Hot-dip Galvanized Coil Performance

The hot dip galvanized steel coil for sale has good corrosion resistance, so the construction industry is still the largest user of hot-dip galvanized coils.

Compared with the cold plate and the galvanized sheet, the hot-dip galvanized strip has the same weldability, coating performance, and formability as the former.

For a long time, the press formability, spot weldability and surface quality of hot dip galvanized steel coil for sales for automobiles have been a problem, and their application on automobile outer panels has also been limited. When assembling a car, it is necessary to weld 3000-4000 points. Compared with the cold plate, the electrode life is low when welding the hot-dip galvanized plate, that is, the number of consecutive spot welding of the same electrode is low.

However, with the development of new hot-dip galvanizing processes and new steel grades, the level of equipment has improved, and the inadequacies of hot dip galvanized steel coil for sales have been greatly improved, so there are more and more applications in the automotive industry.
