Cast Stair Nosing

American Safety Tread cast metal stair nosings have been installed in thousands of projects throughout the United States. Virgin grain granules cast into the walking surface while the metal is in a molten state create ab anti-slip tread that lasts the life of the stairway.

LONGEST WEARING: Stair nosings shown here ensure anti-slip protection for pedestrians. They also prevent wear and deterioration at the front edge of each step, greatly extending the life of the stairway.

IMPACT RESISTANT: Cast nosings are manufactured with alloys that create highly impact-resistant treads to withstand heavy traffic on interior and exterior stairways.

BARRIER FREE: These stair nosings are in full compliance with the Barrier-Free Code for all stairways. They offer a solid anti-slip surface and a gently radiused front edge with no projection beyond the riser.

ANTI-SLIP SURFACE: Maximum protection against slipping accidents is established through the proper blend of abrasive granules permanently embedded in the exposed walking surface. The process provides traction underfoot even when wet and oily.

ECONOMICAL: Our advanced manufacturing equipment and special American Safety Tread molding process assure the lowest cost per unit.
