B-Line Eaton series Grip Strut five diamond plank, 144" Grating length, 11.75" Grating width, Steel, 3" Channel size, Mill-galvanized, Grip Strut, 12

Each Grip Strut plank runs 144 inches long and 11.75 inches wide, with a 3 inch channel depth. So one piece covers a 12 foot run about a foot wide. For wider walkways or platforms, planks are set side by side until you reach the width you need.

The Grip Strut five diamond plank is listed as OSHA compliant and is made for safe, sturdy footing where non-slip is required. That is what puts it on catwalks, mezzanine walkways, stair treads and equipment platforms in industrial and institutional facilities.

The plank is steel with a mill-galvanized finish, which is a zinc coating applied to the sheet before forming. That handles normal industrial interiors and sheltered exterior use. Cut ends and punched openings are raw steel after fabrication, so in wet or washdown areas expect edge rusting unless the cuts are touched up with a cold galvanizing compound.

12 gauge is the sheet thickness the plank is formed from, and it is the heaviest of the common Grip Strut gauges. Paired with the 3 inch channel depth, that is the combination specified for longer unsupported spans and heavier foot and cart traffic. Lighter gauges of the same profile are meant for shorter spans between supports.

Grip Strut is a one piece formed steel plank with punched diamond openings that turn up into serrated grip surfaces, so traction comes from the surface itself rather than from serrated bar edges. It is lighter to handle and the openings drain and shed debris. Bar grating carries higher concentrated loads and is the usual choice for vehicle or heavy equipment areas. For personnel walkways, stairs and equipment access where slip resistance is the driver, the 3 inch channel plank is the normal specification.

It is listed at 7 lb, so weight is not the issue, the length is. A 12 foot, 11.75 inch wide plank is awkward for one person to carry up a ladder or maneuver in a chase even at that weight. Two hands on a scaffold, or a second person on a platform install.

Order it as Eaton B-Line part 53012 12 GL. That number carries the five diamond plank profile, 3 inch channel, 12 gauge steel and mill-galvanized finish in one call out.

Yes, the planks are field cut to suit the run. It is 12 gauge steel, so a metal cut off saw or band saw with an abrasive or metal blade handles it. Since the mill-galvanized coating is on the sheet before forming, the fresh cut edge is bare steel and should be treated if the location sees moisture.
