What is galvalume steel coil used for?

Galvalume steel sheet (also known as zinc-aluminum-magnesium alloy coated steel sheet) is a special alloy material formed by compounding and curing 55% aluminum, 43.4% zinc and 1.6% silicon elements at high temperatures. With its unique coating structure and superior performance, it is gradually becoming a key material choice in the industrial and construction fields.

This material demonstrates outstanding corrosion resistance. Its anti-corrosion capability can exceed that of ordinary galvanized sheets by more than three times, effectively coping with harsh environments such as humidity, acid rain, and salt fog. Additionally, the surface features a fine and uniform zinc pattern, offering both protective and decorative functions. It is widely used in scenarios where aesthetics and durability are of high importance, such as building exteriors and roof enclosure systems.

• Construction industry: Systems for roofing and walls of steel structure factories, storage facilities, and public buildings;
• Appliance manufacturing: As the external materials for appliances such as air conditioner shells and washing machine panels;
• Transportation: Applicable to automotive parts, cargo box panels, etc.
• Agricultural and industrial facilities: Suitable for scenarios with high requirements for durability, such as grain silos, livestock sheds, and ventilation ducts.

As one of the leading comprehensive metal material service providers in China, ZZ Group has been committed to providing high-quality galvalume coil and related steel products to customers since its establishment in the 1980s. The group’s headquarters is located in Yangpu District, Shanghai, with a registered capital of 200 million RMB. Its business covers multiple fields such as steel trade, processing and distribution, and financial investment. It has been awarded titles such as “One Hundred Trustworthy Enterprises in National Steel Trade and Logistics” and “Top 100 Private Enterprises in Shanghai” for consecutive years, and can provide customers with a full range of services from material supply to technical support.

With the increasing demand for green buildings and durable materials, galvalume steel coil, due to its long-lasting corrosion resistance, aesthetic appearance and environmental friendliness, is becoming an important choice in modern engineering and manufacturing. Choosing reliable galvalume coil suppliers not only concerns the quality of the material, but also relates to the full-cycle cost and sustainability performance of the project.
