Why Choose Color-Coated Aluminum Coils for Building Exteriors?

Aug. 11, 2025

Recommended Specifications for Exterior Applications

1. Thickness

  • Standard Use: 0.6–1.0 mm (ideal for most facades)

  • High-Strength/Harsh Environments: 1.0–1.5 mm (better wind resistance & durability)


2. Width

  • Common options: 1000 mm & 1200 mm

  • Custom widths available for specialized projects

3. Material Grades

MaterialPropertiesBest For
A1100 (Pure Aluminum)Good corrosion resistance, cost-effectiveBudget-friendly projects with moderate durability needs
A3003 (Aluminum-Manganese Alloy)Higher strength, excellent rust resistanceStandard exterior facades
A3004 (Aluminum-Magnesium-Manganese Alloy)Superior strength, long-term durabilityHigh-rise buildings & extreme weather conditions

4. Coating Types & Thickness

  • PVDF (Fluorocarbon) Coating (≥25 microns)

    • Best for extreme UV, acid rain, and coastal areas

    • 20+ years of fade & peel resistance

  • Polyester (PE) Coating (≥18 microns)

    • Cost-effective with 10–15 years of performance

    • Suitable for moderate climates

Key Features of Color-Coated Aluminum Coils

✅ Aesthetic Flexibility

  • Available in multiple colors & textures (wood, stone, metallic finishes)

  • Enhances modern & traditional architectural designs

✅ Superior Weather Resistance

  • UV-resistant coatings prevent fading & discoloration

  • Withstands acid rain, salt spray, and pollution

✅ Lightweight & High Strength

  • Reduces structural load (ideal for high-rise buildings)

  • Resists wind pressure, impacts, and deformation

✅ Easy Installation & Fabrication

  • Can be cut, bent, and shaped for custom designs

  • Simplifies construction timelines

✅ Eco-Friendly & Energy Efficient

  • 100% recyclable & sustainable

  • Reflective coatings improve thermal insulation, lowering energy costs

✅ Fireproof & Low Maintenance

  • Non-combustible material (enhances building safety)

  • Smooth surface repels dirt—easy to clean with water

Best Applications for Color-Coated Aluminum Coils

✔ Commercial Buildings (offices, malls, airports)
✔ Residential Facades & Roofing
✔ Industrial Sheds & Warehouses
✔ HVAC & Insulation Systems

Conclusion

For long-lasting, visually appealing, and durable building exteriors, color-coated aluminum coils are an excellent choice. Opt for PVDF coatings in harsh climates and A3004 alloy for high-strength requirements. Their lightweight, low-maintenance, and eco-friendly properties make them a top material in modern construction.

OUR ADVANTAGES

Smoothness

There is no residual stress on the surface and no deformation after shearing

Weather resistance

The paint pattern made by roller coating and high temperature baking has high gloss, good color stability and little color difference change

Decorative

There is a fresh natural beauty, the pattern is casual and do, give customers a wide range of personality choices, can enrich the culture of the product, give people more beautiful enjoyment.

Environmental Protection

Resistant to salt, alkali and acid rain corrosion, will not corrode or produce toxic bacteria, does not release any toxic gases.

Mechanical

ACP after composite with plastic and adhesive. With the flexural and flexural strength required by the decorative plate, in the four seasons climate, the change of wind pressure, temperature, humidity and other factors will not cause bending, deformation,expansion and so on.
