Light House Build AFP Galvalume Steel GL 55% Aluzinc 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.

Characteristics:

Corrosion Resistance: Zinc is highly chemically active, forming a thin, dense layer of alkaline zinc carbonate film on its surface at room temperature, which prevents further oxidation. Similarly, aluminum forms a layer of insoluble oxides in the air, providing effective barrier protection.

Heat Resistance: Aluminum-zinc plated sheets can withstand high temperatures up to 315 degrees Celsius, making them suitable for high-temperature environments.

Reflectivity: Aluminum-zinc coated sheets have high reflectivity, with a heat reflectivity nearly twice that of galvanized steel. This makes them ideal for use on steel metal roofs, contributing to energy savings.

Ease of Painting: Aluminum-zinc-plated sheets have excellent adhesion properties between the sheet and paint, allowing them to be painted without the need for pre-treatment or weathering.
