B-Line Eaton series Grip Strut ten diamond plank, 144" Grating length, 24" Grating width, Steel, 4.5" Channel size, Mill-galvanized, 12 gauge

Yes, the ten diamond plank is listed as OSHA compliant, and the diamond-pierced surface is intended for safe, sturdy footing where non-slip is required. That is what makes it a common pick for elevated catwalks, mezzanine walkways, and equipment platforms in industrial facilities.

The plank is 12 gauge steel with a mill-galvanized finish, which is a zinc coating applied to the sheet before forming. That handles normal outdoor exposure and damp interior areas. In heavy washdown, coastal salt air, or chemical service, the cut and formed edges are where mill-galvanized gives up first, so a hot-dip galvanized or stainless grating is the better call there.

The diamond count describes how many rows of pierced diamonds run across the walking surface, which sets the width. The ten diamond version is 24 inches wide, sized for a full two-foot walkway or platform panel. Narrower plank counts are what you use for stair treads, ladder rungs, and single-file access runs where 24 inches of width will not fit between rails.

Fasteners are not part of the plank. You order the grating on its own and add hold-down clips, saddle clips, or weld it to the supporting steel depending on how your structure is built. Budget the attachment hardware separately when you price the run, along with any toe board or handrail the walkway needs.

Field cutting a 144 inch plank to length is normal practice on platform work. Keep in mind the mill-galvanized coating is applied to the sheet before forming, so any cut you make exposes bare steel at the end. Touch those edges up with a cold galvanizing compound if the walkway sees weather or moisture.
