Galvalume Steel Coil Application Scenarios

Coastal high-salinity environments: Such as coastal areas of Japan, Southeast Asia, and the Middle East, offering 2-5 times the corrosion resistance of ordinary hot-dip galvanized steel, suitable for roofing/cladding structures of ports, docks, and offshore platforms, reducing the risk of corrosion from sea breezes.

High-temperature, high-humidity/rainy environments: Such as Southeast Asian tropical rainforests and African rainy seasons, where the coating is less prone to blistering and peeling, suitable for factory buildings, warehouses, and residential roofs, extending service life.

Industrial corrosive environments: Such as chemical parks and areas surrounding power plants, capable of resisting corrosive media such as SO₂ and Cl⁻, suitable for ventilation ducts, equipment casings, and flue gas treatment system components.

Frequently Asked Questions

 

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.
