Polyurethane on Steel wheels offer a longer wearing, higher capacity material than rubber, yet will not damage or mark floors like cast iron or steel. Polyurethane wheels possess a durability unmatched by any rubber tread wheel and are built to withstand permanent flat spots in the tread. The polyurethane resists most chemicals and oils and rejects floor debris.
Some polyu-on-steel are considered extreme duty. This combination of high-load urethane chemically fused to a steel core makes this wheel one of the most long lasting, rugged wheels available. It resists heat build-up and is excellent for applications where heavy loads and continuous usage cause regular poly wheels to degrade.
It provides floor protection, is non-marking and delivers a quieter ride than a hard tread or steel wheel.
