Hot dip galvanized steel sheet is produced by continuous hot dip galvanizing process with hot rolled steel strip or cold rolled steel strip as substrate. Their main characteristics are: strong corrosion resistance, good surface quality, economical and practical.
So what is the purpose of galvanized steel sheet? The following editor will introduce to you.
It is understood that the use of galvanized steel sheet also includes the following aspects: galvanized steel sheet steel products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry industry uses it to manufacture home appliance shells, civil chimneys, kitchen utensils, etc., and the automotive industry is mainly used to manufacture corrosion-resistant parts of cars, etc. ; Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products frozen processing equipment, etc.; commercial use is mainly used as storage and transportation of materials, packaging equipment, etc.
According to production and processing methods, it can be divided into the following categories:
① Hot dip galvanized steel sheet. Immerse the thin steel plate in the melted zinc bath to make a thin layer of zinc adhere to the surface. At present, it is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc plating bath to make the Mild Steel Sheet;
② Alloyed galvanized steel sheet. This kind of steel sheet is also made by hot-dip method, but it is heated to about 500°C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel sheet has good paint adhesion and weldability;
③ Electro-galvanized steel sheet. The galvanized steel sheet manufactured by the electroplating method has good workability. However, the coating is thin, and the corrosion resistance is not as good as the hot-dip galvanized steel sheet;
④Single-sided and double-sided galvanized steel sheets. Single-sided galvanized steel sheet, that 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 steel sheet. In order to overcome the shortcomings of uncoated zinc on one side, there is also a galvanized steel sheet coated with a thin layer of zinc on the other side, that is, a double-sided galvanized steel sheet;
⑤ Alloy, composite galvanized steel plate. It is a steel plate made of zinc and other metals such as lead and zinc alloy or even composite plating. This Mild Steel Sheet has both excellent anti-rust performance and good coating performance.
