Al-Zn Alloy Coated Steel (Aluzinc) is a high-performance corrosion-resistant steel product. It uses a molten Zn-Al-Mg alloy coating instead of pure zinc, applied in a continuous hot-dip galvanizing line. The coating structure is a zinc-based alloy rich in aluminum and magnesium, offering far superior corrosion and wear resistance than regular galvanized steel.
Key Advantages:
- Superior Corrosion Resistance: 2-6 times more salt spray resistant than regular galvanized steel, especially excelling in harsh environments like coastal areas and chemical plants.
- High Heat Resistance: Excellent thermal stability, with a long-term service temperature of up to 300℃, suitable for high-temperature equipment.
- Self-healing Cut Edge: Magnesium in the coating forms a dense protective film at cut edges to prevent corrosion, significantly extending service life.
- Compatibility with High Strength: Perfectly bonds with high-strength substrates to meet the demands of high-end structural components.
Typical Applications: Building facades, roofs, highway guardrails, shipping containers, automotive floor pans, outdoor electrical equipment, and metal roofing systems.
