B-Line Eaton series Grip Strut eight diamond plank, 120" Grating length, 18.75" Grating width, Steel, 2" Channel size, Mill-galvanized, 12 gauge

Yes, the eight diamond Grip Strut plank is listed as OSHA compliant, and the serrated diamond openings are what provide the non-slip footing OSHA looks for on walkways and platforms. It is intended for safe, sturdy footing where non-slip surfaces are required.

The plank is 12 gauge steel with a mill-galvanized finish, which is a zinc coating applied to the coil before forming. That suits covered outdoor use, mechanical yards, and general industrial exposure. Note that mill-galvanizing leaves the sheared edges and punched diamonds bare steel, so in constant wet, coastal, or chemical wash-down service those cut edges will be the first thing to rust.

8.9 lb per 10 foot plank. Light enough for one worker to carry up a ladder or hand up to a platform, which is a large part of why formed steel plank gets specified over bar grating on retrofit catwalk work.

The 2 inch figure is the depth of the formed side channels running the length of the plank, and it matches the 2 in product height. Those channels are the structural legs: the plank sits on supports with the channels down, and you fasten through the channel flange to the supporting steel. The 2 inch depth is what sets the span capability, so lay out your support spacing to the load you are carrying.

The diamond count describes how many rows of punched diamond openings run across the width of the plank. Eight diamond gives an 18.75 inch walking width, the wide plank used for full-width catwalks and platform decking. Fewer-diamond planks are narrower and are the ones to use for stair treads, single-file crossovers, and infill strips where 18.75 inches is too wide to fit between supports.

Order Eaton B-Line part 82012 10 GL. That number breaks down to the 2 inch channel eight diamond plank, 10 foot length, GL for mill-galvanized. If you are matching existing decking on a platform, the finish suffix is the part people most often get wrong.

Yes, 12 gauge steel plank is routinely cut on site to suit the opening. Two things to plan for: the cut removes the factory galvanized edge, so touch it up with a cold galvanizing compound, and cutting mid-panel leaves a sheared diamond edge that should land over a support or be trimmed with a nosing where it meets traffic.
