B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 3" Channel size, Plain, Grip Strut, 10 gauge

The plank is 144 inches long and 7 inches wide, with a 3 inch channel depth. That 12 foot length lets it span a walkway or platform run in one piece, and the 7 inch width means you lay multiple planks side by side to build up a wider walking surface.

Yes. The Grip Strut three diamond plank is listed as OSHA compliant, and the diamond openings give the non-slip footing OSHA walking surfaces call for. It is the surface used where safe, sturdy footing is required and slipping is the hazard being controlled.

Plain means bare steel with no galvanizing or coating applied. That is fine for dry indoor mechanical rooms, catwalks and platforms, but bare steel will corrode in wet or outdoor service, so for exterior decks, wash-down areas or coastal sites you want a galvanized or pre-galvanized version of the same 3 inch channel plank instead of the plain one.

Each 144 inch plank weighs 10.5 lb, so a single worker can carry one up a ladder or across a roof without a lift. That light weight per piece is a large part of why formed steel plank gets used in place of heavier bar grating on retrofit catwalks.

It is formed from 10 gauge steel, the heavier of the common Grip Strut gauges, and the 3 inch channel depth is what carries the load between supports. For pedestrian traffic on catwalks, platforms and mechanical access walkways that combination is the usual specification. Support spacing still governs, so lay out your stringers to the span your design calls for.

Yes, it is formed 10 gauge steel plank and installers regularly cut it to fit the opening with a metal-cutting saw. Because the finish is plain uncoated steel, a field cut needs no touch-up for appearance, but any cut edge on bare steel should be primed or painted if the area sees moisture.
