Electrogalvanized Steel Development History

In 1937, the United States established the first continuous hot dip galvanized strip production line, and in 1942, the first continuous electric galvanized strip production line was built in the United States, which has a history of more than 70 years of industrial production.
Hot-dip galvanized products are widely used in construction, home appliances, vehicles and vessels, container manufacturing, electromechanical industry, etc., almost involving various fields of clothing, food, housing and transportation. In recent years, the demand for galvanized steel in the world continues to increase, and the production growth is also very fast, in the United States, Japan and other steel production countries, the proportion of hot-dip galvanized steel in steel has been as high as 13%-15%.
Recently, the automotive industry has paid more and more attention to the service life of materials, and the cold-rolled steel plate with paint can no longer meet the requirements of corrosion resistance. In this case, the hot galvanized sheet with excellent corrosion resistance and low cost began to be widely loved by automobile manufacturers.
The biggest advantages of coated steel plate are excellent corrosion resistance, painting property, decoration and good formability. In recent years, the amount of coated steel plate in automobiles has been on the rise, and it has become the main body of automobile sheet. All countries in the world are studying how to expand the varieties and specifications of coated plates, improve the coating process and improve the quality of the coating, that is, corrosion resistance, resistance to powder stripping, coating property and weldability. The formability of the coated plate is always an important aspect of its application, which mainly depends on the performance of the substrate, coating process and performance and forming process conditions, and can achieve good application results through comprehensive advanced technology.
