ASTM A792 Galvalume Steel Coil Application scenarios

Highly corrosive outdoor environments:
Coastal areas: With high-salinity sea breezes and moisture, the dual corrosion resistance of this steel coil can withstand salt spray corrosion, making it suitable for exterior walls and roofing materials of coastal buildings, or the casings of outdoor facilities in coastal areas.

High-temperature environments:
Automotive exhaust system components, internal components of ovens, and inner linings of industrial drying equipment, which can withstand continuous high temperatures while maintaining stable performance.

Prefabricated building enclosure components, such as wall and roof materials for modular homes, requiring a balance of processability, corrosion resistance, and aesthetics.

Building scenarios with energy-saving requirements:
Can be used as roofing and exterior wall materials for energy-efficient buildings, reducing building air conditioning energy consumption due to its high reflectivity.

1.what is the difference between galvalume and galvanized steel

The core difference between aluminum-zinc coated steel sheets and galvanized steel sheets lies in the composition, structure, and performance of the coating. The former has an alloy coating of 55% aluminum + 43.4% zinc + 1.6% silicon, offering both barrier protection and sacrificial protection, with superior corrosion resistance, heat resistance, and reflectivity; the latter has a pure zinc coating, primarily providing sacrificial anode protection, and is lower in cost and easier to paint, making it suitable for general anti-corrosion applications.
