Our company specializes in Carbon Spring Steel Wire, Spoke Wire, Free Cutting Steel Wire (for nipple making) and steel wire for vehicle door locks manufacturing. We acquired most advanced and precise technology and have raised a host of skilled workers and a good management team. System of perfect quality control and first-class equipments are used in our production.

There are many kinds of the usages of Spring Steel Wire.

Such as:agricultural machines,compression spring,torsion spring,die springs,extension spring,strip&wire forming springs

High Carbon Spring Steel Wire diameter is range from 0.20mm to 12.50mm.

The production process of Helical Spring Steel Wire is roughly divided into 4 parts:

firstly,removing the oxide that layer on the wire rods;next it is hydrochloric acid cleaning phosphating,;saponification;and drawing wires ; 

After production, we can do tensile strength test,reduction of area test,elongation test,torsion test,wrapping test ,bending test,ect.to test the quality of the product.
