B-Line Eaton series Grip Strut stair tread, 360" Grating length, 9.5" Grating width, Steel, 1.5" Channel size, Plain, Stair tread, 14 gauge

The Grip Strut tread measures 360 inches of grating length by 9.5 inches of grating width, with a 1.5 inch channel size and 1.5 inch product height. The 9.5 inch width is the walking depth of the step; the 360 inch length is the material run, so it is cut to the stair width you need rather than supplied as a single fixed-width step.

Yes, the B-Line Grip Strut stair tread is listed as OSHA compliant, and the whole point of the diamond-pierced Grip Strut surface is slip resistance where sure footing is required. That covers plant stairs, mezzanine access, and equipment platforms.

This one is plain steel with no coating, so it is bare carbon steel. For outdoor stairs, wash-down areas, or anywhere with salt or moisture, specify a galvanized Grip Strut instead, or paint the plain tread after cutting. Plain is for dry interior use or where you are applying your own finish system.

Grip Strut is a single formed steel sheet, here 14 gauge, with the tread surface pierced and formed into raised diamond openings that shed water, mud, and debris and grip from every direction. Bar grating relies on serrated bar edges and is heavier for the same span. Grip Strut's channel form, 1.5 inches deep on this tread, gives it the stiffness across a stair run without the weight; at 3.6 lb it handles far easier on a retrofit.

Product weight is listed at 3.6 lb, and the material is 14 gauge steel. That is light enough for one person to carry and set in place, which is a practical difference from a welded bar grating tread of the same footprint.
