Galvalume steel sheet（GL）

Introduction of Galvalume steel sheet（GL）

55%-AL Galvalume Steel Coil, also known as GL (Galvalume), is a type of coated steel coil that consists of a continuous hot-dipped metallic coating of 55% aluminum and 45% zinc. The combination of aluminum and zinc provides enhanced corrosion resistance and greater longevity compared to traditional galvanized steel.

The Galvalume coating on the steel coil offers several advantages. Firstly, the aluminum in the coating provides excellent barrier protection against corrosion, even in harsh environments. It acts as a sacrificial layer, protecting the underlying steel from rust and maintaining its structural integrity.

Secondly, the zinc in the Galvalume coating provides galvanic protection by actively corroding to protect any exposed edges or scratches on the steel surface. This sacrificial protection ensures long-lasting performance and prevents the spread of corrosion throughout the steel coil.

55%-AL Galvalume Steel Coil is widely used in various applications, including roofing, wall cladding, structural components, and automotive manufacturing. Its excellent corrosion resistance and durability make it suitable for both interior and exterior applications, even in highly corrosive environments.

Moreover, Galvalume Steel Coil offers excellent heat reflectivity, making it energy efficient in hot climates by reducing the heat transfer into the building or structure. This property can contribute to reducing energy consumption and improving comfort levels.

The 55%-AL Galvalume Steel Coil is available in a variety of thicknesses and widths to suit different project requirements. The coil can be further processed and fabricated into sheets, profiles, or other custom shapes based on specific design needs.

Applications

Such as roofig and flashing, wall cladding, gutters and own pipes, steel house frames, garage doors, vehicular components and other applications where long life is an essential requirement.
