Galvalume steel coil

Galvalume steel coil is a type of steel coil that has a coating of aluminum-zinc alloy applied to it. This coating consists of 55% aluminum, 43.4% zinc, and 1.6% silicon, providing excellent corrosion resistance and heat reflectivity. This coating provides enhanced corrosion resistance compared to regular galvanized steel coils, making it a popular choice for outdoor structures and roofing. Galvalume steel is also known for its heat resistance and reflective properties, which can help reduce energy costs in buildings.

Gnee Steel is a Chinese galvalume steel coil 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 coil

Galvanized aluminum coils have better corrosion resistance than ordinary galvanized steel, and are especially suitable for use in harsh environments, such as coastal areas or industrial sites.

Aluminum-zinc alloy coating provides good heat resistance, making galvanized aluminum coil suitable for roofing applications where heat reflection is required, helping to reduce cooling costs.

Galvanized aluminum coils last longer than regular galvanized steel, reducing maintenance and replacement costs.

Galvanized aluminum coils can be easily formed and processed into a variety of shapes, making them very flexible in a variety of construction and manufacturing applications.

Galvanized aluminum coils have a metallic sheen that makes them look modern and attractive, making them highly preferred in construction applications.
