Term of Manufacturing ProcessPickling : This is a metal surface treatment used to remove impurities, such as rust and scale from Wire rod and coatwire surface to facilitate drawing.


5/5

Patenting : This process is used to improve mechanical properties (Heat treatment to transform steel microstructure into fine one)Drawing : This process guarantees an required diameter and mechanical properties.Stranding : This process to strand the 2 or more wires as per the required application.Bluing : This process is used to improve the elasticity and fatigue limit of drawn steel wire.
