ABSTRACT:
A metal stairway constructed on site in a metal framed house. The stair steps are supported between a pair of trimmed sheet metal stringer panels on each side of the stairway. Each step of the stairway is formed of metal treads and risers cut to appropriate lengths from conventional joist members provided on site for the metal framed house. The metal treads and risers are attached at opposite ends thereof to the respective stringer panels by way of standard angled brackets provided on site for securing metal framing members together. Threaded self-drilling fasteners attach each angled bracket to a corresponding stringer panel and to an associated metal tread or metal riser. Wooden treads and risers are attached over the metal treads and risers by standard self-drilling screws.
