B-Line 41512N 12 GL Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Steel, 1.5" Channel size, Mill-galvanized, Grip Strut, 12 gauge

The 41512N four diamond plank runs 144 inches long by 9.5 inches wide, with a 1.5 inch channel depth. So one piece covers a 12 foot run in a single length, and you lay planks side by side to build out a wider walking surface, roughly 9.5 inches of tread width gained per plank.

Yes. The 41512N plank is listed as OSHA compliant and is made for safe, sturdy footing where a non-slip surface is required, which is the usual call-out on mechanical platforms, catwalks and rooftop access walks. The four diamond pattern gives the traction; the 1.5 inch channel gives the plank its stiffness between supports.

Mill-galvanized is the finish on the 41512N, which means the steel was galvanized in coil form before fabrication. It handles normal outdoor and damp industrial exposure, but cut ends and punched edges are bare steel and will show surface rust over time. For heavy wash-down, coastal or chemical exposure, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

It is 12 gauge steel, the heavier of the common Grip Strut gauges, and the catalog weight is 5 lb. That means a single 12 foot plank is a one-man carry up a ladder, which is a large part of why crews use plank instead of welded bar grating on retrofit platform work.

Yes, 12 gauge steel plank cuts with a metal-cutting saw or chop saw, and shortening a 144 inch piece to fit a bay is normal practice. Touch up the cut ends with a cold galvanizing compound, since the mill-galvanized coating is applied before fabrication and will not cover a fresh cut.
