Analysis of Processing Details of Galvanized Sheet
The galvanized sheet is to prevent the surface of the steel sheet from being corroded and prolong its service life. The surface of the steel sheet is coated with a layer of metallic zinc. This kind of galvanized steel sheet is called a galvanized sheet or galvanized steel sheet. Construction, electronics, agriculture, animal husbandry and fishery, light industry, automobiles, household appliances, commodity packaging, and other industries. It is so widely used, what are its passing methods? Next, let the professional China color-coated corrugated roofing sheet manufacturers introduce the processing methods of galvanized sheet products for you.
1. Alloyed galvanized sheet
This kind of steel plate is also made by hot-dip galvanizing, but it is heated to about 500 ° C immediately after leaving the trough to form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability.
2. Single-sided plating and double-sided galvanized sheet
Single-sided galvanized steel, that is, products that are galvanized on only one side. In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than a double-sided galvanized sheet. In order to overcome the shortcomings of uncoated zinc on one side, there is a high quality galvalumed steel sheet coated with a thin layer of zinc on the other side, that is, a double-sided galvanized sheet.
3. Hot-dip galvanized sheet
The steel sheet is immersed in the molten zinc bath so that a thin layer of zinc sheet adheres to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, the coiled steel sheet is continuously immersed in a zinc-melted plating tank to make a galvanized steel sheet.
4. Alloy, composite galvanized sheet
It is a steel plate made of zinc and other metals such as lead and zinc alloy or even composite plating. This steel plate has both excellent anti-rust performance and good coating performance. In addition to the above five types, there are color galvanized steel sheets, printed coating galvanized steel sheets, polyvinyl chloride laminated galvanized steel sheets, etc.
5. Electro-galvanized sheet
The use of electro galvanizing method to produce such a galvanized steel sheet has good workability. However, the coating is thinner and the corrosion resistance is not as good as the hot-dip galvanized sheet.
