Introduction:

• Galvalume / Aluzinc Steel Sheet Characteristics and Benefits

The surface of the Galvalume / Aluzinc steel sheet showcases a unique smooth, flat, and attractive spangle pattern with a silver-white base color. This special coating structure provides exceptional corrosion resistance. The typical service life of Galvalume / Aluzinc Steel Sheet and Coils can extend up to 25 years. These sheets possess excellent heat resistance and can be utilized in high-temperature environments up to 315°C. The adhesion between the coating and the paint film is strong, allowing for good processing performance, including stamping, shearing, and welding. Additionally, the surface conductivity is highly efficient.

• Coating Composition and Production Process

The coating comprises 55% aluminum, 43.5% zinc, and 1.5% silicon by weight. The production process for aluminum zinc steel sheet is similar to that of galvanized and aluminum plated steel sheets, involving a continuous melting coating process. The 55% aluminum zinc alloy-coated steel sheet exhibits superior corrosion resistance compared to galvanized steel sheets of the same thickness when exposed to the same environment on both sides. Furthermore, the 55% aluminum zinc alloy-coated steel (55% Alu-zinc Steel) sheet not only offers excellent corrosion resistance but also boasts superior adhesion and flexibility in color-coated products.

By utilizing Galvalume / Aluzinc steel sheets, industries can benefit from their long-lasting durability, heat resistance, and excellent processing capabilities, making them a valuable choice for various applications.

Aluminium-zinc steel-plated light steel offers several outstanding characteristics:

1. Strong Corrosion Resistance: This material provides three times the corrosion resistance of pure galvanising. It remains effective over long periods without changing color, even when exposed to the elements.

2. Aesthetic Appeal: The surface features attractive zinc patterns, making it suitable for use as exterior building panels, such as roofing.

3. Durability: Known as AZ150, aluminium-zinc steel plates have keels that do not change color on exposed surfaces. If exposed to chemical corrosion, a physical reaction on the surface forms an aluminium protective film. This film isolates the keel from chemical substances, preventing rust and protecting the material's integrity.

Protective Mechanism:

The corrosion resistance of aluminium-zinc steel is primarily due to the presence of aluminium. When the zinc layer wears away, aluminium forms a dense layer of aluminium oxide. This oxide layer prevents further corrosion by acting as a barrier, protecting the underlying material from corrosive elements.

Proven Longevity:

Aluminium-zinc plated alloy steel coils have been tested in various atmospheric environments for over 20 years. These tests confirm that aluminium-zinc plated steel provides significantly better edge protection compared to galvanised steel.

Thermal Reflectivity:

Aluminium-zinc plated mild steel boasts a high thermal reflectivity, which is twice that of galvanised mild steel. This makes it an excellent choice for thermal insulation applications.
