Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Galvanized steel coil
Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
Galvanized steel is to prevent the steel plate surface from corrosion to extend its service life, in the steel plate surface coated with a layer of metal zinc, the zinc coated steel plate are called galvanized sheet.
According to the production and processing methods can be divided into the following categories:
(1) hot dip galvanized steel. Thin plate in melting zinc bath, make its surface adhesion of a layer of zinc sheet. At present mainly adopts continuous galvanizing process, namely the continuous roll of steel plate in the melt zinc plating tank made of galvanized steel sheet;
(2) the alloying of galvanized steel. This kind of steel plate is made by hot dip method, but after the slot, immediately heated to a temperature of about 500 ℃, it make the generation of zinc and iron alloy membrane. This kind of galvanized sheet with good coating of sex and weldability;
(3) electric galvanized steel. Made this kind of galvanized steel plating method has good workability. But the coating is thinner, the corrosion resistance and the method of hot dip galvanized sheet
(4) the single side and double difference galvanized steel plating. Single galvanized steel, that is, only in a galvanized products. Material in the antirust processing, welding, painting, machining, etc., two-sided galvanized sheet better adaptability. In order to overcome the single side not the shortcoming of zinc coating, and one in the other side is coated with a thin layer of zinc galvanized sheet, namely double difference galvanized sheet;
(5) alloy and composite galvanized steel. It is made from zinc and other metals such as aluminum, lead, zinc alloy and composite plating of steel plate. This steel has excellent rust resistance, and good coating performance, Besides the above five kinds of color galvanized steel plate, printing and coating of galvanized steel sheet, PVC laminated galvanized steel sheet, etc. But still by far the most commonly used for hot dip galvanized sheet.
