Zinc aluminized sheet

The hot-dip Al-Zn alloy-coated steel sheet is the pre-plating steel plate which is formed by hot-dip plating one Al-Zn plating on two sides of cold-rolled steel plates with various strengths and specifications as substrates, and the plating contains the ingredients in percentage by mass: 55% of Al, 43.5% of Zn and 1.5% of Si, integrating the physical protection and high durability of Al and the electrochemical protective feature of Zn. In addition, patterns with decorative bright silvery grey color and luster and rules are displayed on the surface, presenting embossed feel.
