B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 1.5" Channel size, Plain, Grip Strut, 14 gauge st

Yes, the Grip Strut five diamond plank is listed as OSHA compliant. The five diamond pierced and formed surface is what does the work: the raised diamond openings shed water, oil, mud and light debris and give slip resistance in all directions, which is why it gets used on catwalks, mezzanine walkways, stair treads and equipment platforms where sure footing is required.

Plain means bare, uncoated steel with no galvanizing or paint applied. That's fine for dry interior use, but bare steel will corrode outdoors or in a washdown or chemical area, so for exterior platforms you want a galvanized or coated version of the same plank instead. Plain stock is also the right pick if you plan to field cut and then paint or powder coat the assembly yourself.

The 14 gauge steel plank with a 1.5 inch formed channel is the standard choice for pedestrian traffic: maintenance catwalks, access platforms, stair treads and ladder landings. It carries foot traffic and light tool loads between supports. If you're rolling carts, staging pallets, or putting wheeled equipment on it, that's a job for heavier bar grating or a deeper channel plank, not a 1.5 inch 14 gauge tread section.

Yes. It's 14 gauge plain steel, so it cuts with a circular saw and metal blade, chop saw or plasma. Since the finish is plain and uncoated, there's no galvanizing to burn off at the cut, but the fresh edge and the whole plank should be primed or painted if the installation sees any moisture.
