Galvalume Steel (also known as Aluzinc Steel) is a steel with a special plating technology that is coated with an alloy coating consisting of aluminum (55%), zinc (43.4%) and silicon (1.6%).

Below is a detailed description of Galvalume Steel:

Material Composition:
Main component: alloy plating consisting of aluminum (55%), zinc (43.4%) and silicon (1.6%).
Base material: cold rolled carbon steel.

Performance Characteristics:
CORROSION RESISTANCE: Galvalume Steel has excellent corrosion resistance, with at least twice the corrosion resistance of hot-dip galvanized steel sheets of the same plating thickness in a wide range of environments, from rural climates to severe maritime climates.
Reflective properties: It reflects heat and light twice as well as hot-dip galvanized steel.
Processing properties: Galvalume Steel has a strong adhesion of the coating, which allows it to meet a wide range of processing needs, such as roll forming, bending, etc. It can also be welded, bonded, and mechanically joined using processes similar to those used for hot-dip galvanized steel sheets.
Appearance: Galvalume Steel is also more aesthetically pleasing than galvanized materials.

Areas of application:
Construction: Commonly used for roofing, doors, windows, roller shutters and suspension skeletons.
Automotive: components such as car shells, chassis, doors, trunk lids, fuel tanks and fenders.
Metallurgy: as steel window frame blanks and color coated substrates.
Electrical equipment: such as refrigerator bases and housings, freezers and kitchen equipment.
