Grade 80 Chain (also known as G80 Chain) is a high-strength alloy steel lifting chain designed for heavy-duty lifting, hoisting, and load securing applications. It is widely used in chain slings, cranes, hoists, and material handling equipment across industries such as construction, mining, manufacturing, marine, and logistics. Grade 80 chains are known for their excellent strength, toughness, and durability, making them suitable for demanding lifting operations.
