DX51D Galvanized Steel Plate is a kind of hot-dip galvanizing Plates, and galvanized plate refers to a steel sheets with a layer of zinc plated on the surface. Galvanizing is a frequently used economical and effective method of preventing rust, and about half of the world's zinc production is used in this process. Steel galvanized plate is to prevent the surface of the galvanizing steel plates from being corroded and prolong its service life, and the surface of the steel sheet is coated with a layer of metal zinc. Hot-dip galvanized steel plate is a thin steel sheet in which a thin steel sheet is immersed in a molten zinc bath so that a layer of zinc is adhered to the surface. At present, it is mainly produced by continuous galvanizing process, that is, galvanizing steel plate is made by continuously immersing rolled steel plates in a plating tank in which zinc is melted.With the discovery of the industry, hot-dip galvanized sheet has been used in many fields. The advantage of hot-di…
