Mounting Dimensions
The most economical stair treads we offer.
Stair treads with projections provide good slip resistance that's more comfortable than serrated.
Serrated stair treads provide maximum slip resistance.
Powder-coated steel treads are for use in dry, noncorrosive areas.
Galvanized steel treads are more corrosion resistant than powder-coated steel.
