Spring Wire with High Quality Is Not Easily Deformed or Broken-Up

Spring wire is a product with very specific technology. It has a strong structure and a good balance of flexibility and tensile strength. According to different surface treatments, spring wire can be divided into: Hot-dipped galvanized wire, electro-galvanized spring wire and PVC coated spring wire. In addition, we also provide stainless steel spring. In the mattress industry, spring wire is used to manufacture springs and hoops. In the Springs' industry, spring wire is used to manufacture mechanical springs. For other usages, our products also have gained a good reputation from the appliance as controlling cable or connecting wire for automobile industry and hard needle.

Spring steel wire is made of stainless steel wire.
