Our Red Ductile Steel Wheels range from 4" to 12" and can support up to 20,000 lbs. Known for their exceptional tensile strength of 45,000 PSI, these wheels are ideal for smooth concrete floors and are not suitable for floors with obstacles or automated towing systems. Their high-temperature tolerance ranges from -45° F to 800° F.
Gray Iron Wheels are more affordable but offer a lesser tensile strength of 30,000 PSI. These are great for those on a budget but might require replacement more frequently when used in the same application as Red Ductile Steel Wheels. Temperature tolerance ranges from -45° F to 600° F.
