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.
