B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 1.5" Channel size, Mill-galvanized, 14 gauge

Yes. The 31514N 12 GL three 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 what makes it usable for plant walkways, stair treads areas and equipment platforms where inspectors look for slip resistance.

The model to match is 31514N 12 GL: three diamond, 7 inch width, 144 inch length, 14 gauge steel, mill-galvanized, 1.5 inch channel. Ordering by that full designation keeps the channel depth and gauge the same as what is already installed, which matters because a shallower channel changes the support spacing and leaves a step where the two planks meet.

The plank is 14 gauge steel with a mill-galvanized finish, which is a zinc coating applied to the coil before forming. It handles normal indoor industrial and sheltered outdoor exposure. Because the cut and punched edges are bare after fabrication, mill-galvanized is not the choice for constant wet, chemical or coastal exposure; for that you want a hot-dip galvanized after fabrication or stainless grating instead.

The diamond count describes how many rows of serrated diamond openings run across the width. This one is a three diamond plank at 7 inches wide. Fewer diamonds means a narrower plank for a single walk path or a ladder rung; more diamonds means a wider plank that covers more of a platform in one piece with fewer supports to align. Pick the diamond count that matches the walkway width you need, then repeat planks across the span.

No mounting hardware is part of the plank itself. What ships is the formed 144 inch steel plank. Attachment to your beams, angle or channel supports is a separate line item, so add grating clips, saddle washers or weld it down depending on how the framing is detailed.

Yes, it is light for its size. The plank is listed at 3 lb, and being open-formed 14 gauge steel rather than bar grating it is handled by one worker, though 144 inches of length is awkward enough that two people make the lift into place easier on a platform or elevated run.

Yes, the 14 gauge steel plank is cut on site with a chop saw or metal-cutting blade to fit a shorter run than the 144 inch stock length. Cutting exposes bare steel at the new edge, so on a mill-galvanized piece brush on a cold galvanizing compound at the cut to keep rust from creeping.
