Galvalume sheet is an alloy structure. Its main components are aluminum, which accounts for about 55%, and zinc is 43.4%. In addition, 1.6% of silicon is added, and zinc is 43.4%. In addition, 1.6% of Silicon is added, and then a sheet is formed after high temperature. Its corrosion resistance is very outstanding, and its durability is also very excellent.

Hot-dip Al-Zn Coated Steel Coil Characteristic:
Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.
Thermal resistance: Common HDG steel plate normally works under 230°C, and has its color changed at 250°C, however, hot-dip Al-Zn coated steel plate can sustain the environment at 315°C 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, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction materials of saving energy.
Resistance to corrosion: Al-Zn coated steel sheet has better performance in corrosion resistance than Gl sheet of the same thickness and its service life is 2-6 times longer than general Gl sheet.
