Aluzinc Coil

Aluzinc Steel Coil, also known as Galvalume or Zincalume, is a cold-rolled carbon steel sheet coated with a corrosion-resistant alloy of 55% aluminum, 43.4% zinc, and 1.6% silicon through a continuous hot-dip process . This unique composition combines the physical protection and high durability of aluminum with the electrochemical (sacrificial) protection properties of zinc .

The result is a high-performance product characterized by a smooth, flat surface with a characteristic elegant spangled silver-white appearance. A thin, transparent layer of aluminum oxide on the surface preserves this attractive finish over time, eliminating the need for additional painting in many applications.

Product Features & Advantages

Superior Corrosion Resistance: 55%Al-Zn alloy coating forms a protective barrier, resisting salt spray, moisture, UV and chemicals—more durable than traditional galvanized coils, ideal for coastal and humid areas.

High Strength & Durability: High-tensile base steel combined with firm alloy coating ensures good load-bearing, anti-deformation and impact resistance, extending service life and reducing maintenance.

Excellent Processability: Easy to cut, bend, weld and stamp without damaging the coating, adapting to various construction and production requirements.

Cost-Effective: Balances high performance and reasonable pricing, eliminating extra anti-rust treatment costs for bulk applications.

Eco-Friendly: Non-toxic alloy coating meets international environmental standards, with good heat reflection to save energy.
