[0002] Iron chains are usually divided into two categories according to their uses, namely, jewelry chains and industrial chains. Jewelry chains are divided into side chains, twist chains, mesh chains, parent-child chains, etc. according to their shapes, with many types, while industrial chains are usually manufactured according to different standards and are usually used on ships, electric hoists, cranes, etc.
