B-Line Eaton series Grip Strut two diamond plank, 144" Grating length, 4.75" Grating width, Steel, 2.5" Channel size, Plain, Grip Strut, 14 gauge

Yes, the Grip Strut two diamond plank is listed as OSHA compliant, and it is intended for safe, sturdy footing where non-slip surface is required. That makes it usable for elevated walkways, catwalks, stair treads and equipment platforms where a slip resistant surface is called for.

It is formed from 14 gauge steel with a plain finish, meaning no galvanizing or paint applied. Plain steel is fine for dry interior service, but for outdoor, washdown or corrosive areas you should specify a galvanized or coated version instead, or field coat it before installation.

Two diamond refers to the number of diamond openings across the walking surface, which is why this one is 4.75 inches wide. It is the plank you use for narrow runs: single stair treads, crossovers, ladder rungs, pipe bridges, or ganged together to make up a wider deck. If you need a full platform in one piece, a wider multi-diamond panel covers more area with fewer support points.

The plank has a 2.5 inch channel size and a 2.5 inch overall height, so the formed legs drop 2.5 inches below the walking surface. Allow for that depth over your supporting steel when you are setting finished walking elevation, and space supports so the ends land on structure.

The plank is listed at 2.8 lb, so weight is not the issue, but a 144 inch length is awkward for one person to handle up a ladder or through a tight equipment room. Plan on two hands or a second set for staging long runs.
