DX52D+AZ Galvalume Steel Coil: A Reliable Choice for Modern Construction

In the building and construction industry, material performance directly impacts project longevity and cost efficiency. The DX52D+AZ Galvalume Steel Coil with anti-fingerprint treatment is gaining recognition as a versatile, high-performance solution for roofing, structural components, and industrial applications.

This product features a flat-rolled steel core coated with a unique alloy of 55% aluminum, 43.4% zinc, and 1.6% silicon. This composition combines the barrier protection of aluminum with the sacrificial protection of zinc, offering superior corrosion resistance compared to traditional galvanized steel. With a coating weight range of AZ30 to AZ275 and compliance with international standards such as ASTM A792, JIS G3322, and EN 10147, the product ensures consistent quality across various specifications.

Key Advantages:

  • Enhanced Durability: The aluminum-zinc coating delivers long-term protection in outdoor and high-humidity environments, reducing maintenance needs over decades of service.

  • Versatile Applications: Suitable for corrugated roofing sheets, ventilation ducts, structural components, industrial equipment, automotive parts, and home appliance panels.
