Guaranteed Quality 0.15-2mm Thickness Roll Cold Rolled Galvanized Steel Coil

Guaranteed Quality 0.15-2mm Thickness Roll Cold Rolled Galvanized Steel Coil
 
Galvanized Coil has excellent performance, possessing ideal comprehensive properties of corrosion resistance, formation and coating. It is produced by passing the steel sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristic.

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.
