Benefits

These casters offer a hygienic, corrosion-resistant mobility solution for environments where moisture, chemicals, or toxins are present. The polymer design minimizes rust and maintenance, helping equipment stay reliable longer in demanding spaces such as labs, chemical plants, healthcare facilities, and food-service environments.

The MetroMax i Stem system gives you a choice between a lighter 300 lb per caster option and a heavier 800 lb per caster resilient variant with metal hubs, so you can match load needs without sacrificing corrosion resistance. This means fewer replacements, less downtime, and smoother transport of heavy loads across wet floors or damp storage areas.

Why choose these over alternatives? The metal-free option reduces contamination risk and maintenance in harsh environments, while the resilient version adds robust load capacity for heavier carts and shelving. For best results, pair the standard polymer casters for lighter-duty tasks and reserve the resilient metal-hub version for higher-capacity applications.

Practical tips: assess the typical load per cart plus the anticipated environmental exposure (moisture, cleaners, or chemicals) to determine which capacity suits your needs. Regularly inspect the polymer surfaces for wear, and replace with the appropriate version when load demands increase or exposure intensity changes.
