Zinc Aluminium Coated Coil

The aluminum-zinc-plated steel alloy coating is composed of about 55% aluminum, about 43.5% zinc, and about 1.5% silicon.

It has more excellent corrosion resistance, heat resistance, heat reflectivity and other characteristics.

The zinc flower（spangle） on the surface of the aluminum-plated zinc plate is small and uniform, with bright colors and high surface hardness.

Product Details

The aluminum-zinc-plated metallic alloy coating includes about 55% aluminum, about 43.5% zinc, and about 1.5% silicon. Compared with traditional galvanized products, it has more top notch corrosion resistance, warm temperature resistance, warm temperature reflectivity and extraordinary characteristics. The zinc flower（spangle） on the ground of the aluminum-plated zinc plate is small and uniform, with brilliant colours and immoderate ground hardness. It can be blanketed with fingerprint-resistant semi-permeable membranes of severa colours, and is widely applied in own circle of relatives appliances, construction, structure, electric powered and extraordinary industries.
