B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 12 ga

The Grip Strut four diamond plank runs 120 inches long by 9.5 inches wide, with a 2 inch channel height. That 9.5 inch width is a single plank run, so for a wider catwalk or platform you set multiple planks side by side. The 2 inch channel depth is what you have to account for in your support spacing and finished walking elevation.

Yes. The B-Line Grip Strut four diamond plank is listed as OSHA compliant, and the serrated diamond openings are made for safe, sturdy footing anywhere non-slip walking surface is required, catwalks, mezzanine platforms, stair treads and equipment access. The openings also shed water, oil and debris rather than holding it on the surface.

Mill-galvanized steel is a pre-galvanized coating applied to the sheet before forming, so the cut and formed edges are bare steel. It handles normal indoor industrial and sheltered outdoor duty. For constant wetness, chemical exposure or coastal air, you want a hot-dip galvanized after fabrication or stainless plank instead, where every cut edge is covered.

12 gauge is the thickest of the common Grip Strut material gauges, so this plank is the heavy-duty option, chosen when you need longer clear spans between supports or higher foot and equipment loading. Lighter gauges are thinner steel and want closer support spacing. If your drawing calls out a gauge, match it, because span tables are gauge specific.

Order it as Eaton B-Line 42012 10 GL. That is the four diamond plank, 12 gauge steel, 9.5 inch grating width, 120 inch length, 2 inch channel, mill-galvanized. Width, gauge and finish all change the number, so quote the full designation when you order for a job.

The 42012 10 GL is the plank only. Hold-down clips, saddle clips or weld attachment and the supporting steel are all separate, so budget those in when you take off a catwalk or platform job. Planks are typically clipped or welded to the supporting members at each bearing point.

Yes, plank is routinely cut to length on site for openings and odd runs. Keep in mind the finish here is mill-galvanized, so any cut leaves exposed steel. Touch cut ends with a cold galvanizing compound if the walkway sees moisture.
