Weyerhaeuser SturdiStep® Stair Treads


SturdiStep® stair treads are engineered to get the most from natural wood. Each piece is precisely engineered for this end use and is uniform in size, which helps reduce jobsite waste.

Uniformity from piece to piece—and within each piece—means the customer can buy with confidence. SturdiStep stair treads are also warranted against delamination, cupping and warping.

Our resins can withstand the demands of normal construction delays so SturdiStep treads can be installed during the framing stage, saving on labor and other costs associated with temporary stair treads.


Step up your game with precision, convenience and lower costs.

SturdiStep stair treads are manufactured to be flat, straight, and a precise thickness. Knot-free and uniform throughout, they are the only wood stair treads warranted against delamination, cupping and warping.

Combine SturdiStep treads with Trus Joist® TimberStrand® LSL stair stringers for a solid, stable stair system — and fewer customer callbacks. They're also durable enough to withstand normal construction delays so builders save on the labor and material costs associated with temporary stair treads.
