55% Alu + 43.5%zinc +1.5% Si Steel Coil
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 Plating:
- Exceptional Corrosion Resistance: Aluminium zinc-plated light steel offers corrosion resistance three times greater than pure galvanised steel. It features attractive zinc flowers on the surface, making it suitable for use as exterior building panels. The abbreviation AZ150 denotes its designation.
- Long-Term Color Stability: Aluminium zinc-plated steel maintains its appearance over time. When exposed to chemicals, a physical reaction forms an aluminium protective film on the surface, isolating the keel from harmful substances and preventing rust.
- Mechanism of Corrosion Resistance: The superior corrosion resistance is primarily due to aluminium. When the zinc layer wears away, aluminium forms a dense layer of aluminium oxide, protecting the underlying material from further corrosion.
Outdoor Durability:
- Aluminium zinc-plated steel coils have been tested in various atmospheric environments for over 20 years. These tests confirm that aluminium zinc-plated steel provides significantly better protection for cut edges compared to galvanised steel.
Heat Reflectivity:
- Aluminium zinc-plated mild steel boasts high thermal reflectivity, nearly twice that of galvanised mild steel, making it an ideal choice for thermal insulation.
In summary, aluminium zinc-plated light steel keels offer superior scratch resistance, durability, and thermal properties compared to galvanised light steel keels, making them a more reliable choice for various applications.

Detailed Parameters:
| SURFACE TREATMENT | DESCRIPTION OF USE |
| CHROMATE PASSIVATION(C) | Surface treatment for high-strength steel plates after hot-dip plating to reduce white rust during transport and storage |
| Chrome-free passivation(C5) | Surface treatments that require limiting the amount of hexavalent chromium, etc. in passivation solutions that are harmful to the environment and humans |
| Anti-finger print(N) | Surface treatment after the passivation process, which acts as a lubricant during processing, prevents fingerprints from staining during operation, and prevents premature blackening of the surface during use. |
| Chrome-free and fingerprint resistant(N5) | Surface treatment after the passivation process, in the process of lubrication, to prevent the operation of the fingerprint staining, to prevent the use of the surface of the process of premature blackening, and at the same time, the requirement to limit the fingerprint-resistant film harmful to the environment and human body, such as hexavalent chromium content |
| Oiled(O) | Surface treatment added after the passivation process to further reduce rusting during long-distance transport and long-term storage |
| Usage | Steel Grade | Yield Strength(MPa) | Tensile Strength(MPa) | Elongation at break A80mm % ≥ |
