B-Line Eaton series Grip Strut stair tread, 288" Grating length, 11.75" Grating width, Aluminum, 2" Channel size, Stair tread, .080" Thick

It's listed as OSHA Compliant. The Grip Strut surface is a perforated, serrated plank made for non-slip footing on stairs and walking surfaces, which is what OSHA looks for on industrial stair treads. Confirm your riser and stringer layout separately, but the tread itself carries the compliance.

The plank is 288 inches long, which is 24 feet, so a single piece covers a very wide stair or can be cut down to multiple treads of your stair width. Walking width is 11.75 inches, deep enough for a standard commercial tread run.

Two inch channel size, and the overall height of the section is 2 inches. That 2 inch formed channel is what gives the plank its stiffness over a span and what your carrier angles or stringer brackets bolt against, so plan your end connections and riser height around a 2 inch deep section.

Aluminum is the material here, which is why it is the common pick for exterior platforms, wash-down areas, rooftop equipment access and coastal sites where a painted carbon steel plank would rust at every cut edge. It's also light: 6.2 lb for the section. Where you need maximum load capacity or abrasion resistance from heavy traffic and cart wheels, a galvanized steel Grip Strut plank is the tougher option.

6.2 lb for the section. Aluminum at .080 inch thickness keeps it light enough for one or two people to carry and set a full length piece without a lift, which is the practical reason crews specify aluminum over steel on elevated platform work.

14 gauge, formed from .080 inch aluminum. That's the sheet thickness you're spanning with, so it governs how far apart your supports can sit under the plank.
