B-Line Eaton series Grip Strut three diamond plank, 120" Grating length, 7" Grating width, Steel, 1.5" Channel size, Galvanized, Grip Strut, 14 gauge

Each plank of the Eaton B-Line Grip Strut three diamond plank runs 120 inches long by 7 inches wide, with a 1.5 inch channel depth. So one piece covers a 10 foot run at a 7 inch tread width. For a wider walking surface you lay planks side by side, since the width is fixed at 7 inches per plank.

Yes. The B-Line Grip Strut three diamond plank is listed as OSHA compliant, and it is made for safe, sturdy footing where non-slip is required, which is what puts it on catwalks, mezzanine walkways, stair treads and equipment platforms. The diamond openings are punched and pressed so the edges themselves do the gripping, in all directions rather than one.

The finish here is mill-galvanized steel, which is the standard choice for covered outdoor and general industrial interiors. Mill-galvanized means the zinc was applied to the coil before forming, so the cut ends and the punched diamonds are bare steel and will show surface rust in a wet, salty or chemical washdown environment. For constant wetting or corrosive exposure, specify a hot-dip galvanized-after-fabrication or stainless plank instead.

This plank is formed from 14 gauge steel, the heavier of the common Grip Strut thicknesses. 14 gauge is what you use for walkways and platforms carrying regular foot traffic with support spacing at the wider end; lighter 16 or 18 gauge planks are for shorter spans and light-duty access. Channel depth is 1.5 inches, which is the structural leg doing the spanning.

Grip Strut is the pick when slip resistance is the driving concern, since the punched diamonds present gripping edges in every direction and shed oil, water and debris through the openings. Bar grating gives you more load capacity over long spans but a smoother bearing bar to walk on. Expanded metal is cheaper and lighter but does not grip the same way. This plank is specifically for safe, sturdy footing where non-slip is required, and it is OSHA compliant.

Yes, these handle easily by hand. The plank is light-gauge formed steel at 7 inches wide, so a single 120 inch piece is a one or two man lift depending on how awkward the access is. Its 1.5 inch channel height is shallow enough to pass through most framing openings during a retrofit.
