B-Line Eaton series Grip Strut stair tread, 432" Grating length, 11.75" Grating width, Steel, 2" Channel size, Stainless steel type 304, Stair tread,

The Grip Strut tread measures 11.75 inches across the grating width with a 2 inch channel size, so it gives just under a foot of walking depth per step. The 2 inch channel height is what sits between the tread surface and the stringer or carrier angle, so account for that when you set your riser spacing.

Yes. The Eaton B-Line Grip Strut tread is listed as OSHA compliant, and the pierced, serrated surface is intended for safe, sturdy footing where non-slip walking surfaces are required. That makes it the usual choice for plant catwalks, mezzanine stairs, and equipment access platforms.

This tread is type 304 stainless steel, which is the grade specified for food processing, washdown areas, water treatment, and outdoor coastal exposure where galvanized steel would eventually rust at the cut edges. If your facility is handling chlorides or heavy salt brine, 316 is the grade normally specified instead of 304.

16 gauge steel. On Grip Strut, the strength comes from the formed channel profile rather than sheet thickness alone, so the 16 gauge material with the 2 inch channel depth is the standard light-to-medium duty industrial tread build. For heavier rolling loads or longer unsupported spans, a deeper channel tread is the direction to go.

No fasteners are included with the tread itself. Grip Strut stair treads have pre-punched end plates that bolt through the stair stringer, so you will need to order carriage bolts, nuts and washers separately, and in stainless to match the type 304 tread if corrosion is the reason you chose stainless in the first place.

Order it as Eaton B-Line model T52016 36 SS. The SS suffix is the type 304 stainless version, which matters if you are matching existing treads on a stair run, since the galvanized and stainless versions of the same profile look similar once installed but will not weather the same way.

About 3.7 lb per tread, so a single installer can hand-carry and set several at a time. That light weight is typical of pierced plank grating and is one reason it gets used for retrofit stair work in occupied buildings where hauling bar grating is impractical.

The profile is the same serrated, pierced plank used for walkways and platforms, and it is made for any location where non-slip footing is required. The difference is the tread version comes with formed end plates sized for stringer attachment on a stair. For a flat mezzanine or catwalk deck, plank grating in continuous lengths is the cleaner buy because you are not paying for end plates you do not use.
