Production Of Galvanized Steel Coils By Continuous Galvanizing Process
Galvanized steel coil is a thin steel plate immersed in the molten zinc groove, so that the surface adhesion of a thin layer of zinc sheet steel. Galvanized steel coil can be divided into hot-rolled galvanized sheet coil and cold rolling hot-dip galvanized sheet, Galvanized Steel Coil they are mainly used in construction, home appliances, automobiles, containers, transportation and family business and other fields. In particular, steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.
Galvanized steel Coil features mainly: corrosion-resistant, good surface quality, enrichment in deep processing, economic and practical. Product Standard: Implement enterprise standard/GB.

3. Galvanized steel Coil features mainly: strong corrosion resistance, good surface quality, Galvanized Steel Coil enrichment in deep processing, economic and practical.
4. Galvanized Steel Coil Specifications: The relevant product standards are listed in galvanized steel coil recommended standard thickness, length and width and its permissible deviations. Galvanized steel coil thickness deviation generally in 0.05mm, long width deviation generally in 5mm, Galvanized Steel Coil the thickness of the plate is generally between 0.2-3.2.
Galvanized steel Rolls-classification and use
According to the production and processing methods can be divided into the following categories:
① Hot Dip Galvanized steel plate. The thin steel plate is immersed in the molten zinc groove and the surface is adhered with a thin layer of zinc. At present, Galvanized Steel Coil the main use of continuous galvanizing process production, that is, the rolled steel plate continuously immersed in the molten zinc plating bath made of galvanized steel plate;
② alloyed galvanized Steel sheet. This kind of steel plate is also made by hot-dip method, but after the trough, it is immediately heated to about 500 ℃, so that it produces zinc and iron alloy coated. This galvanized plate has good coating tightness and weldability;
③ Galvanized Steel plate. It has good processability to make the galvanized steel plate by electroplating. But the coating is thinner, the corrosion resistance is inferior to the hot dipping method galvanized plate;
④ single-sided Plating and double-sided zinc galvanized steel plate. Single-sided Galvanized steel plate, that is only in one side galvanized products. In welding, coating, anti-rust treatment, processing, etc., has a better adaptability than double-sided galvanized plate. Galvanized Steel Coil In order to overcome the shortcomings of one-sided uncoated zinc, there is another coating on the other side of the thin layer of zinc galvanized plate, that is, double-sided galvanized plate;
⑤ alloy, clad galvanized steel plate. Galvanized Steel Coil It is made of zinc and other metals such as lead, zinc alloy and even composite plating. This kind of steel plate has excellent antirust property and good coating performance.
