B-Line Eaton series Grip Strut three diamond plank, 120" Grating length, 7" Grating width, Steel, 1.5" Channel size, Plain, Grip Strut, 12 gauge

The B-Line Eaton Grip Strut three diamond plank runs 120 inches long and 7 inches wide, with a 1.5 inch channel size and 1.5 inch overall height. That 7 inch width is the walking surface per plank, so for a wider catwalk or platform you lay multiple planks side by side to make up the run.

Yes. The Grip Strut three diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is what makes it a common choice for catwalks, mezzanine access, stair treads and equipment platforms.

Plain finish means bare steel with no coating applied. It is fine for dry interior service, but for outdoor, washdown, or corrosive areas you want a galvanized or stainless version instead of the plain steel plank, because untreated carbon steel will corrode once it is exposed to weather.

The diamond count describes how many rows of the pierced, raised diamond openings run across the walking surface. Three diamond gives the 7 inch width here. If you need a narrower tread, such as a single stair tread run, you would look at a two diamond section; for a wider walkway you either step up the diamond count or lay multiple 7 inch planks side by side.

The 31512 10 BL is the plank only. Hold-down clips, saddle clips, or bolts to secure it to your supporting beams or angle are ordered separately, so budget those into the job along with the number of 120 inch lengths you need.

It is 12 gauge steel, formed into a 1.5 inch channel section. The 12 gauge material combined with the 1.5 inch channel depth is what gives the plank its span capability, so span tables for your load should be checked against the 12 gauge, 1.5 inch profile rather than a lighter gauge product.
