15 Aluminum Plank 13 Plank Punch/Pattern Availability Aluminum plank grating is available unpunched or with a variety of punch/patterns as shown below. Rectangular or square punched holes are most commonly used for water and waste treatment plants and in marine applications, while the round holes find application primarily in the marine market. The surface of plank grating can be specified as plain or with one of two styles of upsets (OGI or WACO) designed to promote a slip resistant walkway, especially in the presence of moisture, oil or other spilled substances. Punch/Pattern Availability Section Availability Note: Plank is also available in a Dog-Bone punch pattern by special request. Contact Robertson Grating Products.

16 14 Aluminum Plank Plank Load Tables * Based on punched plank Note: Grating for spans to the left of the heavy line have a deflection less than 1/4" for uniform loads of 100 lbs./sq. ft. This is the maximum deflection to afford pedestrian comfort and can be exceeded for other types of load at the discretion of the engineer. The actual Ped (pedestrian) Span under this condition is shown above for each size of grating. This grating conforms to MIL-G (SHIPS)

17 RGP Molded Fiberglass Grating 15 Molded Fiberglass Grating RGP Molded Fiberglass Grating is available in both high-quality polyester (standard) and vinyl ester resin for harsher chemical applications. Our high-traction grit surface is standard, but meniscus (concave/non-grit) is available upon request. Molded comes standard in gray and green. Other colors such as yellow and orange are available upon request. Contact Robertson Grating Products for details. Depth 1" 1-1/2" 2" Sq.

S.A.E. Grade 5, lightly oiled), washers and hex nuts. Kit joins continuous sections together in run over clear spans to act as one continuous unit. Any combination of 12 and 10 ft. planks can be joined with splice plate package. Splice Place Package 7" Part No. SP-10DU-7 Four 1/2" dia. holes in each corner of up-turned kickplate, two 8-hole 10 ga. 4" x 7" splice plates, with 16 ea. 7/16" x 1-1/4" bolts, washers and hex nuts. Each corner of up-turned kickplate should have four 1/2" dia. holes. Kit joins continuous sections together in a run only over supports. Recommended bolt torque: 55 ft./lb. minimum. Walkway Splice plates are also available for Heavy Duty Grip-Strut contact RGP for details. Recommended clearance STEEL: 1/4" minimum is recommended at perimeter and 3/8" maximum at end joints. maximum between panels is 1/4". 1/8" is generally used. CONCRETE: Concrete form deflection calls for slightly greater perimeter clearance. 1/2" is recommended. Maximum between panels 1/4". Bearing Surfaces Recommended minimum bearing 1-1/2". Surfaces supporting Grip-Strut must be smooth and level to insure that adjoining sections provide a safe, even walking surface. Permanent Installation Grip-Strut is easily welded to supports for permanent installations. Channels are quickly welded together between supports to provide uniform deflection in adjacent panels. For welded attachment, secure side channels to supports by fusion welding with 1/8" fillet welds. Weld adjacent planks together with 1/8" fillet welds 1" long, 24" o.c. staggered top and bottom. Install Grip-Strut according to details as shown on individual job drawings or as follows: 1.) Single width applications: Utilizing the anchoring device or weldings, attach Grip-Strut plank at every point of contact with supporting structure around perimeter of plank. 2.) Multiple width applications: Utilizing the Grip-Strut anchoring device or welding as recommended by A.I.S.I. attach plank around the perimeter at each point of contact with supporting structure. In field, attach plank to supporting structure with a minimum of one attachment at each end of plank on alternate sides. When span exceeds 8 ft., weld or bolt side channels of adjacent planks together at midpoint of span. (When spans exceed 6 ft., consider similar treatment.)

PERF-O GRIP Grating Splice Plate Kits Surface Splice Plate Kits Walkway Splice Plate Kits Walkway Splice Plates provide continuity when multiple lengths of PERF-O GRIP are desired. Connections are reinforced with the addition of splice plates attached to side channels. POG-WS-30 for 24" and 30" wide walkway Each kit includes 2 splice plates and 32 each of the following hardware: 1/2" x 1-1/4" hex bolts, 1/2" 13 hex nuts and 1/2' flat washers. As width increases, grating surface performance becomes more critical. Thus, for PERF-O GRIP product widths greater than 12", use of grating splice kit is recommended to mechanically join butt ends of plank sections.
