Wangxia Spring is an experienced spring manufacturer & supplier which offers custom spring, such as garage door spring and compression spring since 2005. 

The company specializes in manufacturing high-strength oil tempered spring steel wire. The oil tempering process can make the spring steel wire obtain good comprehensive mechanical properties, including higher strength, toughness and elastic limit, etc., which greatly improves the service life of the spring. The service life of its products is nearly 18,000 times, which is more durable than springs processed by ordinary processes.

Powder black coating: The powder black coating process not only gives the spring a black texture on the appearance, making the product more beautiful and professional, but also has certain anti-rust and corrosion resistance functions, which can effectively protect the surface of the spring and extend its service life in different environments. Galvanized finish: The galvanizing process is also one of the characteristics of its products. By plating a layer of zinc on the surface of the spring, a dense protective film can be formed, which further enhances the corrosion resistance of the spring, making it very suitable for application environments such as high humidity that are prone to metal corrosion, and improving the adaptability and stability of the product.
