Chain

Grade 70 Chain

Our transport chains, often referred to as load binding chains, are ideal for applications such as towing and logging. We offer Grade 70 chains, known for their exceptional strength and durability.

Grade 80 Chain

Grade 80 alloy chains are specifically engineered for lifting applications and can be crafted into slings for overhead use, featuring a safety design factor of 4:1.

Grade 100 alloy chains offer a strength that is 25% greater than Grade 80 chains, allowing for the same lifting capacity with a lighter-weight chain. These chains are designed with a safety factor of 4:1, ensuring reliable performance for demanding lifting applications.

Grade 120 Chain

Grade 120 alloy chains are 50% stronger than Grade 80 chains, allowing for the same lifting capacity with an even lighter design. With a safety factor of 4:1, these chains also excel in resisting nicks, pits, and gouges, making them more durable and reliable compared to other grades of chain. This enhanced resilience contributes to longer service life and reduced maintenance needs in demanding lifting applications.
