RWM Forged Steel wheels are hot forged from medium carbon steel providing maximum strength and durability. These wheels are virtually indestructible within their capacity range. These forged steel wheels should not be confused with ductile iron or heavy-duty cast iron wheels offering both lower cost and reduced capacities. Bore sizes can be altered and keyways can be installed on most sizes. Forged steel wheels can be used in the roughest, most demanding, abusive applications on the poorest floors under the heaviest of loads. Forged steel wheels are the only choice when extra heavy duty loads on poor floor conditions need to be moved safely.
