B-Line Eaton series Grip Strut six diamond plank, 120" Grating length, 27.75" Grating width, Steel, 2" Channel size, Plain, Grip Strut, 10 gauge

Yes, the Eaton B-Line Grip Strut six diamond plank is listed as OSHA compliant, and the serrated diamond openings are there to give non-slip footing where safe, sturdy traction is required. That is the point of the product for mechanical rooms, rooftop walkways, stair treads and equipment platforms.

Plain is the finish here, meaning uncoated steel with no galvanizing or paint applied. Indoors in a dry mechanical or electrical room that is normally fine as-is. Outdoors, on a roof, or anywhere washdown or condensation is a factor, plan on coating it or specify a galvanized plank instead, because bare 10 gauge steel will rust.

This plank is formed from 10 gauge steel, the heavier end of the Grip Strut range, and the 2 inch channel depth is what carries load between supports. Heavier gauge and deeper channel means longer allowable spans and higher foot and equipment loads. For light-duty catwalks with closely spaced supports a thinner gauge plank does the job; for longer unsupported spans or rolling loads, stay with the 10 gauge.

Yes, the plank is 10 gauge formed steel and gets field cut with a metal chop saw or cutoff wheel to suit the opening. Since the finish is plain uncoated steel, a cut edge is the same bare material as the rest of the plank, so treat cut ends the same way you treat the surface if corrosion is a concern.
