Hot Dipped Galvalume Steel Coil DX51D+AZ for construction Materials

Hot Dipped Galvalume Steel Coil DX51D+AZ for construction Materials

Galvalume Steel Coil is coated with a unique aluminum-zinc-silicon alloy—comprising 55% aluminum, 43.4% zinc, and 1.6% silicon—cured at high temperature to form a highly protective layer. This advanced coating offers exceptional corrosion resistance, outperforming standard galvanized steel by up to 6 times, making it ideal for demanding building applications.

Product Specifications

Applications

• Construction & Architecture: Ideal for high-durability roofing, wall cladding, and structural components. The exceptional corrosion resistance ensures long-term aesthetic appeal and structural integrity, even in harsh environmental conditions.

• Manufacturing & Industrial Sector: Perfect for manufacturing HVAC duct systems, industrial appliances, and electrical enclosures. The dry, unoiled, and chromated surface provides an excellent preparation for painting or further fabrication.

• Agricultural Building: Excellently suited for barns, silos, and storage facilities. The combination of strength and corrosion resistance offers reliable protection for equipment and livestock against the elements.

• Automotive Parts: Used in the production of various automotive components that require a strong, rust-resistant substrate, contributing to vehicle longevity and safety.

Packing and Shipping

Our Galvalume steel coils are securely packaged with waterproof wrapping and an inner moisture barrier, reinforced with protective steel sheets and hardened strapping for safe transit. They are shipped globally via sea, rail, or road freight in 20ft or 40ft HQ containers, loaded efficiently using cranes or forklifts.

FAQ

Q1: Where is Galvalume not recommended?
A: Avoid using Galvalume in direct contact with fresh concrete or mortar. These alkaline materials can accelerate corrosion. In such cases, hot-dip galvanized steel with a suitable paint system is preferable.

Q2: Does Galvalume develop discoloration?
A: Unlike galvanized steel, Galvalume may develop a dark patina over time when exposed to moisture during storage or transit. Proper handling and dry storage are essential to maintain its appearance.

Q3: How does Galvalume’s appearance differ from galvanized steel?
A: Galvalume has a matte gray-silver finish with a consistent spangle pattern, while galvanized steel tends to be brighter and more reflective. The difference stems from the aluminum content, which also enhances corrosion resistance.
