Wooden stair treads offer a classically beautiful look and warmth underfoot. Common woods for custom treads include Tiger Maple, Birch, Ash, Walnut, and Pine. For durability and slip-resistance in commercial applications, molded fiberglass and metal treads may be installed over a cement or wooden sub-structure. Grate-style treads in galvanized metal act as boot/shoe scrapers, removing mud and snow to help keep indoor floors clean.
