Iron chains are metal chain tools manufactured primarily from iron wire using industrial assembly lines. They are made of metal materials such as iron wire or manganese steel, and the manufacturing process includes mechanical weaving, welding, and heat treatment.
Based on their application, iron chains can be divided into two main categories: jewelry chains and industrial chains. Based on strength, they can be classified into different grades, such as grade 80 high-strength lifting chains.
Industrial iron chains are widely used in elevator compensation devices, security equipment, and other fields.
Furthermore, iron chains can be used as accessories for variable resistance equipment in fitness training, such as in chain bench presses.
