A two-by-twelve-inch tube steel stringer frames into the concrete slab and supports a welded steel pan and riser stair system. The steel pan system features two inches of concrete infill at the treads with a scheduled finish and a two-inch contrast strip at the nosing. A one-by-one-inch angle clip connects each stringer to the stair assembly with welds at seams and clips. A painted steel bent plate is shaped to match the pan riser at the landing transition.
