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 9x48 inch Aluminum Stair Tread from Sure-Foot Industries delivers heavy-duty anti-slip protection with its double-cavity design, engineered for wider commercial and industrial staircases. At 9 inches deep by 48 inches long with a 1.250-inch nosing overhang, this tread covers wider stairways that the standard 36-inch model cannot fully protect. The mineral abrasive epoxy surface is chip and crack resistant, ensuring reliable traction even in demanding high-traffic or wet conditions. Each unit is pre-drilled with counter-sunk holes for efficient installation and weighs approximately 9 lbs.

Expert Insights
The 48-inch length is specifically sized for wider industrial and commercial staircases where 36-inch treads would leave exposed edges, creating a tripping hazard. Choose this 9-inch depth model when your stair tread measures approximately 9 inches from the front edge to the riser. The double-cavity channels hold significantly more anti-slip abrasive material than single-cavity designs, providing enhanced traction in environments exposed to water, oil, or chemical spills. Always measure your stair width before ordering and select screws rated for your stair substrate, whether concrete, steel, or wood.
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.
-
