Common mistakes in designing aluminum composite walls (Aluminum Cladding/Facade Panels)

Materials and Structure of Decorative Aluminium Panels

Decorative aluminium panels are made from high-quality aluminium alloy sheets with standard thicknesses of 1.5, 2.0, 2.5, or 3.0 mm (Series 3003, H24), with typical dimensions of 1220 × 2440 mm.    Each panel consists of surface panel + reinforcing ribs + corner brackets. The reinforcing ribs are fastened to the panel with welded bolts, making it strong and resistant to wind and vibration. If sound insulation or heat resistance is needed, additional insulation materials can be added inside.

Surface Coating of Aluminium Panels

The panel surface undergoes pretreatment (e.g., chromate) before being coated with fluorocarbon paint (PVDF coating), which offers high durability.

  • Can be coated with 2, 3, or 4 layers depending on requirements.

  • Resistant to acids, acid rain, salt spray, pollution, and UV radiation.

  • Color does not fade or peel and has a lifespan of 20–25 years. Factories typically use high-quality brands such as PPG, DNT, AKZO, NIPPON with a wide range of colors.

Key Features of Decorative Aluminium Panels

  • Lightweight yet strong, capable of withstanding wind and impact.

  • Corrosion and weather resistant, with PVDF coating maintaining long-lasting color.

  • Versatile in shaping, including flat, curved, or special forms.

  • Easy to maintain, dust and dirt are difficult to stick, and cleaning is simple.

  • Quick installation as panels are factory-prepared, requiring minimal on-site adjustments.

  • 100% recyclable, environmentally friendly.

Suitable Applications

Ideal for a variety of architectural applications such as exterior and interior walls, lobbies, columns, skywalks, pedestrian bridges, elevator frames, balconies, signage, and special ceiling designs.

Common Mistakes in Designing Aluminium Panels

1. Overemphasis on Uniqueness

Sometimes clients demand excessive differentiation, such as using highly textured patterns or combining glass with reflective materials. This can make the aluminium panels difficult to maintain, prone to dirt, and lose aesthetic appeal over time.

2. Improper Use of Lighting

Although aluminium panels can interact beautifully with lighting, using too many colored lights can make the facade appear cluttered, visually overwhelming, and lacking elegance.

3. Non-standard Supporting Structure (Aluminium Framework)

Some projects neglect the internal supporting structure, but the framework directly affects strength and wind resistance. Incorrect placement can result in warped or unstable panels.

4. Overlooking Maintenance

Even though aluminium panels have self-cleaning and durable properties, components like sealants have a shorter lifespan and require inspection and maintenance, such as sealing joints to prevent cracking due to expansion and contraction.

Conclusion: Choosing decorative aluminium panels requires careful consideration of design, structure, lighting, and maintenance. Avoiding these common mistakes ensures panels that are beautiful, durable, and long-lasting.
