B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 10 gau

It is a 12 foot plank: 144 inches long, 7 inches wide, with a 2 inch channel size and 2 inch overall height. Formed from 10 gauge steel and weighing 9.5 lb per plank. The 2 inch channel depth is the turned-down side leg, so the walking surface sits 2 inches above whatever framing you set it on.

The 32010 12 GL plank is listed as OSHA compliant. The pierced three diamond pattern gives a non-slip surface for footing where slip resistance is required, which is what it is made for on catwalks, platforms and equipment access runs.

Mill-galvanized is the standard finish on this plank: the steel is galvanized before forming, so the cut and pierced edges are left bare. That is fine for general industrial interiors and sheltered exterior use, but in a constantly wet, wash-down or corrosive environment you want a hot-dip galvanized-after-fabrication or stainless plank instead, where every edge is coated.

A plank like the 32010 12 GL is a single formed channel, 7 inches wide with a 2 inch deep leg on each side, that you lay in parallel runs and fasten individually. Bar grating comes as a wide welded panel dropped in as one piece. Planks are lighter to handle, at 9.5 lb each here, and easier to fit around pipe penetrations and irregular framing; grating panels cover large open areas in fewer pieces.

Yes, the 10 gauge steel plank can be cut to length in the field with a metal-cutting saw. Because the finish is mill-galvanized, cut ends are raw steel, so brush on a cold galvanizing compound if the run sees any moisture. Ordering the 144 inch length and trimming is normal practice when spans do not land on a stock size.
