Don't take chances with downtime: get shredder components and assemblies that outlast the rest. Few U.S. foundries have the capability to produce and assemble a shredder rotor in a vertically integrated manufacturing facility like you'll find at Columbia Steel. Whether you're replacing a standard rotor, components, or need something custom, Columbia Steel engineers will work closely with you to meet your specific requirements with improved design and optimum alloy selection. Our wear parts and shafts are manufactured in alloys that excel in the toughest applications. From spider arms and end disks, to rotor shafts, we choose alloys for high strength, high impact-resistance, and maximum reliability. If you can't afford downtime in your operation, give Columbia a call for all your rotor wear part needs.
