Metal pan riser and sub-tread units receive a two-inch concrete fill reinforced with welded wire fabric. The metal pan assembly rests on steel brackets welded or secured to the structural steel stringer. A steel clip angle provides additional structural support at the stringer base. Typical stair nosing is installed at each riser unless noted otherwise, and a sanitary cove is detailed at the floor intersection.
