B-Line 52510 12 GL Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut, 10 gauge

Yes. The Eaton B-Line 52510 12 GL five diamond plank is listed as OSHA compliant, and the diamond-pierced surface is what gets you there: it is made for safe, sturdy footing where non-slip is required. That is the reason it goes on catwalks, mezzanine walkways, stair treads and equipment platforms rather than plain plate.

Mill-galvanized is the finish on the 52510 12 GL, meaning the steel is galvanized before forming, so the cut ends and the pierced diamond edges are left as bare steel. It suits covered exterior work, mechanical rooms and industrial plants. For constant wet exposure, coastal air or chemical wash-down, look for a hot-dip galvanized-after-fabrication or stainless plank instead, since those cover the sheared edges.

Each 144 inch plank weighs 14.8 pounds, so one worker can carry and set it by hand. That is a real advantage over bar grating of the same span when you are installing on a scissor lift or passing material up to a mezzanine, and it keeps the dead load on your supporting steel low when you are decking a long run.

The diamond count describes how many rows of pierced diamonds run across the width of the plank, so it sets the walking width. Five diamond gives the 11.75 inch width on the 52510 12 GL, which is a full walkway plank. Narrower two, three or four diamond channels cover less width per piece and are used for stair treads, single-file crossovers and narrow pipe-rack walkways. Pick by the finished width you need and how many planks you want to lay side by side.

It is formed from 10 gauge steel, the heaviest of the common Grip Strut gauges, with a 2.5 inch channel depth giving it its stiffness. Heavier gauge and deeper channel both buy you longer clear spans between supports. Set your support spacing from Eaton's load table for 10 gauge, 2.5 inch channel material against the live load and concentrated load your job calls for.

The 52510 12 GL is the plank only, ordered as the single model 52510 12 GL. Attachment hardware, hold-down clips, saddle clips or self-drilling fasteners are separate and need to be ordered to suit your supporting steel. Decide up front whether you are welding, bolting through the channel flange, or clipping, since that changes what you add to the order.

Yes, these steel planks are routinely field cut to length with a metal-cutting saw. Because the finish is mill-galvanized, the cut end is bare steel, so hit it with a cold galvanizing compound if the run is exposed to weather. Cutting is also how most crews handle a 144 inch stock length that has to land on an odd bay spacing.
