1.GENERAL INTRODUCTION
Galvanized steel means that to prevent the surface of the steel from being corroded and prolong its service life, a layer of metallic zinc is coated on the surface of the steel. This kind of zinc-coated steel is called galvanized steel.
Galvanized steel is chemically treated to prevent corrosion. This steel is coated with a layer of zinc because it is difficult for rust bacteria to corrode this protective metal material.
The main way to make steel resistant to corrosion is to add other metals, such as zinc. After the steel is immersed in zinc, the chemical reaction will cause the zinc to be permanently plated on the steel. Therefore, zinc not only covers the steel paint but has become a part of it.
2.Different Methods Of Galvanizing
Surface galvanizing is one of the most commonly used methods in the surface treatment of steel products. Since its birth, it has been widely used in all walks of life. In practical applications, the main methods of galvanizing can usually be divided into hot-dip galvanizing and electro-galvanizing.
l Electro-Galvanized
Electro-galvanizing is also called cold galvanizing, which is the process of using electrolysis to form a uniform, dense, and well-bonded metal or deposition layer on the surface. The workpiece is placed in the electrolyte, and the current flows through the electroplating solution so that the electroplated metal is deposited and deposited on the workpiece to form a coating.
The thickness of the coating is usually 4-12 microns, which is much smaller than the thickness of the coating produced after hot-dip galvanizing.
l Hot-Dip Galvanized
Hot-dip galvanizing is currently the most widely used galvanizing method. It can make the workpiece get a thicker galvanized layer. Generally, the average thickness of the zinc layer can reach 50 microns or more, and the coating is uniform and coated.
Hot-dip galvanized steel has the advantages of strong strength and long service life.
3.APPLICATION
Galvanized steel coils are mainly used in the construction, light industry, automobile, agriculture, animal husbandry and fishery and commercial industries. Among them, the construction industry is mainly used for the manufacture of industrial and civil building anti-corrosion roof panels, roof grilles, etc.; light industry is used for the manufacture of household appliances shells, civil chimneys, kitchen appliances, etc., the automotive industry is mainly used for the manufacture of corrosion-resistant parts of automobiles, etc.; agriculture, animal husbandry and fishery is mainly used for grain storage and transportation, meat, aquatic products refrigeration processing tools, etc.; commerce is mainly used for material storage and transportation, packaging tools, etc.
