Steel plate is one of the important building materials and industrial materials, and it is also one of the important steels. There are many types of steel plates, all of which are rolled from different types of steel through different processes. As a construction or industrial material, steel plate often faces the problem of surface corrosion and rust. In order to enhance the anti-corrosion performance of the steel plate, a layer of zinc is plated on the surface, thereby producing a galvanized steel plate. Galvanizing on metal surfaces is currently the most common method for enhancing corrosion resistance of steel, and it is also the lowest cost method. Therefore, most of the steel plates have to be galvanized and then used as plates in the field of construction and industrial production. Let me introduce one of them, the hot-dip galvanized steel plate.
About galvanized steel sheet and hot-dip galvanized steel sheet:
Zinc is a chemical element that is recognized as a relatively stable chemical element in the chemical industry. It is very stable in various environments, that is, it is not easy to chemically react with other substances. Therefore, almost half of the output of zinc is used. Galvanized treatment of metal surfaces. The anti-corrosion and rust resistance of the galvanized steel plate is greatly enhanced, the surface is more shiny, and the service life is greatly enhanced. There are many types of galvanized steel sheets. According to their different production and processing methods, they can be divided into hot-dip galvanized steel sheets, alloyed galvanized steel sheets, electro-galvanized steel sheets, single-sided and double-sided differential galvanized steel sheets, alloys, There are different types of composite galvanized steel sheets, among which hot-dip galvanized steel sheets are the most widely used.
The galvanizing treatment method of hot-dip galvanized steel plate is a relatively traditional galvanizing method. Simply put, the steel plate is directly immersed in the molten zinc bath, so that a layer of zinc is attached to the surface of the steel plate. The rolled steel sheet in coils is directly subjected to continuous galvanizing treatment. Although the cost of this method of galvanizing the steel sheet is relatively low, it also has some disadvantages, which are mainly reflected in the fact that the surface galvanized is easy to fall off, and then white spots and black spots appear. At present, hot-dip galvanized steel sheet has become a relatively conventional material in many fields, and it is widely used in construction, home appliances, automobiles, machinery, electronics, light industry and other fields.
