Galvalume Steel Coil AZ50
In-depth analysis of AZ50 galvanized steel coil - parameters and performance
1. Naming code: AZ50
AZ = Aluminum-Zinc
50 = Total weight of double-sided coating 50g/㎡ (golden thickness in the industry, balancing cost and protection)
2. Key performance parameter table
| Index | AZ50 galvalume steel coil | Ordinary galvanized steel (GI) | Improvement |
|---|---|---|---|
| Coating composition | 55%Al-43.4%Zn-1.6%Si | 100%Zinc | Advantages of alloy structure |
| Maximum operating temperature (℃) | 315 (continuous)/480 (peak) | 230 (blackening and peeling) | Heat resistance breakthrough |
| Coating adhesion | Top grade (T-bend test 0T) | Easy to fall off | Processing stability doubled |
Applications - How does AZ50 create value?
🏗️ Construction field
Roof/wall system: resist acid rain and coastal high salt fog (case: a seaside hotel has been used for 15 years without rust)
Steel structure maintenance: replace stainless steel, reduce costs by 50%
🔧 Industrial manufacturing
Photovoltaic bracket: 25-year lifespan matches the power station cycle
Granary/livestock farm: anti-ammonia corrosion, humidity tolerance 90%
🏭 Home appliances and automobiles
| Industry | Typical components | AZ50 solution |
|---|---|---|
| Home appliances | Air conditioner outdoor unit/water heater tank | Weather resistance increased by 3 times, warranty extended |
| Automobile | Exhaust pipe guard/fuel tank housing | Weight reduction of 30% + anti-gravel impact |
| Electromechanical | Electrical cabinet/transformer housing | Electromagnetic shielding + maintenance-free |
