Cobalt Chains welded steel chains are high-strength, rollerless chains that are often used in the lumber industry, aggregate and grain conveying, or anywhere that bulk material conveyance is required. Premium, heat-treated sidebars are precision machined and welded to solid, tubular barrels, then connected with induction-hardened pins for maximum strength and durability. Our chains are built to exceed industry standards. Most common sizes are available from on-hand inventory and can be provided with welded attachments and paddles as a turnkey solution to meet your specific material handling needs.
