B-Line 31512N 12 GL Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut, 12 gauge

The 31512N 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 choice for catwalks, stair treads, platforms and equipment access decking on industrial sites.

Match four things: the three diamond pierced pattern, the 7 inch plank width, the 1.5 inch channel depth and the 12 gauge steel. The Eaton B-Line part number for this combination in mill-galvanized is 31512N 12 GL. If your existing run is a different width or channel depth, the plank will not sit down on the same supports at the same walking height.

The 31512N is steel with a mill-galvanized finish. Mill galvanizing is applied to the coil before forming, so the cut and pierced edges are bare steel and will show rust first in wet or wash-down service. It is a fit for covered industrial interiors and normal outdoor exposure; for aggressive chemical, coastal or constant-wet conditions, specify a hot-dip galvanized after fabrication or stainless plank instead.

The 31512N is supplied as the plank alone, one model, mill-galvanized. Fasteners, saddle clips, hold-down clips and support steel are ordered separately. Plan on attaching each plank at every support crossing so it cannot shift underfoot.

Yes, 12 gauge steel plank cuts with a metal-cutting saw or band saw, and the 144 inch length is normally field-cut to suit a platform. Because the finish is mill-galvanized, the fresh cut is bare steel, so touch the ends up with a cold galvanizing compound if the walkway sees moisture.
