Metal Wheels

Choose metal wheels when your per-wheel load exceeds what polymer materials can safely handle, typically above 3,000 to 5,000 lbs per wheel. Also choose metal when operating temperatures exceed the limits of polymer materials, or when the wheel must resist physical damage from impacts, debris, or metal chips on the floor.

Yes, metal wheels can crack, chip, and wear concrete, tile, and coated floor surfaces, especially under heavy loads. They are intended for industrial environments where floor cosmetics are not a priority. If you need high load capacity with floor protection, consider polyurethane-on-iron core wheels.

Bare steel and cast iron wheels can rust when exposed to moisture. Regular inspection and lubrication of bearings are recommended. Some metal wheels are available with protective coatings or plating to reduce corrosion. In clean, dry indoor environments, maintenance requirements are minimal beyond bearing lubrication.

Steel wheels can typically operate at temperatures up to 800 degrees Fahrenheit or higher depending on the heat treatment and bearing type. Cast iron wheels handle similar temperature ranges. The practical temperature limit is often determined by the bearing and lubricant rather than the wheel itself.

Metal wheels share a common set of advantages: exceptional compressive strength, resistance to flat-spotting under sustained heavy loads, dimensional stability at elevated temperatures, and indefinite shelf life with no degradation over time. They are the standard in foundries, steel mills, heavy manufacturing, die handling, mold transport, and any operation where the loads are simply too heavy for any other material.

The trade-offs with metal wheels are well understood. They provide no shock absorption, produce significant noise on hard floors, can damage concrete and tile surfaces, and will rust without proper maintenance or protective finishes. Metal wheels should not be used on finished, coated, or soft floor surfaces unless floor protection is not a concern. Within this category, steel and cast iron each offer distinct properties.
