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 % ≥ |
