About this detail

This stair assembly features a steel pan and riser stair system with two inches of concrete infill at the tread pans. The pan rests on an L2 inch by 2 inch steel angle and is welded at seams and to angle clips at each stringer. The support structure consists of an HSS12x2x1/4 steel tube painted where exposed, unless noted otherwise. A 1 1/2 inch outer diameter steel pipe vertical is continuously welded to the stringer, ground smooth, and painted to a scheduled finish with a 2 inch contrast strip at the nosing.
