B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Grip Strut, 14 ga

Each plank of the Eaton B-Line Grip Strut four diamond series runs 120 inches long by 9.5 inches wide, with a 2 inch channel depth. For a walkway wider than 9.5 inches you lay multiple planks side by side across your supports; the 2 inch channel is the leg height that sits on the framing, so allow for it when setting your finished walking surface elevation.

Yes. The four diamond Grip Strut plank is listed as OSHA compliant, and the serrated diamond openings are what earn it that: they give non-slip footing in all directions, which is the point on a mechanical platform, catwalk or rooftop access run where oil, water or ice is in play.

Mill-galvanized steel is the standard finish here, which suits dry interior and normally sheltered exterior use such as mechanical rooms, equipment platforms and covered catwalks. Mill-galvanized means the zinc coating was applied to the coil before fabrication, so the sheared edges and punched openings are left bare steel and will show rust first. For constant wet, wash-down or corrosive duty, specify a hot dip galvanized or stainless plank instead.

The diamond count is the number of rows of serrated diamond openings across the width of the plank. Four diamond gives the 9.5 inch walking width here. Two and three diamond planks are the same product in narrower widths, used for single-channel treads and narrow access runs. Pick the diamond count by the walkway width you need, not by strength alone.
