Applications of Galvanized Steel Coil Z275
1. Building enclosure system
High-end factory metal roof, modular clean room wall panels, airport terminal decorative panels.
2. Home appliance manufacturing
Refrigerator/washing machine housing, air conditioner outdoor unit cover, oven liner components.
3. Automobile industry
Chassis protection parts, cargo box baffles, new energy vehicle battery trays.
4. Agricultural facilities
Greenhouse frames, livestock breeding equipment, grain storage systems.
5. Photovoltaic new energy
Solar support, inverter box, power station fence system.
As industrial materials continue to upgrade, Z275 galvanized steel coil has become the preferred material in the fields of construction, automobile manufacturing, and home appliance production due to its excellent anti-corrosion performance and outstanding mechanical strength.
As a high-end galvanized product that meets international standards, this product adopts advanced continuous hot-dip galvanizing process, and the zinc layer weight is strictly controlled at 275g/m² (double-sided), which can maintain an effective anti-corrosion period of more than 10 years in harsh environments.
- Diversified surface treatment processes
| Surface type | Roughness (RA) | Applicable scenarios |
|---|---|---|
| Finished surface | 0.5-1.2μm | Home appliance panels, precision parts. |
| Zinc spangle surface | 1.5-2.5μm | Building exterior walls, industrial equipment. |
| Zinc spangle-free surface | ≤1.0μm | Automobile chassis, high-end decoration. |
- Excellent processing performance
Elongation ≥18% supports various processing methods such as stamping, bending, welding, etc., and the scrap rate is reduced by more than 30%.
