B-Line Eaton series Grip Strut four diamond plank, 120" Grating length, 9.5" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .100" Thick

It's a 10 foot run: 120 inches long by 9.5 inches wide, with a 1.5 inch channel depth formed from 12 gauge aluminum. The 1.5 inch side channels are the structural legs, so the plank sits 1.5 inches above whatever framing you set it on. Plan your support spacing and openings around the 9.5 inch width if you're ganging planks side by side to cover a wider walkway.

The Grip Strut four diamond plank is listed as OSHA compliant and is intended for safe, sturdy footing where non-slip surfaces are required. The four diamond pattern gives a serrated, self-cleaning tread surface, which is why it gets specified for catwalks, mezzanine walkways, equipment platforms and stair treads in industrial and utility work.

This plank is aluminum, which is the usual pick for outdoor, wash-down, coastal or chemical-exposure areas where plain or galvanized steel would corrode, and for anywhere the crew has to carry and set planks by hand. Steel versions of the same four diamond profile carry more load per span, so if you're spanning long supports under heavy traffic or rolling loads, steel is the better choice. For elevated utility platforms, tank tops and rooftop access runs, the aluminum is what most spec writers land on.

Yes. The catalog weight on the 120 inch aluminum plank is 1.62 lb, so it's a one-man carry up a ladder or through a hatch. That handling advantage is the main practical reason crews choose aluminum over steel plank on retrofit platform work in occupied buildings.
