EN 10346 DX51D AZ Galvalume Steel Coil Application Scenarios
The AZ aluminum-zinc coating on this steel coil forms a dense aluminum oxide protective film on the surface, which can resist corrosion from rainwater, condensation, and mild industrial exhaust gases. Therefore, it can be used in coastal areas with high humidity and suburban areas with light industrial pollution, but it is not recommended for extreme corrosive environments involving prolonged contact with strong acids, strong alkalis, or high-concentration salt spray.
Working environments requiring forming and processing:
Its base material has excellent cold-forming properties, so it can be used in production environments that require bending, stamping, and stretching. The coating is not prone to peeling or cracking during processing.
Construction industry:
It can be used as a building envelope material, such as the base material for roof panels and wall panels of light steel villas, or the keel
components of prefabricated houses;
It can also be used to manufacture metal fittings for building drainage systems, such as rain gutters and downpipes.

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.
