Galvalume steel coil Standard:ASTM A792/A792M, AS1397,EN10346,JIS G3321

27 Mar.,2025

Galvalume steel coil is a type of steel sheet that has been coated with an alloy of aluminum and zinc. The coating typically consists of about 55% aluminum, 43.4% zinc, and 1.6% silicon. This combination provides the steel with enhanced corrosion resistance, heat reflectivity, and durability compared to traditional galvanized steel.

Galvalume steel coil is a type of steel sheet that has been coated with an alloy of aluminum and zinc. The coating typically consists of about 55% aluminum, 43.4% zinc, and 1.6% silicon.

This combination provides the steel with enhanced corrosion resistance, heat reflectivity, and durability compared to traditional galvanized steel.

 

The combination of aluminum and zinc offers excellent corrosion resistance, as both metals have inherent protective properties. The aluminum provides a self-healing mechanism, forming a thin, transparent oxide layer that prevents further corrosion, while the zinc acts as a sacrificial anode, protecting the underlying steel from rust.

 

Galvalume steel coils are widely used in the construction industry for roofing, cladding, and other applications requiring corrosion-resistant and durable materials. They offer a longer lifespan compared to traditional galvanized steel and are known for their superior resistance to atmospheric corrosion, heat, and sunlight exposure.

 

The price of Galvalume steel coils can be influenced by several factors. Here are some important aspects that can influence pricing:Raw Material CostsProduction and Manufacturing CostsMarket Demand and SupplyCurrency Exchange RatesMarket CompetitionQuality and SpecificationsTrade Policies and Tariffs.

 

Prepainted Galvalume steel coils refer to Galvalume steel coils that have been pre-coated with a paint system. These coils come in various colors and finishes, offering versatility and customization options for different applications. Prepainted Galvalume steel coils provide aesthetic enhancement and additional protection against environmental elements such as UV radiation and moisture. These coils are widely used in applications where both functionality and visual appeal are important.
