DX54D+Z Galvanized Steel Coil


Galvanized sheet refers to the steel plate coated with a layer of zinc. Galvanizing is an economical and effective antirust method which is often used. About half of the world's zinc production is used in this process. Galvanized steel sheet is to prevent corrosion on the surface of steel plate and prolong its service life. A layer of metal zinc is coated on the surface of the steel plate, which is called galvanized steel plate.

    Advantages

    1.Available for customized specification on customers’ request.
    2.Perfect Corrosion Resistance. The service life of galvalume is 3-6times as long as that of galvanized surface.
    3.Perfect Processing Performance. Fully meet the requirement of roll processing, stamping, bending, ect.
    4.Perfect Light Refelectivity. The ability of reflecting light and heat is twice that of galvanizing.
    5.Perfect Heat Resistance. Galvalume products can be used at 315 degree Celsius for a long time without discoloration.
    6.Excellent adhesion between the paint. Easy to paint and can be painted without pretreatment and weathering.

     

     

    Galvanized Steel Coil Types

    According to the processing method, we divide galvanized steel into the following categories:

     

    1. Hot-dip Galvanized Steel Coil

    As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:

    1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.

    2) The cost of hot-dip galvanizing is cheap.

     

    2. Electro-galvanized Steel Coil

    Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
