Aluzinc steel coil is a premium coated steel product that offers significant advantages over traditional galvanized steel. Its superior corrosion resistance, excellent heat reflectivity, enhanced durability, and aesthetic appeal make it a preferred choice for a wide range of applications, including construction, roofing, siding, and industrial uses. The combination of aluminium and zinc in the coating ensures long-lasting performance, making Aluzinc steel coils a valuable material for demanding environments.
Composition:
- Aluminum (55%): Provides exceptional corrosion resistance by forming a protective layer of aluminum oxide.
- Zinc (43.4%): Offers sacrificial protection, similar to traditional galvanized steel, protecting the steel substrate by corroding preferentially.
- Silicon (1.6%): Enhances adhesion of the coating to the steel and helps maintain the integrity of the alloy layer during fabrication.
2. G550 high-strength Aluzinc steel advantages
G550 high-strength Aluzinc steel strip, also known as Galvalume, is a popular material in the Australian market due to its exceptional mechanical properties and durability. This steel grade is characterised by a high tensile strength of 550 MPa, combined with the superior corrosion resistance provided by its aluminium-zinc alloy coating. This makes G550 an ideal choice for demanding applications across various industries.

Proper storage of Aluzinc steel coils during the rainy season is essential to prevent corrosion and maintain the quality of the material. Here are the guidelines and precautions for storing Aluzinc steel coils during wet weather:
Storage Guidelines
1. Indoor Storage:
- Warehouse Environment: Store the coils in a dry, well-ventilated warehouse to protect them from rain and high humidity.
- Elevation: Place the coils on elevated platforms or pallets to keep them off the ground and prevent contact with water.
- Temperature and Humidity Control: Maintain a stable temperature and humidity level inside the warehouse to prevent condensation on the coils.
2. Outdoor Storage:
- Covering: If indoor storage is not possible, cover the coils with waterproof tarpaulins or plastic sheets. Ensure that the covers are tightly secured to prevent water ingress.
- Proper Ventilation: Leave some space for air circulation under the covers to avoid moisture buildup and condensation.
- Inclination: Store the coils at a slight incline to facilitate water runoff and prevent pooling on the surface.
3. Packing:
- Sealed Packaging: Use moisture-resistant packaging materials to wrap the coils tightly. Consider vacuum-sealing or using desiccants inside the packaging to absorb any residual moisture.
- Edge Protection: Apply edge protectors to the coils to prevent damage during handling and storage.
