Zinc Coating Sheet Galvanized Steel Coil Z60/Z180
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.
