B-Line Eaton series Grip Strut two diamond plank, 120" Grating length, 4.75" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 14 ga

Each plank of the Eaton B-Line Grip Strut two diamond plank runs 120 inches long and 4.75 inches wide, with a 2 inch channel depth. That narrow 4.75 inch width is why it is called a plank rather than grating: you lay two or more side by side to make up the walking width you need, and cut or order lengths to suit the span. Model 22014 10 GL.

Yes. The Grip Strut two diamond plank is listed as OSHA compliant, and the diamond-shaped openings are punched to give slip resistance in oil, water, ice, and mud. That is the reason it gets specified for catwalks, platform decking, and stair treads where a smooth plate would be a fall hazard.

Match four things: plank width, channel depth, gauge, and finish. This one is 4.75 inches wide, 2 inch channel, 14 gauge, mill-galvanized steel, sold as model 22014 10 GL in a 120 inch length. If your existing run is a deeper channel or a wider grating section, the new piece will sit at a different height and the walking surface will not come out flush.

The plank is steel with a mill-galvanized finish, which is zinc applied to the coil before forming. That handles normal indoor, damp, and sheltered outdoor duty, but the cut ends and punched edges are bare steel after fabrication. For continuous wash-down, coastal, or corrosive chemical exposure, specify a hot-dip galvanized-after-fabrication or stainless plank instead of mill-galvanized.

Gauge sets how much load the plank carries between supports. This one is 14 gauge steel in a 2 inch channel depth, which is the common general-duty pedestrian choice. If your support spacing is wide or the platform sees carts, drums, or equipment loads, step up to a heavier gauge or a deeper channel rather than tightening the span on 14 gauge.

The two diamond plank is a 4.75 inch wide walking section, which is narrower than a finished stair tread. Planks are typically ganged to build up tread or walkway width, and they are not supplied with tread end plates or carrier angles. For a stair, plan on multiple planks per tread plus your own support angles and fasteners, or order a purpose-made Grip Strut stair tread with end plates already attached.

No. What ships is the formed steel plank itself, 120 inches long with 2 inch channel legs. You supply the support framing and the hold-down hardware, normally saddle clips or self-drilling screws through the channel leg into the support member. Budget for those separately when you price the job.

Light enough for one person. The 120 inch plank is 14 gauge steel and is listed at 2.6 lb, so a crew can carry and set several runs by hand without a lift. That is part of the appeal over checkered plate decking on elevated platforms.
