Galvanized coil refers to a steel coil coated with a layer of zinc on the surface. Galvanizing is an economical and effective anti-corrosion method that is often used. About half of the world’s zinc production is used in this process. Galvanized steel coil is to prevent corrosion on the surface of the steel coil and prolong its service life. The surface of the steel coil is coated with a layer of metallic zinc. This kind of galvanized steel coil is called galvanized coil.
Hot-dip galvanized steel coil. The thin steel plate is immersed in the molten zinc tank, so that a thin steel plate with a layer of zinc is adhered to the surface. At present, it is mainly produced by continuous galvanizing process, that is, continuous immersion of rolled steel coils in a galvanized bath with molten zinc to make galvanized steel coils;
Alloyed galvanized steel coil. This kind of steel plate is also manufactured by hot dipping method, but immediately after being discharged from the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This kind of galvanized coil has good coating adhesion and weldability;
Electro-galvanized steel coil. The galvanized steel coil produced by the electroplating method has good workability. However, the coating is thinner and the corrosion resistance is not as good as the hot-dip galvanized coil;
Single-sided and double-sided poorly galvanized steel coil. Single-sided galvanized steel coil is a product that is galvanized on only one side. In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized coil. In order to overcome the shortcomings of uncoated zinc on one side, there is another galvanized coil coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized coil;
Alloy, composite galvanized steel coil. It is made of zinc and other metals such as aluminum, lead, zinc, etc. to make alloys and even composite plated steel plates. This kind of steel plate not only has excellent anti-rust performance, but also has good coating performance;
In addition to the above five types, there are color galvanized steel coils, printed coated galvanized steel coils, polyvinyl chloride laminated galvanized steel coils, etc. But currently the most commonly used is still hot-dip galvanized coil.
DX52D+Z Galvanized Steel Coil Features：
1. Galvanized steel coil is widely used in various environments and has a long anti-corrosion life. The anti-corrosion life is different in different environments.
2. The processing cost is low, and the anti-corrosion cost of galvanized steel coil is lower than other paint coatings.
3. Durable, in the suburban environment, the standard galvanized anti-corrosion layer does not need to be repaired and can be maintained for more than 50 years. In cities or offshore areas, the standard galvanized anti-corrosion coating can be maintained for 20 years without repairs.
4. Good reliability. The galvanized layer and the steel are metallurgically combined and become part of the rigid surface, so the durability of the coating is relatively reliable.
5. The coating has strong toughness, and the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.
6. Integrity protection: All parts of the plated parts can be galvanized, even in recesses, sharp corners and hidden places can be fully protected.
7. It saves time and effort. The galvanizing construction speed is faster than other coating construction methods, which can avoid the time required for on-site painting after installation.
