Urethane on Iron wheel is liquid cast and chemically bonded to machined, cast-iron cores. Capacities rival those of steel wheels. Careful attention is made during the bonding process to assure that each wheel meets high performance standards. UI wheels are non-marking, and resistant to abrasion, chemicals, and oil. These wheels will typically outlast rubber wheels. Temperature range: -40 degrees F to 180 degrees F.
