1. Product Composition & Structure
- Coating Formula: 55% aluminum, 43.4% zinc, and 1.6% silicon . This ternary alloy forms a dense protective layer through high-temperature solidification (600°C), creating a robust barrier against environmental degradation.
- Base Material: Cold-rolled or hot-rolled steel substrate, ensuring excellent mechanical strength and formability .
- Surface Finish: Smooth, spangled appearance with optional treatments (e.g., chromate passivation, oiling) to enhance anti-fingerprint and storage performance .

2. Key Advantages
2.1 Exceptional Corrosion Resistance
- Outperforms traditional galvanized steel by 2–4 times in salt spray tests (e.g., 1,000 hours in 5% NaCl at 35°C with minimal corrosion) .
- Aluminum-rich coating provides self-healing properties, resisting oxidation, acid rain, and UV exposure .
2.2 Thermal & Aesthetic Performance
- Withstands temperatures up to 315°C, ideal for roofing and high-heat environments .
- Available in pre-painted variants (polyester, PVDF, or SMP coatings) for customizable colors and architectural aesthetics .
2.3 Eco-Friendly & Cost-Effective
- Recyclable material aligned with green building standards, reducing lifecycle environmental impact .
- Long service life (20–30 years) minimizes maintenance and replacement costs .
