Concrete fill with welded wire fabric reinforcing is placed over a metal pan riser and subtread. A stair nosing is typical at each riser unless noted otherwise, with a sanitary cove provided at the base. The metal pan assembly bears on steel brackets and connects to a structural steel stringer via a steel clip angle. Dimensions indicate tread depth and typical riser height.
