B-Line Eaton series Grip Strut three diamond plank, 120" Grating length, 7" Grating width, Steel, 2" Channel size, Plain, Grip Strut, 14 gauge

Yes. The three diamond plank is listed as OSHA compliant, and the perforated diamond surface is what earns it: the punched openings shed water, oil, mud and ice instead of holding them, so the footing stays slip resistant. That is why it gets specified for catwalks, stair treads, platforms and equipment access in plants and on rooftops.

Plain means bare, uncoated steel with no galvanizing or paint. Indoors and in dry conditions that is fine. For exterior, washdown, or corrosive areas, plan on field painting or specify a galvanized or stainless Grip Strut plank instead, because bare 14 gauge steel will rust once it is wet.

The diamond count tells you how wide the walking surface is. This three diamond version gives a 7 inch wide plank, which suits a single narrow access run or ganging up into a wider catwalk. Narrower two diamond or single diamond sections are the ones to use for stair treads and tight pipe rack access, while wider four and five diamond planks cut the number of pieces on a full width platform.

The plank is formed with 2 inch deep channel legs on each side, giving a 2 inch overall height. The legs bear on the supporting members and the diamond surface sits flush at the top of the 2 inch profile, so set your support elevation 2 inches below finished walking height. Planks are field drilled and bolted or clipped to the supports; no fasteners come with the plank.

Yes. At 14 gauge steel it cuts with a chop saw or abrasive blade, so a 120 inch plank can be trimmed to fit a short bay or notched around pipe and conduit penetrations. Cut ends on plain, uncoated steel should be primed or painted, since there is no galvanized coating to protect them.
