    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.


    Aluminium-zinc-steel plated light steel has quite a few excellent characteristics:

    Comparison of Galvanised and Aluminium Zinc Plating for Light Steel Keels

    Light steel keels can be coated with either galvanised or aluminium zinc plating, each offering distinct characteristics:

    Galvanised Coating: Galvanised light steel keels have a zinc coating whose thickness can vary based on environmental and functional requirements, typically ranging from 120g/m² to 275g/m². The designation Z275 indicates a zinc layer weight of 275g/m² on both sides of the steel sheet.

    Physical Changes with Galvanised Coating: Exposed to year-round atmospheric oxygen, galvanised surfaces may darken over time.

    Aluminium Zinc Plating: Aluminium zinc plated light steel keels exhibit several notable attributes:

    • Strong Corrosion Resistance: Approximately three times that of pure galvanised coatings.
    • Aesthetic Appeal: Features attractive zinc flowers suitable for use as exterior building panels.
    • Designation and Durability: Abbreviated as AZ150, these keels maintain their color over extended periods, resisting chemical corrosion by forming a protective aluminium oxide film. This film isolates the keel from harmful substances, preserving its structural integrity and preventing rust.

    Corrosion Resistance Mechanism: The robust corrosion resistance of aluminium zinc plating primarily stems from aluminium's protective properties. Even when the zinc layer wears away, aluminium oxide forms, effectively shielding the underlying material from further corrosion.

    Long-term Testing and Thermal Properties: Aluminium zinc plated alloy steel coils have undergone outdoor exposure tests for over 20 years in various atmospheric conditions, demonstrating superior protection for cut edges compared to galvanised steel sheets. Additionally, aluminium zinc plated mild steel boasts high thermal reflectivity, twice that of galvanised mild steel, making it an effective thermal insulator.

    This comparison highlights the enhanced durability, corrosion resistance, and thermal properties of aluminium zinc plated light steel keels, making them a preferred choice in demanding applications.
