Hongye focused on high-end Carbon Steel Wire production Our main products include low carbon steel wires, medium carbon steel wires, high carbon steel wires, spoke wires, spring wires, mattress wires, sofa wire, mesh wire, garage door spring wire, etc .From raw material purchase ,the wires production,to the goods delivery ,we always have a very strict system to control all the procedures.We can produce our Spring Steel Wire according to DIN, JIS, ASTAM, ISO, GB/T, and YB/T.

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

Black Steel Wire diameter is range from 0.20mm to 12.50mm.

The production process of Cold Drwan 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.
