B-Line Eaton series Grip Strut two diamond plank, 144" Grating length, 4.75" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut, 10

Yes. The B-Line Grip Strut two diamond plank is listed as OSHA compliant, and the diamond openings are punched to give non-slip footing where safe, sturdy footing is required. That is what makes it usable for elevated walkways, platforms and crossovers in a plant or on a rooftop.

Mill-galvanized steel is the finish here, which is a pre-galvanized coating applied to the sheet before forming. It handles normal indoor industrial and sheltered outdoor exposure. For continuously wet, washdown, coastal or chemically aggressive areas, spec a hot-dip galvanized after fabrication or stainless plank instead, because the sheared edges on mill-galvanized material are left bare.

It is formed from 10 gauge steel, the heavier of the common Grip Strut thicknesses. Within the same 2.5 inch channel depth, a heavier gauge carries more load over a given support spacing, so 10 gauge is the one to specify for foot traffic with tool loads or wider support centers rather than the lighter gauges used for light-duty walk surfaces.

Two diamond refers to the number of diamond rows across the tread face, which sets the walking width. This one gives 4.75 inches of width, which suits stair treads, narrow crossovers and ladder platforms. If you are decking a full walkway or a mezzanine floor, you either run several planks side by side or step up to a wider multi-diamond plank.

The 22510 12 GL is supplied as the plank alone. Attachment hardware, hold-down clips, saddle clips or self-drilling screws to fix the 2.5 inch channel legs to your beams or support angles are ordered separately, so add them to the same order if you are not fabricating your own connection.

Order it as Eaton B-Line part 22510 12 GL. That number breaks down as the 2.5 inch channel, 10 gauge material, 12 foot length and GL for the mill-galvanized finish.
