    Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. Hot dip Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 30 – 275 grams per squaremeter

    Galvanized Steel Coils are produced through a process of metal coating which involves passing cold rolled coils through a kettle containing molten zinc. This process ensures adhesion of Zinc to the surface of the steel sheet. The Zinc Layer provides excellent corrosion resistance and prolong service life.

    Galvanized steel plate is to prevent the surface of the steel plate from being corroded and prolong its service life. The surface of the steel plate is coated with a layer of metal zinc, which is called galvanized steel plate.

    The production line

    Galvanized production line adopts magnesium steel hot dip galvanized process. This process takes cold rolled steel coil as raw material, including cleaning, drying, annealing, galvanizing, cooling,finishing and passivation and then coiling to finished product.


    Our production line enjoy high level of continuous,accurate,large-scale and automatic. The product is widely used in industrial. agriculture and construction areas. When the steel plate surface is coated with zinc,it obtains the advantages of good corrosion resistance, high strength and easy processing etc.

    Advantages of Galvanized

    *Atmospheric corrosion resistance of zinc layer
    *Not easy to rust, long life
    *High temperature oxidation resistance
    *Easy to process
    *Strong hardness, wear resistance
    *The incision is well protected
    *Prevents rust through cathodic protection


    After the hot-dip galvanized steel sheet is pulled out of the zinc pot, the appearance of the crystal grains formed as the zinc layer cools and solidifies is called spangles. The size, brightness and surface morphology of spangles depend on a series of factors, but they are mainly related to the composition of the zinc layer and the cooling method.Galvanized steel coil has the advantages of uniform coating, strong adhesion and long service life.
