We renovated the main stairway in our school with these aluminum treads and they look fantastic. Professional appearance, aggressive traction, and the pre-drilled holes made installation easy. Our maintenance team says they’re the best stair treads we’ve ever installed. Zero complaints from staff or parents about slippery stairs since the upgrade.

Product Overview
The 9x36 inch Aluminum Stair Tread from Sure-Foot Industries features a heavy-duty double-cavity design that provides superior anti-slip protection on industrial and commercial staircases. Measuring 9 inches deep by 36 inches long with a 1.250-inch nosing overhang, this tread is engineered to fit standard-width stairs with a 9-inch step depth. The mineral abrasive epoxy surface is chip and crack resistant, delivering long-lasting slip resistance in high-traffic environments. Each tread comes pre-drilled with counter-sunk holes for straightforward installation and weighs approximately 7 lbs.

Expert Insights
The 9-inch depth is designed for standard stair treads and works best on stairs with a tread depth of approximately 9 inches, while the 36-inch length fits most standard residential and light commercial stairways. For wider staircases, consider the 48-inch version of this same tread for full edge-to-edge coverage. The double-cavity design holds twice the anti-slip abrasive material compared to single-cavity treads, making it ideal for wet or oily industrial environments. Fasteners are not included, so plan to use appropriate stainless steel or galvanized screws matched to your stair substrate material.
Anti-Slip Stair Treads & Tape in Action
Commercial buildings, schools, hospitals, and government facilities install aluminum stair treads during renovation and new construction. The extruded aluminum withstands decades of heavy foot traffic without deformation — and the grit-epoxy surface maintains traction through years of wear, cleaning, and weather exposure.
Purchased by facility managers, safety directors, maintenance supervisors, property managers, general contractors, and procurement teams. All products are manufactured by Sure-Foot Industries in the USA and backed by AbsorbentsOnline’s 40+ years of safety equipment expertise.

What Our Customers Say
Real reviews from the facilities, field crews, and agencies that count on us.
-
-
These aluminum treads survived three harsh New England winters without any visible degradation. Salt, ice melt, heavy snow boots, and constant foot traffic — they look just as good as the day we installed them. The grit surface still bites hard. These are a once-and-done installation, no annual replacement.
-
