Surface state: Galvanized sheet has different surface states due to different treatment methods in the coating process, such as ordinary spangle, fine spangle, flat spangle, non-spangle and phosphating surface. German standards also specify surface levels.
Galvanized coil is inferior to the former in terms of weld ability, coating properties and form ability. For a long time, the stamping form ability, spot weld ability 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.
There is another aspect about the role of the automotive sector, that is, in terms of its own surface material, it should also achieve good aesthetics, since it is outside the material, it will inevitably be achieve a high aesthetic effect.
The automobile surface treatment plate should not only have good corrosion resistance, but also meet the performance requirements of stamping form ability, weld ability, passivation treatment and coating. In North America, heavy-coated galvanized steel sheets are mainly used. In Japan, in addition to ethylene glycol steel sheet, more automobile factories use alloy hot-dip galvanized steel sheet.
