The mainstream aluminum coil materials include 1060 pure aluminum coil, 3003 rust-proof aluminum coil, 5052 aluminum-magnesium aluminum coil, and 5754 high-magnesium aluminum coil, with a small amount of 6061 and 6063 alloy aluminum coil. 1060 has high purity and a high cost-performance ratio; 3003 has stronger rust resistance; 5052 and 5754 are salt spray resistant and have higher strength, suitable for harsh environments.

Main Applications: Widely used in pipe insulation cladding, corrugated roofing sheets for factories, exterior wall decoration, and ceiling curtain walls; it can also be cut into aluminum sheets or slits into narrow strips; it is also used in automotive stamping parts, lamp housings, cold storage insulation, photovoltaic substrates, chassis sheet metal, and color-coated aluminum coil substrates.

What are the advantages of aluminum coils?

1. Rust and Corrosion Resistance: The aluminum surface has a dense oxide film, making it difficult to rust and oxidize. It is resistant to moisture and atmospheric corrosion, much more durable than sheet metal and galvanized sheets, and will not deteriorate even after long-term outdoor use.

2. Lightweight and Portable: Its low density makes handling and construction easier, reducing the overall load on building roofs and exterior walls.

3. Excellent Processing Performance: Good ductility and toughness allow for easy leveling, slitting, bending, tile making, and stamping, enabling the fabrication of various shapes to meet diverse project needs.

4. High Material Utilization: Supplied in whole rolls, it can be cut to size as needed, resulting in virtually no waste. Compared to sheet aluminum, it saves materials and reduces costs.

5. Long Weather Resistance and Lifespan: UV resistant, anti-aging, and resistant to deformation and fading. Ordinary aluminum coils can be used outdoors for over 15 years, while fluorocarbon coated aluminum coils can last 20-30 years.

6. Thermal Insulation and Energy Saving: Its highly reflective surface reflects solar radiation heat, reducing indoor temperatures in factories and buildings during summer, providing natural thermal insulation and cooling.

7. Beautiful Appearance: Available in various finishes including natural color, brushed, matte, and multi-color coatings, offering a rich variety of colors and styles, strong decorative appeal, and a unified and clean aesthetic.

8. Maintenance-free and cost-effective: No rust removal or painting is required after installation. One-time installation ensures long-term use, resulting in significantly lower overall operating costs compared to ordinary steel.

9. Environmentally friendly and recyclable: Aluminum is 100% recyclable and regenerable, producing no pollution and making it a green building material.

10. Flexible specifications: Thickness and width can be customized. Sufficient stock is available for both small and large batches, with fast delivery.
