Choose stability. Choose AinsworthEngineered.

steadi-tred-edge-with-gloved-handsExperienced builders know how the feel of a well-built stair affects buyers—and therefore, the builder’s bottom line. For solid stair systems that take the abuse of the construction site and then last for years in daily use, you can have confidence in AinsworthEngineered® products.

Our SteadiTred® stair treads are designed expressly to withstand heavy traffic without chipping or cracking, and our 1-1/4″ Durastrand® 0.8E Rimboard makes sturdy stringers. Together with 7/16″ OSB for risers, they’re a complete stair solution for multi-family residential and commercial construction.

They’re weather resistant and rugged, so you won’t need temporary stairs—they won’t break down even under jobsite conditions. Like all Ainsworth products, they have the engineered wood advantage: they’re consistent in dimension and density, so your crews won’t waste time picking through lumber, and you won’t have any waste or call-backs for warped, cupped or squeaking stairs.

AinsworthEngineered wood products are manufactured in a number of North American mills, with wood sourced from sustainably managed North American forestlands.
