Polyurethane tread on plastic core wheels weigh less and provide more corrosion resistance than wheels with a polyurethane tread and metal core. They also can withstand exposure to water. These wheels are used on shopping carts, platform trucks, and similar equipment in a range of commercial and industrial applications.

Polyurethane tread on iron core wheels are used on industrial equipment. Wheels with iron cores provide good wear resistance and typically have higher load capacities than wheels with aluminum or plastic cores. Iron will rust if it gets wet, so these wheels are best suited for dry environments.

These wheels each have a polyurethane tread that's been chemically bonded onto a steel core. Wheels with steel cores provide more wear resistance and have higher load capacities than wheels with iron, aluminum, or plastic cores. Polyurethane tread on steel core wheels are used for low-speed towline applications in indoor and outdoor industrial settings. Steel will rust if it gets wet, so these wheels are best suited for dry environments.

These wheels have been impregnated with an antimicrobial compound that prevents damaging, odor-causing microbes from growing on the wheels. Polyurethane tread on plastic core wheels weigh less and provide more corrosion resistance than wheels with a polyurethane tread and metal core. They also can withstand exposure to water. These antimicrobial wheels are used on carts and other equipment in facilities where high standards of cleanliness must be maintained, such as medical, pharmaceutical, and food- and chemical-processing facilities.

These wheels have a conductive polyurethane tread that disperses static electricity by letting it flow to the ground. They also have an aluminum core that is lighter and more corrosion-resistant than a steel or iron core. Static-dissipative polyurethane tread on aluminum core wheels are used on carts that will be transporting electronic components and other sensitive equipment. The conductive tread helps dissipate static electricity buildup that can damage the equipment on the carts or injure people who touch the carts. These wheels are used in laboratories, manufacturing facilities, and repair facilities where computers, circuit boards, and other electronic components are handled and static electricity buildup is a concern.

Polyurethane tread on aluminum core wheels weigh less and provide more resistance to rust and corrosion than wheels with a polyurethane tread and iron or steel core. They are used on carts, racks, and similar equipment in environments where the wheels will not be exposed to shock forces, heavy loads, obstructions, poor floor conditions, or standing loads, such as research laboratories, hospitals, food-service facilities, schools, and bakeries.

These polyurethane tread on steel core wheels are sized to fit pallet jacks. They also have bearings that are specifically designed for pallet jack wheels. The wheels' width is equal to or larger than their diameter, which allows them to carry heavy loads for their size. These wheels each have a polyurethane tread that's been chemically bonded onto a steel core. The steel core provides good wear resistance and high load capacities. Polyurethane tread on steel core wheels for pallet jacks are used on pallet jacks, forklifts, and stackers in indoor dock environments.

These wheels have a polyurethane tread and core that are molded as a single piece. This eliminates the risk of the tread and core separating during use. Solid polyurethane wheels can withstand exposure to water.
