B-Line Eaton series Grip Strut five diamond plank, 120" Grating length, 11.75" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .100" Thick

The Grip Strut five diamond plank is listed as OSHA compliant, and the serrated diamond openings are made for safe, sturdy footing where non-slip surfacing is required. That is the usual reason it gets specified for catwalks, mezzanine walkways, platforms and stair treads over smooth plate.

This plank is aluminum, 12 gauge, which is the version people pick when the walkway is outdoors, near coastal air, or in a wet or chemical area where painted steel would rust and galvanizing adds cost. It is also the lighter option to carry up a ladder or onto a roof. Where the deck takes heavy rolling loads or impact, a steel plank is the tougher choice.

The plank itself is the walking surface only. You supply the supporting steel or channel underneath and the fasteners or hold-down clips that attach it. Plan your support spacing so the 1.5 inch channel legs land on framing members, and remember each plank is 120 inches long, so intermediate supports are normally needed across that span rather than end bearing alone.

Yes. Aluminum plank at 12 gauge cuts cleanly with a circular saw and a metal cutting blade, so a 120 inch piece can be trimmed to length on site for a shorter platform bay. Cut ends should be deburred, and the cut should still land on a support so the channel legs bear.
