Hot-dip aluminium-zinc coated steel plate is a pre-coated steel plate obtained by hot-dip plating a layer of Al-Zn coating on both sides of a cold rolled steel plate of various strengths and thicknesses as a substrate, with a mass percentage of 55% Al (aluminium), 43.5% Zn (zinc) and 1.5% Si (silicon) in the composition of the plated layer, which combines the physical protection of Al and high durability as well as the electrochemical protection of Zn, and has the strength and plasticity of the base steel, and the corrosion resistance of the coating. The material has the strength and plasticity of substrate steel and the corrosion resistance of plating, which protects the metal substrate from internal corrosion. In addition, the surface has a highly decorative bright silver grey colour and regular patterns with a sense of embossment.

Aluminum-zinc-plated light steel exhibits several outstanding characteristics:

Strong Corrosion Resistance: It provides corrosion resistance three times stronger than pure galvanizing. The surface features attractive zinc flowers and is suitable for use as exterior panels on building roofs.
Long-term Color Stability: Designated as AZ150, aluminum-zinc-plated steel plates maintain their color over extended periods, resisting chemical corrosion. When exposed, a physical reaction occurs, forming a protective aluminum oxide film on the surface. This film isolates the steel from external chemicals, preventing rust and preserving the integrity of the material.
Mechanism of Corrosion Resistance: Aluminum primarily contributes to its robust corrosion resistance. In the event of zinc abrasion, aluminum reacts to form a dense layer of aluminum oxide, effectively preventing further corrosion of the underlying steel.

These properties make aluminum-zinc-plated light steel a durable and protective choice for various applications, particularly where corrosion resistance and aesthetic appeal are crucial.
