The material properties of aluminum-zinc-plated sheet mainly include corrosion resistance, heat resistance, high reflectivity, and easy painting.

Corrosion resistance: The corrosion resistance of aluminized zinc sheet is one of its important characteristics, mainly because of the protective function of aluminum. When zinc is subjected to abrasion, aluminum forms a dense layer of aluminum oxide, which prevents corrosive substances from further corroding the interior. The corrosion resistance of this material is three times higher than that of pure galvanized sheet, making it excellent for use in architectural roof exterior panels.

Heat Resistance: Aluminum zinc plated steel sheet has good heat resistance and can withstand temperatures in excess of 300 degrees Celsius. This heat resistance allows it to be frequently used in applications that require high temperature environments such as chimney pipes, ovens, luminaires and fluorescent light covers.

High Reflectivity: Aluminum zinc plated sheet has a high thermal reflectivity, almost twice that of galvanized steel. This high reflectivity makes it ideal for use in steel metal roofing applications where energy savings can be realized.

Easy to paint: Aluminized zinc sheets have excellent adhesion to paint and can be painted directly without pre-treatment or weathering. This characteristic makes it suitable for a wide range of applications in the architectural and decorative fields.

These properties make aluminized zinc sheets ideal for architectural, decorative and high-temperature applications.
