Concrete-filled metal pan treads are supported by a fourteen-gauge typical J-riser and metal support angles that connect to the steel stringer. The stair assembly ties into a composite metal deck with concrete topping at the floor level. Steel support angles connect the stair framing back to the structural steel girder, with structural connections coordinated per structural drawings.
