B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Steel, 5" Channel size, Galvanized, Grip Strut, 10 gauge

Each B-Line Grip Strut five diamond plank runs 120 inches long by 11.75 inches wide, with a 5 inch channel height. So a single plank gives you a 10 foot run of walking surface just under a foot wide. For wider platforms or catwalks, planks are laid side by side to build out the width you need.

The Grip Strut five diamond plank is listed as OSHA compliant, and the serrated five diamond surface is the reason: it is built to give safe, sturdy footing where non-slip is required. That is what makes it the usual choice for mezzanine walkways, catwalks, and equipment access platforms in industrial plants.

It is steel with a mill-galvanized finish, which is the standard corrosion protection for outdoor and washdown locations, damp pump rooms, and rooftop access runs. Mill-galvanized means the zinc is on the coil before forming, so cut ends and punched openings are bare steel; in a heavily corrosive or chemical environment you would want a stainless or aluminum grating instead.

A single 120 inch plank weighs 17.5 lb, so one worker can handle it up a ladder or across a scaffold without a lift. That low weight is also what keeps dead load down when you are adding walkway over an existing structure.

The 5 inch dimension is the depth of the formed channel, meaning the plank stands 5 inches tall from the support surface to the walking surface. Deeper channel means more span capacity, and the 5 inch is the heavier of the Grip Strut plank depths, used where supports are spread further apart. Set your support spacing from the load table for the span you need, and allow the 5 inches of height in your clearance and step-up dimensions.

10 gauge is the heaviest material thickness offered in Grip Strut plank and is what gets specified for regular foot traffic, tool carts, and maintenance access rather than occasional use. Paired with the 5 inch channel depth, it is the stiffest combination in the line.

The 55010 10 GL is the plank itself. Hold-down clips, saddle clips, or bolts to fasten the channel legs to your support steel are ordered separately, so count your support points and add fasteners to the order before the crew is on site.

Yes, the steel plank can be cut on site to fit your bay spacing, and that is normal practice with a 120 inch stock length. Because the finish is mill-galvanized, the cut end will be bare steel, so touch it up with a cold galvanizing compound if the run is outdoors or in a wet area.
