B-Line Eaton series Grip Strut stair tread, 360" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Stair tread, 12 gauge st

The Grip Strut tread T42012 30 GL measures 360 inches of grating length by 9.5 inches of grating width, with a 2 inch channel height. At 360 inches (30 feet) it is a stock length meant to be cut to your stair width rather than dropped in as a single finished step, so plan on field cutting to the riser spacing and tread run you need.

Yes. The Grip Strut tread is listed as OSHA compliant, and the diamond-perforated surface is intended for safe, sturdy footing where non-slip is required, which is what plant catwalks, mezzanine stairs and equipment platforms are inspected for.

The finish on this tread is mill-galvanized steel, which is zinc coating applied to the coil before forming. That covers the flat faces but leaves cut ends and sheared perforations bare, so it suits covered industrial interiors and sheltered exterior stairs better than constant wetting or chemical washdown. If you cut it to length, touch up the cut ends with a zinc-rich coating.

It is formed from 12 gauge steel with a 2 inch deep channel on each edge. The 2 inch channel is the structural element here, not the sheet thickness on its own, and it is the heavier of the common Grip Strut channel depths. Span between stringers is what governs load, so set your stringer spacing from the stair design, not from the tread alone.

Order it as Eaton B-Line model T42012 30 GL. That designation covers the 9.5 inch wide, 12 gauge, mill-galvanized tread with the 2 inch channel in the 360 inch length.

No fasteners, end closure plates or nosings are included with the T42012 30 GL tread. It ships as the formed grating section only, so order your bolts, clips or weld-down attachment and any end plates separately to suit the stringer you are fixing to.

Grip Strut is a one-piece formed steel plank with a serrated, perforated walking surface, so it drains and sheds debris and gives traction in oil or ice without a separate abrasive nosing. Bar grating carries heavier concentrated loads over longer spans but is heavier to handle and needs banding and nosing work at every cut. For stairs and access platforms where footing is the concern, the 2 inch channel Grip Strut tread is the simpler install.

The catalogued weight is 5.4 lb. It is light enough for one person to carry and cut, which is part of why Grip Strut gets used for retrofit stairs and platform walkways where you are working above grade with hand tools.
