3. 3. CNC Machining & Fabrication: The rolled sheets or extruded profiles undergo precise CNC machining. This includes cutting, punching, routing, bending, and welding to form specific panel dimensions, edge profiles, and attachment points. Tolerances are typically maintained within +/- 0.5mm to ensure seamless integration.
4. 4. Surface Treatment: This critical stage enhances aesthetics and durability. Common treatments include:
   • Anodizing: An electrochemical process that thickens the natural oxide layer, improving corrosion and abrasion resistance. Anodized finishes can range from clear to various metallic colors.
   • Powder Coating: Electrostatic application of a dry powder, followed by heat curing. This creates a hard finish that is tougher than conventional paint and offers a wide array of colors and textures. Common standards include AAMA 2603, AAMA 2604, and AAMA 2605 (for superior weather resistance).
   • PVDF (Polyvinylidene Fluoride) Coating: A high-performance liquid coating known for its excellent color retention, chalk resistance, and UV stability, making it ideal for exterior applications. Typical thickness ranges from 25-35 microns for two-coat systems and 35-45 microns for three-coat systems.
5. 5. Quality Control & Testing: Throughout the manufacturing process, strict quality control measures are implemented. This includes dimensional checks, coating adhesion tests (e.g., cross-hatch test), color uniformity, and mechanical property verification. Finished products are tested against international standards such as ISO 9001 for quality management, ASTM (American Society for Testing and Materials) for material properties and performance, and EN (European Standards) for construction products.
6. 6. Assembly & Packaging: Components are assembled, if required, and meticulously packaged to prevent damage during transit to the project site.

The typical service life of high-quality aluminium cladding, when properly installed and maintained, can exceed 30-50 years, often matching or surpassing the lifespan of the building itself.
