Galvalume Steel Roofing Sheets (AZ coated steel panels) are high-performance metal roofing materials coated with an alloy of 55% aluminum, 43.5% zinc, and 1.5% silicon. They are widely used in industrial buildings, commercial warehouses, agricultural structures, and residential roofing, offering superior long-term corrosion resistance and excellent heat reflectivity.

As a leading factory direct supplier, XQJ Metal provides a comprehensive range of high-performance galvalume roofing and wall cladding sheets tailored for global construction requirements:

• Main Substrates & Standards: AZ150, AZ185 coatings, ASTM A792, and JIS G3321 standards.

• Profile Types: Corrugated wave profiles, trapezoidal roof panels, and concealed-fix structural roofing systems.

• Key Advantages: Outstanding heat resistance, exceptional anti-corrosion lifespan (often 3-6 times longer than standard galvanized sheets), lightweight design, and high structural strength.

Frequently Asked Questions (FAQ):

• Q: What is the main difference between Galvalume and Galvanized roofing sheets? A: Galvanized sheets use a pure zinc coating, whereas Galvalume sheets use an aluminum-zinc alloy coating. Galvalume provides significantly better heat reflectivity and long-term corrosion protection in harsh atmospheric environments.

• Q: Do you offer custom lengths and anti-condensation treatments? A: Yes, we provide custom cut lengths tailored to 20ft/40ft containers and optional anti-condensation non-woven fleece backing on the underside.
