The University solid cast iron stair tread is a traditional design with a full 1″ diameter full round bullnose, turndown ogee lip and diamond pattern relief stepping surface. The 3/4″ thick solid cast iron tread is structural and self supporting across its width when bolted on the ends to structural stringers. The University tread was designed for assembly with our lighted cast iron risers or as a stand alone tread for open risers or risers by others.

Features:

– Structural and fully self supporting over tread width. Engineered and rated for deflection of less than L/360 over the stair width when properly attached at stringers with approved fasteners. No support by the riser or other spanning steel required.

– 11″ tread depth measured nose to nose of adjacent tread in typical installation.

– 1″ nosing projection from face of riser for comfortable stair climbing.

– Integrally cast diamond traction relief pattern and nosing fluting for a traditional appearance and secure traction surface.

– 7/8″ tall ogee nosing turndown allows a range of stair rise from 6 1/2″ to 7″ with standard 5 5/8″ riser casting. The nosing turn down hides the riser height allowance to make installation flexible for a range of step rises. Tread installation does not require a riser for support.

– Includes 7/16″ drilled and countersunk holes for 3/8″ fasteners. Fasteners not included.

– Finished with durable rust converted black iron patina for easy to maintain “no paint” finish. Black iron patina finish maximizes the inherent no-slip properties of sand cast iron with diamond relief pattern. Optionally furnished as bare metal casting ready for paint coating by others.

Manufacturing and Availability:

The University tread is cast in our foundry from 100% recycled scrap iron and steel and standard widths are available as made to order and shipping from the foundry typically within 10 weeks. The rust converted patina typically requires a minimum of 6 weeks time for proper rust bonding and bare metal treads can be shipped in 4 to 6 weeks. The most common widths may be stocked for quick shipment.

Standard widths are any 2″ increment from 36″ to 54″.  The most common widths are 36″ and 48″.
