Galvalume steel sheet/plate

Galvalume steel sheet/plate

Galvalume steel sheet/plate is a hot-dip aluminum-zinc alloy-coated steel sheet composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. This coating makes the steel plate have excellent corrosion resistance and is more weather-resistant and corrosion-resistant than ordinary galvanized steel plate. Galvalume steel plates are commonly used in construction, automobiles, home appliances, and other fields.

Gnee Steel is a Chinese galvalume steel sheet manufacturer. We have the ability to supply AZ165 galvalume to meet customers’ requirements for use in highly corrosive areas. We ensure that the weight of the metallic coating does not cut corners, and we have the equipment to detect it.

Features of Hot Sale Galvalume steel sheet/plate

The aluminum-zinc alloy coating of galvalume sheets provides excellent corrosion resistance and has a longer service life than traditional galvanized steel sheets. This makes it ideal for use in outdoor environments and harsh weather conditions.

The aluminum-zinc alloy coating makes the galvanized plate have good high-temperature resistance and is suitable for applications in high-temperature environments.

Due to its high-quality coating, galvalume has excellent weathering resistance and is not easily fade or age, maintaining its long-term beauty.

The aluminum-zinc alloy coating makes the galvalume plate lighter in weight and higher in strength, easy to handle and install, and not easy to be deformed or damaged during use.

Galvalume has good weldability and can be easily combined with other materials, making it suitable for various processing and manufacturing processes.
