These wheels have polyolefin treads and cores. The wheels have a solid-cast, one-piece design that ensures the tread will not separate from the core. These lightweight, corrosion-resistant wheels can withstand impacts and exposure to water, oils, and chemicals. They are also nonabsorbent and can be steam cleaned. They will not mark or chip floor surfaces. Polyolefin tread wheels are not suitable for prolonged exposure to heat or cold. They are used on office furniture and display fixtures in institutional settings.

These wheels have plastic or phenolic treads and cores that resist corrosion. The wheels' tread and core are made from the same material. The wheels' hard treads provide smooth rolling and good maneuverability and are less damaging to floors than wheels with metal treads. Plastic and phenolic tread wheels are used on carts, racks, and similar equipment in a range of institutional and industrial applications.
