PRODUCT DESCRIPTION
For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
1. Normal spangle coating spangle coating
During the normal solidification process of the zinc layer, the zinc grains grow freely and form a coating with obvious spangle morphology.
2.Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted to form a spangle coating as small as possible.
3.No spangle coating spangle-free
By adjusting the chemical composition of the plating solution, there is no visible spangle morphology and a uniform coating on the surface.
4.zinc-iron alloy coating zinc-iron alloy coating
Heat treatment is carried out on the steel strip after passing through the galvanizing bath, so that the entire coating forms an alloy layer of zinc and iron. The appearance of this coating is dark gray, without metallic luster, and it is easy to pulverize during the violent forming process. Coatings that can be painted directly without further treatment except cleaning.

What are the Characteristics of the Galvalume steel coil?
Because it is produced through applying Al-Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn.
>>Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.
>>Thermal resistance: Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvalume steel plate can sustain the environment at 315℃ for long time.
>>High reflectivity: Reflection ability of heat and light is twice as much as those of hot-dip zinc steel sheet, and its
reflectivity is more than 0.70, which is an ideal construction materials of saving energy.
