B-Line Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Aluminum, 3" Channel size, Grip Strut, .080" Thick

Yes, the four diamond Grip Strut plank is listed OSHA compliant, and the serrated diamond surface is intended for safe, sturdy footing where non-slip is required. That covers the usual mechanical mezzanine, rooftop crossover and equipment access walkway in an industrial or institutional facility.

Model 43012 12 AL is the aluminum version, and aluminum is the one to pick for exterior rooftop, coastal or wash-down areas where a painted steel plank would need coating maintenance. It is also the lighter option to carry up a ladder for a single-installer job. Steel or galvanized Grip Strut is the alternative where you need higher load capacity over longer unsupported spans.

It is formed from 14 gauge aluminum, .080 inch thick, with a 3 inch deep channel on each side. The channel depth is what gives the plank its stiffness between supports, so keep those edges down and bearing on your structural members when you set it.

The 43012 12 AL is the plank only. Hold-down clips, bolts or self-drilling fasteners to secure it to your beams or angle supports are ordered separately, so add them to the same order if the walkway is going up in one trip.

The four diamond pattern is a punched and serrated open surface, so water, oil and light debris fall through rather than pooling. That open grating is the reason it is specified for non-slip footing in wet or oily plant areas. It is not a solid plate, so anything you set on it should be sized larger than the diamond openings.
