Industrial Aluminum Coil for Window & Door Fabrication Systems

Precision Substrates for High-Speed Roll Forming and Automated Cutting

For door and window manufacturers, material consistency is the foundation of production efficiency. Our aluminum coils are specifically engineered for the fabrication of window profiles, thermal break strips, roller shutters, and architectural flashings. We provide the mechanical precision required for automated CNC machining and the coating resilience needed for tight-radius roll forming.

## Engineering Excellence for Fabrication Lines

1. Zero-Defect Roll Forming

Our 3000 and 5000 series alloys are annealed to provide consistent yield strength. This ensures that when the coil passes through your roll-forming or bending machinery, the profiles remain dimensionally stable with zero spring-back and no microscopic cracking in the coating at the bend radii.

2. Industry-Leading Coating Adhesion

Using multi-stage chemical pre-treatment, we ensure the bond between the aluminum and the coating (PVDF/PE) can withstand high-speed sawing, punching, and milling.

• Edge-Retention: The paint film holds firm during sharp cutting, preventing the "edge-peel" that can lead to long-term corrosion at the joints.

3. Absolute Color Consistency ($\Delta E < 0.5$)

We understand that a single project may require hundreds of window units. Our automated coating lines guarantee batch-to-batch color uniformity, ensuring that frames, sashes, and sills manufactured at different times match perfectly under all lighting conditions.

## Regional Performance Specifications

• Middle East (High-Heat/UV): We utilize Kynar 500® PVDF coatings. These are chemically formulated to resist high-ambient heat and intense solar radiation, preventing the chalking and fading common in Gulf climates.

• North America (Structural & Marine): Compliant with AAMA 2604/2605 and ASTM B209. Our 5052-H32 coils provide the salt-spray resistance required for coastal glazing projects.

• Central Asia (Extreme Thermal Cycles): Our tension-leveled coils prevent buckling and "oil-canning" during the rapid expansion and contraction cycles typical of steppe climates.

## Technical Specifications

• Alloy Portfolio: 1050, 1100, 3003, 3105, 5005, 5052.

• Temper: H14, H16, H24, H26 (Optimized for CNC and roll-forming).

• Thickness: 0.15mm – 3.0mm (Tolerance within $\pm 0.01\text{mm}$).

• Widths: Precision slitting available from 20mm up to 1600mm for specific profile widths.

• Surface Finishes: PE, PVDF, Wood-Grain, Stucco Embossed, or High-Gloss White/Black.

## Quality Control for Manufacturers

• T-Bend Test: Guaranteed $1T$ bend performance without paint loss.

• Cross-Hatch Adhesion: Verified level 5B adhesion for punching and milling operations.

• Surface Protection: High-tack UV-resistant PVC film protects the decorative surface throughout your entire fabrication, assembly, and transport process.

## Global Logistics & Packaging

We understand the "Just-in-Time" requirements of modern factories.

• Sea-Worthy Packaging: Reinforced edge protection and triple-layer moisture barriers to prevent "white rust" during transit.

• Documentation: Every shipment includes a Mill Test Certificate (MTC) and detailed coating thickness/gloss reports for your QC archives.
