CasterHQ's Sirius HD Poly on Aluminum Wheels are used in many applications where the casters and wheels are exposed to water or chemicals. Aluminum is resistant to rust and provides a very strong core for the liquid-cast polyurethane tread. Polyurethane on Aluminum wheels are used in Food Processing Equipment, Food Service, Hospitals, Research Laboratories, Pharmaceutical Laboratories, Bakeries, Schools, Institutional, and industrial applications and environments. Polyurethane is a non-marking tire that is much easier to roll compared to a softer rubber wheel. Polyurethane on Aluminum wheels is great for wash-down applications and wet, corrosive environments. These are great wheels as long as they are not abused, over-loaded, or used in high-impact shock load applications. Polyurethane on Aluminum Wheels is much lighter in weight but has a high weight capacity. We offer multiple polyurethane tread durometers (hardness) for different applications depending on your floor type and use. We offer flat tread and crown treads with multiple bearing options. If you need an application recommendation please contact us for expert advice.
