B-Line Eaton series Grip Strut three diamond plank, 120" Grating length, 7" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .100" Thick

The Grip Strut three diamond plank runs 120 inches long and 7 inches wide, with a 1.5 inch channel depth. That 7 inch width is the walking surface, so for a wider catwalk or platform you run planks side by side across the span rather than looking for a wider single piece. Support spacing has to suit the 1.5 inch channel size and the 12 gauge aluminum.

Yes. The Eaton B-Line Grip Strut plank is listed as OSHA compliant, and the three diamond pattern is the non-slip surface type used where safe, sturdy footing is required, such as platforms, catwalks and access walkways.

This plank is aluminum rather than steel, which is the material spec people choose for wet, humid, or corrosive exposure because it will not rust the way plain carbon steel does. It is 12 gauge with a 1.5 inch channel for stiffness. For structural spans where you need higher load capacity than aluminum gives, a steel or galvanized version of the same three diamond plank is the usual swap.

The diamond count describes how many rows of the pierced non-slip diamond pattern run across the width of the plank. Three diamond gives the 7 inch walking width here, on a 1.5 inch channel. Two diamond is the narrower profile used for stair treads and tight access runs, and four or five diamond planks are wider for full platform decking. Pick the diamond count by the width of walkway you need to cover.

The 31510 10 AL is the plank only. Hold-down clips, saddle clips, bolts or welding are specified separately based on how you are attaching to the supporting steel or aluminum framing, so add that hardware to the order.

Yes. Aluminum construction keeps the weight low, listed at 1.34 lb, so a single installer can handle and place a 120 inch plank without a lift. That is a big part of why crews pick aluminum over steel for elevated platform and mezzanine walkway work.

The plank ships at 120 inches, and field cutting aluminum grating to length is common practice with a saw and the right blade. The 1.5 inch channel legs are what carry the span, so keep your cut ends landing on support framing.
