Tread CA A contemporary adaptation of a Victorian stair, this cast design fits elagantly in traditional as well as modern settings. Each tread is a one piece casting in aluminum, precision machined to an exact riser height. Platforms are designed to fit square and round openings. The tread surface is a square diamond pattern.
Finishes Steel stairs are normally finished with a shop coat of modified alkyd resin rust-inhibiting primer, which is gray in color. Additional finishes include hot dip galvanizing or Awlgrip®, a polyurethane paint which is available in a wide range of colors and can be supplied on a custom basis. Aluminum stairs receive an etching wash primer. Hardwood tread overlays and railings are sanded to a 120 grit smoothness and finished with one coat of polyurethane sealer. At the customer's request, hardwood may be left unsealed for staining by others.
