B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 10

Each plank of the Eaton B-Line 52010 10 GL runs 120 inches long and 11.75 inches wide, with a 2 inch channel depth. To span a walkway wider than 11.75 inches you run planks side by side; the 2 inch channel height is what you need to account for in your support framing and in the finished walking elevation.

The Grip Strut five diamond plank is OSHA compliant, and the diamond-perforated surface is what gets it there: the pierced openings drain liquid and shed debris so footing stays non-slip where a smooth plate would not. That is the reason it gets specified for catwalks, platforms, and equipment access in industrial and utility work.

Mill-galvanized steel is the finish here, which is a pre-galvanized coating applied to the coil before forming. It handles damp interiors, covered exterior platforms, and general industrial exposure. Cut ends and pierced edges are raw steel after fabrication, so for constant weather, washdown, or coastal exposure a hot-dip galvanized-after-fabrication or stainless plank is the better call.

A full 120 inch plank weighs 14.4 lb, so a single worker can carry and set one by hand. That matters on retrofit work where you are passing planks up a ladder or into a tight mechanical space rather than craning in a welded grating panel.

10 gauge is the steel thickness of this plank, the heavier end of the Grip Strut range. Thicker gauge buys you more load capacity at a given support spacing, so heavier gauge is what you move to when your span between supports is long or the traffic includes carts and tooling rather than foot traffic alone. Lighter gauges cost less weight but want closer supports.

The 52010 10 GL is supplied as the plank itself, a 120 by 11.75 inch steel channel section. Hold-down clips, saddle clips, bolts, and any support steel are separate items, so add them to the order if you do not already have them on the job.

Yes, the 120 inch steel plank can be field cut to length with a metal-cutting saw. Because the finish is mill-galvanized rather than galvanized after fabrication, the cut end is bare steel, so hit it with a cold galvanizing compound or zinc-rich paint if the walkway sees any moisture.
