AZ100 Aluzinc IBR Trapezoidal Steel Tiles Galvalume Corrugated
Metal Sheets
1. Description
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.
