Technical Specification

Step treads shall be manufactured to OEM color and dimensional specifications using abrasion resistant vinyl compounds embossed with a widely spaced raised pebble pattern. Nominal pebble dimensions shall be: 0.350" diameter at the base and 0.250" diameter at the top and 0.125" in height. Nominal pebble spacing shall be 0.680" center to center. The pebble pattern shall be in rows, with each row offset 0.340" from the preceding row. The pebble pattern shall be consistent across the surface of the nosing and tread. There shall be no gaps in the pebble pattern. Step Treads shall have an integral, bright white nosing with less than 1/4" total width variation across the tread face. Tread and nosing shall be fused forming a seamless joint and shall be permanently bonded to non-metallic Koroseal polymer step backing. The assembled step tread shall exhibit no significant deterioration after a 500-hour salt spray test.
