B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Steel, 2.5" Channel size, Mill-galvanized, Grip Strut, 12

The Grip Strut four diamond plank, model 42512 10 GL, runs 120 inches long by 9.5 inches wide with a 2.5 inch channel depth. That 10 foot length and 9.5 inch walking width is what you plan your supports around; for a wider walkway you run planks side by side to build up the width you need.

Yes. The four diamond Grip Strut plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required, which is what it is specified for on catwalks, platforms, and equipment access walkways.

Mill-galvanized steel is the standard finish on this 12 gauge plank and it suits general industrial use, including covered outdoor and utility locations. For constant wet, corrosive, or chemical wash-down service, a hot-dip galvanized-after-fabrication or stainless plank is the better call, since mill-galvanized leaves the sheared edges of the diamond openings bare.

Four diamond refers to the number of rows of pierced, raised diamond openings across the 9.5 inch width of the walking surface. More diamond rows means more walking width per plank; a two or three diamond plank is narrower and used for stair treads and tight runs, while this four diamond piece covers wider walkway sections in a single member.

Yes. The plank is roll formed with 2.5 inch deep channel legs down each side, which is also the overall product height. Those legs give the plank its stiffness and are what you clamp, bolt, or weld down to the supporting steel, so no separate frame is needed under a single plank run.

12 gauge steel is the common industrial weight for grip strut planking and is what gets used for maintenance platforms, mezzanine walkways, and equipment access with regular foot traffic. Load capacity depends on how far you span between supports, so set your support spacing from the load you expect rather than from the gauge alone.

What you order here is the plank itself, model 42512 10 GL, at 120 by 9.5 inches. Hold-down clips, saddle clips, or bolts for securing the 2.5 inch channel legs to your supporting steel are ordered separately, so add them to the same order if the walkway is going up in one trip.

It weighs 5.7 lb, so a single 120 inch plank is a one-man carry and lift up a ladder or into a rack. That low weight is why grip strut planking gets used for retrofit walkways over existing structure rather than heavier bar grating.

The 120 inch plank is field cuttable with a metal chop saw or band saw to suit the opening. Cutting exposes bare steel at the ends because the mill-galvanized coating is applied to the coil before forming, so touch the cut ends up with a cold galvanizing compound if the walkway sees moisture.
