Over the past two decades, hot-dip galvanizing technology, equipment and corresponding control means have great development so that galvanized steel coils meet the harsh requirements of automotive panel and home appliances. It is not only cheaper than electro-galvanized alloy steel coil but also has better corrosion resistance.

After 20 years of research, the above technical problems and technical requirements of the process equipment has been basically solved and began to be widely used for cars. This will not only greatly improve the work of the car, but also prolong life and save energy.
