Product Description of Galvanized Steel Sheet:
What Is Galvanized Steel?
The galvanized coil is a thin steel plate in which a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface.Galvanized steel is a surface treatment technique that coats a layer of zinc on the surface of a metal, alloy or other material for aesthetics, rust prevention, and the like. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and soluble in alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor, especially in the atmosphere containing high temperature and high humidity containing organic acid, the zinc coating is easily corroded.
The standard electrode potential of zinc is -0.76V. For steel substrates, zinc coating is an anodic coating. It is mainly used to prevent corrosion of steel. Its protective performance has a great relationship with the thickness of the coating. After passivation, dyeing or coating of the photoresist, the zinc coating can significantly improve its protection and decorative properties.

Hot dip galvanizing (HDG):it is one of the common galvanizing methods. The process is to completely dip iron or steel into molten zinc.
Electro-galvanizing(EG):it is to remove the oil, pickle, and then put into the solution of zinc salt by electrolysis equipment, and connect the negative electrode of the electrolysis equipment, place the zinc plate on the opposite side of the pipe fitting, and connect When the positive electrode of the electrolysis device is turned on, a layer of zinc is deposited on the pipe by the directional movement of the current from the positive electrode to the negative electrode, and the cold-plated pipe member is processed and then galvanized.
Advantage & Application of Galvanized Steel Sheet:
Corrosion Resistance: the zinc coating surface protects the base steel not only by providing barrier to corrosion elements,
but also by the sacrificial nature of the coating. Galvanized steel often remains in working order with little maintenance for
40 years or more.
What are advantages of galvanized steel?
Because of permanently and successive zinc/iron alloy layers, galvanized steel offers many benefits than traditional steels.
