B-Line Eaton series Grip Strut three diamond plank, 120" Grating length, 7" Grating width, Steel, 3" Channel size, Mill-galvanized, Grip Strut, 12 gau

Each plank runs 120 inches long by 7 inches wide, with a 3 inch channel depth on the side rails. So one piece gives you a 10 foot run of 7 inch wide tread. For a wider catwalk or platform, plank multiple pieces side by side to build out the width you need.

Yes. The three diamond Grip Strut plank is listed as OSHA compliant, and the diamond-punched openings give the slip resistance that walkway and stair tread duty calls for. It is the plank grating you specify where non-slip footing is required on catwalks, platforms, and access walkways.

The plank is steel with a mill-galvanized finish, meaning the zinc coating was applied to the coil before forming. That handles normal outdoor and damp industrial exposure, but the cut and punched edges are bare steel, so in constant wet, coastal, or chemical wash-down service a hot-dip galvanized or stainless plank is the better call.

5.2 lb for the full 120 inch plank, so it is a one-man carry and easy to get up a ladder or onto a scaffold. Light weight also means less dead load on the supporting structure when you are planking a long catwalk.

The diamond count describes how many rows of diamond openings run across the tread width. Three diamond gives a 7 inch wide walking surface, which is the common single-plank stair tread and narrow catwalk width. Fewer diamonds is a narrower tread, more diamonds is wider. Pick the diamond count by the walking width you need, then match the channel depth to your support spacing, which is 3 inches here.

The order covers the plank itself, model 33012 10 GL. Hold-down clips, saddle clips, bolts, and any support framing are separate line items, so add them to the order when you are fastening plank to bar joist, angle, or channel supports.

It is formed from 12 gauge steel with 3 inch deep side channels. The gauge and channel depth together set how far apart your supports can be, so heavier loading or longer unsupported spans mean adding intermediate stringers rather than changing the plank.
