Introduction to galvanized sheets

Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective anti-rust method that is often used. About half of the world's zinc production is used in this process.

Classification of galvanized sheets

①Hot-dip galvanized steel plate. A thin steel plate is immersed in a molten zinc bath so that a layer of zinc adheres to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel plates are continuously immersed in a plating bath containing molten zinc to make galvanized steel plates;

②Alloyed galvanized steel sheet. This kind of steel plate is also made by the hot dip method, but it is heated to about 500°C immediately after coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized sheet has good paint adhesion and weldability;

③Electro-galvanized steel plate. This kind of galvanized steel sheet manufactured by electroplating method has good processability. However, the coating is thin and its corrosion resistance is not as good as that of hot-dip galvanized sheets;

④ Single-sided galvanized steel plate and double-sided galvanized steel plate. Single-sided galvanized steel sheet is a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheets. In order to overcome the shortcomings of one side not being coated with zinc, there is another type of galvanized sheet that is coated with a

⑤Alloy, composite galvanized steel plate. It is made of zinc and other metals such as aluminum, lead, zinc, etc., which are alloyed or even composite plated steel plates. This kind of steel plate has both excellent anti-rust properties and good painting properties;

Application scope of galvanized sheets

Galvanized steel sheets are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce, and other industries. The construction industry is mainly used to manufacture anti-corrosion industrial supplies and panels, roof grilles, balcony panels, windowsills, newspaper kiosks, warehouses, rolling shutter doors, heaters, rainwater pipes, etc. used in civil buildings; The light industry uses it to manufacture home appliance shells, civil chimneys, kitchen utensils, etc. the automobile industry is mainly used to manufacture corrosion-resistant parts of cars, etc; Agriculture, animal husbandry and fishery are mainly used as tools for grain storage and transportation, frozen processing of meat and aquatic products, etc; Commerce is mainly used for storage, transportation, and packaging of materials. Galvanized sheets are also used in household appliances, such as refrigerators, washing machines, switchgear, air conditioners, microwave ovens, bread machines, copiers, vending machines, electric fans, vacuum cleaners, etc.
