating

Molded Fiberglass Reinforced Plastic (FRP) Grating is manufactured in an open, heated mold. Continuous E-glass fibers are interwoven in alternating layers while being completely wetted out with thermosetting resin systems. This continuous process produces an integral, one piece construction which provides resilience and bi-directional strength. Although the concave profile of standard plain surface Molded FRP Grating provides excellent anti-skid properties, an integral grit surface can be supplied for additional slip resistance. Other benefits include:

• Corrosion Resistant• Non-Rusting• Fire-Retardant• Non-Conductive• Light Weight• Easy to Install• Unlimited Color Options

fabrication

As with our other grating products, Fisher & Ludlow offers full fabrication services with FRP grating. We can also supply a variety of FRP structural shapes that may be associated with an FRP grating project. Please call us to discuss any of your custom platform and stair requirements.

molded frp grating resin systems

how to order molded frp grating

When ordering or specifying Molded FRP Grating, please confirm:

• Type• Resin• Color• Top Surface• Sheet Size

Example: Fisher & Ludlow Molded FRP 1 1/2” deep square mesh, AN (Architectural Grade, Non Fire Retardant), dark grey, grit top, 4’ x 12’ sheets

installation

FRP grating sheet size and lightweight construction permit simple and economical installation. Fasteners, supports and hold-down clips permit total flexibility in achieving the desired configuration of the final installation.

Conventional hand tools such as a hack saw, sabre saw, band saw or disc saw with metal cutting blade can be used to cut grating on-site and to cut around special openings as required. Cut ends should be treated with Edge Sealing Kits.

bar grating fasteners

Type D Saddle Clip (complete with stainless steel self tapping screw)

Our most common and cost-effective fastening method. Simply pre-drill a hole into the supporting member and drive in the self-tapping screw. Designed for use with Tru-Weld Type 19 and Type 15 bar grating only (in 1/8” and 3/16” bar sizes).

Available in standard galvanized or bare steel and stainless steel options.

Type D Saddle Clip (complete with nut, bolt, and bottom clamp)

This combination allows for fastening grating without drilling into the supports. The Type D Saddle Clip holds the grating from the top as the bottom clamp is tightened under the flange of the supporting member. Designed for use with Tru-Weld Type 19 and Type 15 bar grating only (in 1/8” and 3/16” bar sizes).


Type D Saddle Clip (complete with C-clamp and bolt)

Eliminates the need to drill supports or have access beneath the grating during installation. The C-clamp slides between the bearing bars to clamp the flange of the supporting member and is tightened from above using a hex-driver. For use with Tru-Weld Type 19 and Type 15 bar grating only (in 1/8” and 3/16” bar sizes).


Type B Clamping Bolt, Nut, and Bottom Clamp

For close mesh Type 11 and Type 9.5 grating, a square collared clamping bolt can be inserted directly between the ends of the bearing bars and fitted through a bottom clamp. The rounded bolt head rests directly on the bearing bars eliminating the need for a top saddle clip.

Available by special order in bare steel, galvanized, and stainless steel.

expanded metal

Expanded Metal is manufactured from carbon steel or aluminum sheets that are simultaneously slit and stretched to create diamond shaped openings. The original metal sheet may be expanded as much as 4 times its original length, but is sheared down to stock sheet sizes.

• Light weight and strength make expanded metal an extremely versatile material

• Ideal for partitions, enclosures, barriers, filters, walkways, grilles, and machine guards

• Available in Raised or Flattened styles in a variety of gauges and opening sizes to fit any application

• Standard sheets in stock for immediate shipment• Custom Shearing available

Raised Expanded MetalExpanded Metal sizes showing the abbreviation “R” are considered to be Raised Expanded Metal.

Raised Expanded Metal is a finished product as it comes from the press. The strands and bonds are set at a uniform angle to the plane of the sheet. This gives added strength and rigidity, as well as a skid resistant surface.

Flattened Expanded MetalExpanded Metal sizes with the abbreviation “F” are designated Flattened Expanded Metal.

Flattened Expanded Metal has been cold rolled after the expansion process to provide a smooth, flat, and level sheet. The flattening process reduces the original gauge of the base metal and the strand width increases slightly.

Expanded Metal GratingFisher & Ludlow manufactures two sizes of Expanded Metal Grating, 3 lb. Grating and 4 lb. Grating. This style of Raised Expanded Metal is produced from heavier gauge carbon steel plates. Expanded Metal Grating is ideal for pedestrian traffic and applications requiring heavier loads or larger openings than conventional expanded metal options.

Expanded Metal Terminology• short way of design (swd)

Nominal dimension

• long way of design (lwd) Nominal dimension – When referring to a sheet size the SWD is always referred to before the LWD. For example a “4 x 8 sheet” is 4 feet in the SWD direction and 8 feet in the LWD direction.

• short way of opening (swo)

• long way of opening (lwo)

• strand thickness Gauge thickness of the original base metal sheet prior to expanding.

• strand width Amount of metal fed under dies to produce one strand.

• bond shearing Cutting expanded metal to size with the shear line falling through the bonds. The result is an edge configuration of all closed diamonds. For bond shearing the resultant dimensions must be in a multiple of the full diamond dimensions.

• random shearing The shear line falls at random points on the diamond mesh pattern. Edges are open and diamonds are not matched. Random shearing is necessary when the required overall dimensions are not a multiple of the full diamond dimensions.
