B-Line Eaton series Grip Strut eight diamond plank, 144" Grating length, 18.75" Grating width, Steel, 3" Channel size, Mill-galvanized, Grip Strut, 12

The eight diamond plank runs 144 inches long and 18.75 inches wide, with a 3 inch channel depth. So one plank spans a 12 foot run and covers just over a foot and a half of walking width. If your platform is wider, plank them side by side; if the run is longer than 12 feet, you need intermediate support under the joints.

Yes, the Grip Strut eight diamond plank is listed as OSHA compliant, and the diamond-punched surface is made for safe, sturdy footing where non-slip is required. That is what puts it on catwalks, mezzanines, stair treads and equipment platforms rather than plain sheet.

Mill-galvanized steel is the standard indoor and sheltered-outdoor finish. The zinc goes on the coil before forming, so the punched diamond edges and cut ends are raw steel and will surface rust in constant wet, salt spray or chemical wash-down. For dry plants, utility catwalks and covered platforms it is the normal choice. For sustained wet exposure, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

Each 144 inch plank is listed at 9.6 lb, so two people can carry and set one by hand without a lift. It is formed from 12 gauge steel, the heavier end of the plank range, which is what lets it span between supports rather than sit on a solid deck.

The 3 inch channel size means the plank has formed side channels that act as its own structural beams, so it carries load between supports on its own. A flat grating panel or a plain diamond plate needs a framed bearing on all sides. If you are decking an open frame with beams every few feet, the channel plank is the simpler install; if you are covering a continuous solid substructure, flat product is usually enough.

That is Eaton B-Line model 83012 12 GL: the eight diamond plank, 18.75 inch grating width, 144 inch length, 3 inch channel, 12 gauge steel, mill-galvanized. The eight diamond count is what sets the walking width, so quote that number if you are matching existing planks already on the platform.

Yes, the 12 gauge steel plank can be field cut to length with a metal chop saw or torch, and cutting does not affect the diamond pattern underfoot. Keep in mind the mill-galvanized finish is applied to the coil, so any cut end is bare steel and should be touched up with a cold galvanizing compound in anything other than a dry interior.
