We can fabricate different styles of stair treads in a variety of materials, styles, and sizes. We are happy to assist you with your selection and further details on the treads. Cutouts, notching, banding, and toe plates are available. Type A stair treads are offered in an aluminum swaged construction and are made with a corrugated (grooved) nosing that is welded to the leading edge of the tread. The stair treads are fabricated from stock panels.
