This stair assembly features steel subtreads and type J risers filled with concrete, providing a durable stair tread configuration. The steel subtreads rest on locator angles that are factory-attached to the stringers. The design maintains an eleven-inch nose-to-nose dimension and a maximum seven-inch riser height, with the riser height varying as needed for the run.
