B-Line Eaton series Grip Strut three diamond plank, 144" Grating length, 7" Grating width, Steel, 3" Channel size, Plain, Grip Strut, 12 gauge steel

The Grip Strut three diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where non-slip surfaces are required. The diamond openings shed liquid, ice, mud and debris, which is why it gets used on mechanical platforms, catwalks and elevated walkways.

It is plain steel, meaning an uncoated mill finish. For outdoor or wash-down areas you would want to paint or coat it, or specify a galvanized version instead. Indoors and dry, plain finish is normally fine.

It is formed from 12 gauge steel, which is the heavier end of the plank range and the common choice for regular foot traffic on maintenance platforms and catwalks. The 3 inch channel depth is what carries the span, so keep your support spacing tight enough for the load you expect.

Order it as Eaton B-Line part number 33012 12 BL, the three diamond plank in 144 inch length, 7 inch width, 12 gauge plain steel with a 3 inch channel.

What ships is the plank itself, 144 inches of 12 gauge plain steel with the 3 inch channel legs. Fasteners, hold-down clips and supporting steel are separate items, so add those to your order along with the planks.

Three diamond plank is a narrow strip, 7 inches wide here, made to be laid in runs for walkways, stair landings and access catwalks where you need traction underfoot. If you need to cover a large open floor area, wide grating panels are the faster way to do it. Plank is the answer for single-file walkways, pipe crossovers and platform edges, and the diamond openings keep the surface from holding water or grease.

The plank is listed at 5.2 lb, so weight is not the limiting factor. The awkward part is the 144 inch length, not the load, and one person can generally handle it. That light weight also helps when you are hanging planks off existing structure rather than building new support.
