Cost iron, sometimes referred to as semi-steel, offers the highest tensile strength in the industry. (30,000 psi). These cast iron wheels are constructed of premium cast iron for high capacity applications and impact strength. The wheels have heavy cross section castings for heavy duty use, are abrasion resistant and provide a long service life.  They require minimal effort for start-up and push loads.

• Cast-Iron/Semi-Steel, offers strong, durable, cost effective solution for heavy loads.
• Hard tread rolls easily and offers high abrasion resistance.
• Tread face precisely machined for a smooth ride
• Tread edge is machined round.
• Hardness: Brinell 145 Tensile strength of 30,000 PSI.
• Keyway and/or set screws available
• Temperature range: -45 F to 600 F.

Note: It should be taken into account when ordering that semi-steel wheels are not an ideal selection for concrete floors.
