When choosing metal roofing, many people focus only on thickness and design, but overlook one critical factor: the protective coating. This layer plays a major role in determining corrosion resistance, durability, and long-term performance.
One of the most advanced technologies used today is AZ (Aluminium-Zinc) coating, which is applied in EURODEK by EURO ROOF to ensure superior protection.
What is AZ Coating?
AZ coating is a combination of:
- ~55% Aluminium
- ~43.5% Zinc
- ~1.5% Silicon
This composition provides dual protection:
- Aluminium → protects against heat and oxidation
- Zinc → protects against corrosion
Main Functions of AZ Coating
1. Anti-Corrosion Protection
Protects the steel from rust caused by moisture and air.
2. Weather Resistance
Suitable for extreme conditions:
- Heavy rain
- Strong sunlight
- High humidity
3. Longer Lifespan
AZ-coated roofing lasts significantly longer than regular materials.
4. Lower Maintenance Cost
Less damage means lower repair and maintenance expenses.
AZ100 vs AZ150
AZ100
- Thinner coating
- Suitable for standard use
- More affordable
AZ150
- Thicker coating
- Better protection
- Longer lifespan
➡️ Conclusion: AZ150 is ideal for industrial and harsh environments.
AZ vs Standard Material Comparison
| Factor | AZ Coating | Standard Material |
|---|---|---|
| Anti Corrosion | High | Low |
| Lifespan | Longer | Shorter |
| Maintenance | Low | Higher |
