B-Line Eaton series Grip Strut stair tread, 288" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Stair tread, 12 gauge

The Grip Strut stair tread measures 9.5 inches wide by 288 inches of grating length, with a 2 inch channel size and 2 inch height. At 288 inches it is a single 24 foot length, so it is normally cut down on site to the individual tread runs you need rather than installed as one piece.

Yes. The T42012N 24 GL Grip Strut tread is listed as OSHA compliant, and the serrated grip surface is intended for safe, sturdy footing where non-slip is required. That is the reason it gets specified on plant stairs, mezzanine access and equipment platforms.

The tread is 9.5 inches wide, so it gives roughly a 9.5 inch run per step when installed as a single tread. If your stair design calls for a deeper run, two channels are set side by side rather than looking for a wider single piece in this size. Check the run dimension on the stair drawing against 9.5 inches before cutting the 24 foot length.

The tread is steel with a mill-galvanized finish, which gives corrosion resistance for sheltered outdoor and general industrial use. Mill galvanizing coats the coil before forming, so cut ends and punched openings are raw steel and should be touched up with a zinc-rich paint after you cut the 288 inch length to size. For constant wet, chemical or coastal exposure, a hot-dip galvanized or stainless tread is the better call.

12 gauge is the heaviest of the common Grip Strut sheet thicknesses and is what gets used for stair treads and walkway platforms carrying regular personnel traffic, rather than the lighter gauges used for light-duty covers. Combined with the 2 inch channel depth, the formed channel does the load carrying, so the deeper channel spans farther between stringers than a flat plank of the same gauge.

What ships is the Grip Strut tread section itself, model T42012N 24 GL, 9.5 inches wide by 288 inches long in 12 gauge mill-galvanized steel. Nosing, end plates and the bolts or clips that fasten the tread to your stringers are separate items, so order those with the job if the stair does not already have them.

Grip Strut is a formed, one-piece serrated channel with no welded intersections, and the diamond openings drain and shed debris, which is why it is chosen where footing in oil, water or ice matters most. Bar grating is stiffer for long clear spans and heavy rolling loads. Expanded metal is cheaper but has a flatter, less aggressive walking surface. For personnel stairs needing a non-slip surface, the 12 gauge Grip Strut channel is the usual specification.

Listed weight on the T42012N 24 GL is 5.4 lb. It is a light piece of steel to lift, but at 288 inches long it is awkward for one person to carry or hoist up a stair tower without flexing it, so plan on two hands at each end or cut it to tread length first.
