Metal Fencing Used AZ90/AZ270 Aluminum Zinc Alloy Coated Steel from Jiangsu

  Metal Fencing Used AZ90/AZ270 Aluminum Zinc Alloy Coated Steel from Jiangsu   Brief Introduction Aluminum Zinc Alloy Coated Steel is a kind of coated steel sheet. 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%, while the remaining is Zn. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.   Production Flow Chart   Specification 1. Thickness: 0.3-0.8mm 2. Width: 914-1250mm 3.
