Hot-dip galvanizing products

In 1937, the United States established the first continuous hot-dip galvanized strip production line. In 1942, the first continuous electrogalvanized strip production line was built in the United States. It has been in production for more than 70 years since it entered industrial production.

Hot-dip galvanizing products are widely used in construction, home appliances, vehicles and ships, container manufacturing, and electromechanical industries, and are involved in all areas of clothing, food, housing and transportation. In recent years, the demand for galvanized steel sheets in the world has been increasing, and the output growth has also been rapid. In the major steel producing countries such as the United States and Japan, the proportion of hot-dip galvanized steel sheets in steel has reached 13%-15%.galvanized steel coil manufacturers

Recently, the automotive industry has paid more and more attention to the service life of materials, and the use of painted cold-rolled steel sheets has not been able to meet the corrosion resistance requirements. In this case, hot-dip galvanized sheets, which are excellent in corrosion resistance and low in cost, are generally favored by automobile manufacturers.

The greatest advantages of coated steel sheets are excellent corrosion resistance, paintability, decorativeness and good formability. In recent years, the amount of coated steel sheets in automobiles has been on the rise, and has become the main body of automotive sheets. Countries all over the world are studying how to expand the variety and specifications of coated plates, improve the coating process and improve the quality of coatings, namely corrosion resistance, anti-powdering, coating, and weldability. The formability of the plate is always an important aspect of its application, which depends mainly on the substrate properties, coating process and performance and forming process conditions, and can be achieved through comprehensive advanced technology.
