Hongye established in 1995, focused on high-end carbon steel wire production many years and has already formed a unique set of high-efficient crafts.Our steel wire production technology is advanced, and from raw material purchase ,the wires production,to the goods delivery ,we always have a very strict system to control all the procedures.All of this helps to make sure our quality to be first-class.

Medium Carbon Steel Wire is made of Shagang wire rod. There are many kinds of the usages of round carbon spring steel wire.

Such as:Mechanical Equipment, Engineering Vehicle, Motor Vehicle, Motorcycle, Accumulator Car, Bicycle, Fitness Equipment, Elevator, Steel Wire Screen, Mattress And Sofa, Umbrella Frame, Electronic Products,ect.

Spring steel wire diameter is range from 0.20mm to 12.50mm.

The Mattress and Sofa Steel Wire we produce follows the following standards.

DIN 17223 GRADE A B C D 

EN 10270 SL SM SH DM DH 

JIS G3521 SWA SWB SWC

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

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