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. What does “Type 19-4” Mean? Bar grating For applications where extremely slippery conditions prevail, Serrated Tru-Weld offers a superior grip surface to the load bearing bars. Bar grating types are specified by bearing bar spacing followed by cross rod spacing. plain surface 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. serrated surface 6 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). fisher & ludLow > 1-800-268-6277 (Canada) 1-800-334-2047 (USA) www.fisherludlow.com standard mesh bar grating Steel Bar Grating Tru-Weld steel bar grating is the most popular product manufactured by Fisher & Ludlow.

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. stainless steel conversion factors When considering load conditions for stainless steel bar grating, please apply the calculations in the table below to the values shown in the carbon steel load tables on pages 12 and 13.

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. rectangular bar Both Rectangular Bar and I-Bar styles are available in special mesh options. i-bar 24 fisher & ludLow > 1-800-268-6277 (Canada) 1-800-334-2047 (USA) www.fisherludlow.com aluminum standard mesh bar grating aluminum stair treads standard tread detail Aluminum Tread with corrugated angle nosing (Standard) End Plate Width and Hole Pattern Dimensions # of Bars TREAD WIDTH (Type 19-4 Only) “A” dimension (Outer Slot) “B” dimension (Inner Slot) METRIC (mm) IMPERIAL (inches) METRIC (mm) IMPERIAL (inches) METRIC (mm) IMPERIAL (inches) 157 187 217 248 278 308 6 3/16 7 3/8 8 9/16 9 3/4 10 15/16 12 1/8 64 114 114 178 178 178 2 1/2 4 1/2 4 1/2 7 7 7 n/a n/a n/a 114 114 114 n/a n/a n/a 4 1/2 4 1/2 4 1/2 5 6 7 8 9 10 The optional cast aluminum abrasive nosing offers a superior slip resistance on the leading edge of the tread. bar grating aluminum Tread with aluminum abrasive nosing (Special order) Aluminum Standard Mesh Fisholow treads with standard corrugated angle nosing are strong, lightweight, and self-cleaning.

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: How to Order Molded FRP Grating • Corrosion Resistant • Non-Rusting • Fire-Retardant • Non-Conductive • Light Weight • Easy to Install • Unlimited Color Options When ordering or specifying Molded FRP Grating, please confirm: • Type • Resin • Color • Top Surface • Sheet Size Fabrication As with our other grating products, Fisher & Ludlow offers full fabrication services with FRP grating.

The original metal sheet may be expanded as much as 4 times its original length, but is sheared down to stock sheet sizes. expanded metal • 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 Metal 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. Expanded Metal sizes showing the abbreviation “R” are considered to be Raised Expanded Metal. • Strand Width Amount of metal fed under dies to produce one strand. 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. • 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. Flattened Expanded Metal Expanded 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. • 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. Expanded Metal Grating Fisher & 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.
