Carrier angles are a stairpan and stair tread support used in the construction of steel staircases. Carrier angles are welded or bolted to the inside of a steel Cee stringer channel and the underside of stairpans or treads. Carrier angles provide a strong and secure connection point for pans and treads to stringers. Our carrier angles are formed out of prime sheet steel. Our standard carrier angles have minimal field adjustability allowing fabricators to adjust them to achieve a desired pitch.
