Ductile steel wheels are the next level up in capacity & durability from cast iron wheels. Made from a combination of alloys that provide excellent tensile strength, these wheels come with extra thick treads, hubs & walls. For maximum capacity & durability, check out our premium forged steel wheel casters.
While ductile steel is very resilient, it is tough on floors & could lead to floor damage. For heavy duty floor protective wheels, be sure to check out our polyurethane wheels.
