18″ Wood Stair Treads

18-inch Wood Treads & Landing Panels

Our 18-inch deep wood panels are solid wood blanks built for large staircase applications. At 18" deep and a standard 1" thick, they are primarily used for landings, platforms, and oversized winder treads. The extra depth gives builders plenty of material for custom cutting on turning or split-level stairs.

Each panel is graded clear on the top face for a clean finished surface. The underside may show natural wood characteristics that do not affect structural performance. All panels arrive sanded and unfinished, ready to be cut and finished on site.

We stock these large-format panels in a range of wood species and lengths so you can get the material you need without long custom millwork lead times. Select the species and length below.
