Aluminum vs Composite Panels for Modular Home Exteriors

1. Core Material Characteristics

1.1 Aluminum Panels

• Composition: Solid aviation-grade aluminum alloy (3-5mm thick), with fluorocarbon coating on the surface.
• Key Traits: High strength, corrosion resistance, and a service life of over 20 years.
• Weight: Lightweight (2.7 kg/㎡) yet rigid, ideal for modular structure load-bearing.

1.2 Composite Panels (ACP)

• Composition: Two thin aluminum sheets bonded to a polyethylene (PE) core (3-4mm thick total).
• Key Traits: Cost-effective, versatile, and easy to process into various colors/designs.
• Weight: Ultra-light (1.5 kg/㎡), reducing transportation and installation effort.

3. Cost & Installation

3.1 Cost

• Aluminum Panels: Higher upfront cost (≈$80-120/㎡) due to premium material and processing.
• Composite Panels: Lower initial cost (≈$30-60/㎡), making it a budget-friendly option.

3.2 Installation

• Aluminum Panels: Requires precise cutting and sealing to avoid water leakage; factory prefabrication is recommended.
• Composite Panels: Easy to cut, bend, and splice; on-site installation is faster and simpler.

4. Scenario Suitability

4.1 Best for Aluminum Panels

• High-end projects: Luxury homestays, star houses, and commercial pods in scenic spots.
• Harsh environments: Coastal areas (anti-salt spray), mountainous regions (anti-corrosion), and desert areas (UV resistance).
• Long-term use: Projects requiring minimal maintenance and a 20+ year service life.

4.2 Best for Composite Panels

• Mid-range projects: Budget homestays, temporary offices, and construction site pods.
• Mild climates: Inland regions with stable weather (no extreme heat/cold/salt).
• Custom designs: Projects needing wood grain, marble, or gradient finish exteriors.

5. Hongyuan Yunshe’s Recommendation

• For high-end 文旅 (cultural tourism) projects: Choose aluminum panels for durability and premium aesthetics—they align with luxury glamping and resort branding.
• For cost-sensitive temporary projects: Opt for composite panels to balance performance and budget.
• Hybrid option: Use aluminum panels for high-wear areas (e.g., base, window frames) and composite panels for the main facade to save costs.
