Galvanized sheet coil is inferior to the former in terms of weldability, coating properties and formability. For a long time, the stamping formability, spot weldability and surface quality of galvanized GI steel sheets for automobiles have been a problem, which also limits its application in automobile outer panels. Automotive assembly requires 3000-4000 solder joints. Compared with ordinary cold plate, the electrode life of hot-dip galvanized sheet welding is lower, that is, the number of consecutive spot welding of the same electrode is less.

  However, with the development of new technology and new steel grades of hot-dip galvanizing and the improvement of equipment level, the defects of hot-dip galvanized sheet have been greatly improved, so it is more and more used in the field of automobile manufacturing. On the other hand, the zinc material on the entire surface of the galvanized layer is also very demanding in its own right, since this method is used to obtain high corrosion resistance. At this time, its corrosion resistance is naturally its performance, but at this time, due to different manufacturers, it will have its own differences in corrosion resistance.
