B-Line 82510 12 GL Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut, 10 gauge

The 82510 12 GL plank runs 144 inches long by 18.75 inches wide, with a 2.5 inch channel depth (the product height is also listed at 2.5 inches). So one plank spans a 12 foot run and covers just over 18-3/4 inches of walking width. For a wider platform, planks are laid side by side until the walkway width is made up.

Yes. The 82510 12 GL eight diamond plank is listed as OSHA compliant, and the serrated diamond openings are there to give footing where a non-slip surface is required, in the direction of travel and across it. That is the normal reason it gets specified over plain plate or bar grating on catwalks, mezzanine walkways, stair treads and equipment platforms.

Mill-galvanized steel is the finish on the 82510 12 GL. That is zinc applied to the coil before forming, so the cut ends and punched edges are bare steel. It holds up fine in covered, dry industrial interiors. For sustained outdoor exposure, salt air, or regular wash-down, a hot-dip galvanized after fabrication or stainless plank is the better call, since the sheared edges on a mill-galvanized part are where rust starts.

It is formed from 10 gauge steel, the heavier end of the Grip Strut plank range. Gauge and the 2.5 inch channel depth together set how far apart your supports can be for a given load, so pull the load table for 10 gauge, 2.5 inch plank and lay out your bearers to that span rather than assuming the full 144 inch length is an unsupported span.

The 82510 12 GL is the plank only, at 144 by 18.75 inches. Hold-down clips, saddle washers, self-drilling screws or weld attachment are specified separately based on whether your bearers are steel beam, angle or channel. Count on ordering attachment hardware as a separate line when you price the walkway.

Order Eaton B-Line part number 82510 12 GL. The suffix reads directly: 12 for the 144 inch (12 foot) length and GL for the mill-galvanized finish, on the eight diamond, 2.5 inch channel, 10 gauge steel plank.

Yes, formed steel plank is routinely cut on site with a saw or torch to fit a run. Two things to plan for on the 82510 12 GL: the cut has to land on a bearer so the channel ends are supported, and cutting exposes bare steel because the mill-galvanized finish is applied to the coil, not after forming. Touch the cut ends with cold galvanizing compound.
