To put it bluntly, galvanized steel plate coats with a layer of zinc on the surface of the steel plate, so that it can have a certain level of corrosion resistance.
This kind of production method can also reduce the consumption of zinc in the world.
The main purpose of it introduces in detail:
1. non-aluminum alloy hot-dip galvanized steel strip
DC5XD series products: can use for general use, and can also use for deep drawing and biting.
The larger the zinc content on the surface, the better the corrosion resistance;
the smaller the amount of hot-dip galvanizing on the surface, the better the processing performance.
SXXXGD series products: can used for construction, it has excellent processing performance and corrosion resistance.
HXXXPD+Z series products: including high alloy steel, phosphorus content steel, and hard-bottomed steel, which have excellent processing performance and corrosion resistance.
2. Alloyed hot-dip galvanized steel strip
DCXXD+ZF series products: can use for construction, stamping die, and cold forming.
The galvanized steel sheet of this material has more excellent welding performance and coating performance, but it is easy to cause detachment in the process of processing.
Detailed introduction of galvanized steel sheet classification:
1. Alloyed galvanized steel sheet:
The profiled steel plate produced by the hot-dip method has excellent electric welding weldability and adhesion performance.
2. Hot-gold galvanized steel sheet:
This is also a thin steel sheet with a very thin layer of zinc adhered to the surface, and its processing technology is a continuous hot-dip galvanizing method.
3. Electro-galvanized steel:
The plug-in method use to hot-dip galvanize the steel plate, but the zinc plated by this method is relatively thin and the corrosion resistance is relatively poor.
4. Single-layer galvanized steel sheet:
Galvanizing only applies to one side of the steel plate, whether for processing, spraying, or electric welding, the adaptability better than that of double-sid galvanized steel.
5. Two-sided poor galvanized steel sheet:
Single-layer galvanized steel sheets may have some defects.
In order to better get rid of such defects, a very thin layer of zinc will continue to plate on the other side of the steel sheet.
This is the two-side difference galvanize steel sheet.
6. Compound galvanized steel:
In addition to the internal raw materials, stainless steel,
