Description

Galvanized steel plate is a material that prevents corrosion by coating a layer of metallic zinc on the surface of the steel plate, thus effectively extending the service life of the steel plate. This specially treated steel plate is usually called galvanized sheet. The production process and processing method of galvanized sheet can be classified according to different needs and standards, which can be mainly divided into the following types:

Hot-dip galvanized steel sheet: This is a common method for the production of galvanized sheet, which involves dipping a thin steel sheet into a molten zinc bath in order to form a uniform zinc layer on the surface of the steel sheet. This process usually uses a continuous galvanizing process, that is, the steel plate is passed and rolled continuously in a specially designed zinc bath to ensure that each part is evenly coated with zinc. The galvanized sheet produced by this method has good corrosion resistance and long service life.

Alloying of galvanized steel: This method is further developed on the basis of the hot dip method. After the steel plate is coated with zinc, it is immediately heated to a high temperature of about 500 ° C, the purpose of doing so is to promote the alloying reaction between zinc and iron to form a zinc-iron alloy film. This alloyed galvanized sheet not only has excellent corrosion resistance, but also has good coating adhesion and weldability, which makes them very popular in industrial applications. The thickness of galvanized sheet can range from 0.18 mm to 20 mm, of which 2 mm thick galvanized sheet is one of the common specifications on the market, and the size of the hot dip galvanized sheet can also be customized according to different needs.

As an economical and effective anti-corrosion material, galvanized steel plate has a wide range of production processes and applications, which can meet the needs of different industries and environments for corrosion resistance. Whether in the construction industry, automotive manufacturing or in areas such as household appliances, galvanized steel plays an important role in protecting all kinds of equipment and structures from corrosion.
