Abstract
An improved stair tread for use in both residential and commercial construction directly beneath carpet and padding material is disclosed. The improved stair tread is fabricated from an engineered wood product such as Oriented Strand Board made of wood strips in a four layer process. Each surface layer is oriented perpendicular to the core layers and bonded with phenolic resin or other similar binding agents under intense heat and pressure to achieve the strength and performance criteria required for stair treads. The improved stair tread is machined from one inch thick structural panels using standard woodworking tools and has excellent workability. The finished stair tread is provided with a rounded, forward edge and a riser groove extending along its entire length. The improved stair tread provides a cost effective alternative to traditional solid wood stair treads.
