Al-Zn Coated Steel Sheet

Hot-dip Zinc Aluminum coated steel sheet and strip

Hot-dip Al-Zn coated steel is a kind of coated steel. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, Zn 43.4%. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn.

MOQ: 20 tons

Hot-dip Zinc Aluminum coated steel sheet and strip

 

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.
