SturdiStep® Stair Treads

Engineered to get the most from natural wood

Each SturdiStep® stair tread is precisely engineered for its end use and is uniform in size, which helps reduce jobsite waste.

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

Our resins 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 of precise thickness. Knot-free and uniform throughout, they’re the only wood stair tread 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. Both these products are durable enough to withstand normal construction delays so builders save on the labor and material costs associated with temporary stair treads.
