Let's take a brief introduction of the surface treatment of SPA-H weather-resistant steel sheet and its development in the near future.
1. The most common treatment process for the surface of the SPA-H weather-resistant steel sheet is the coating process. This process is mainly to form a zinc layer on the surface of the SPA-H steel sheet. Weather-resistant steel plate can have better corrosion resistance. At present, this technology has certain limitations, so the future development space may also be limited.
2. Another SPA-H steel plate and sheet surface treatment process is a current innovation, namely hot stamping forming steel coating. The technology mainly uses a hot-dip galvanized layer, which can ensure that the zinc layer can maintain stable performance in the process of high temperature or cooling and hot stamping, can prevent the formation of oxide scale, and can play a more complete anti-corrosion effect . At present, this process is widely concerned at home and abroad, and the future development prospects are also immeasurable.
The above two surface treatment processes are currently commonly used for surface treatment of SPA-H weathering steel plates. Our company is always comprehensively improve the ex-factory quality of SPA-H steel sheets. Welcome to come and visit our factory.
