Spring steel wire is one kind of steel wire used for spring or wire form.  According to the  different application area of spring, the quality  requirement of spring steel wire has a  very big difference. We make  various spring steel wires for mattress, bumper,  suspension spring,  engine valve, camera shutter and so on. The steel spring wire can also  be classified into 4 main types based on manufacturing technology:  galvanized spring s teel wire, patented spring steel wire, oil tempered  steel wire and general type wire.

The raw materials for spring steel wire include 65#,70#,65Mn, 82B,72A,72B steel  wire rod.
