What Are Aluminium Composite Panels? A Complete Overview

If you’ve ever driven past a sleek corporate tower or a modern airport, you’ve seen aluminium composite panels (ACP). But what are aluminium composite panels exactly? They are sandwich panels consisting of two thin aluminium coils bonded to a non‑aluminium core. This simple yet ingenious structure gives architects the power to create lightweight, durable, and stunning facades. In India, ACP has become the material of choice for cladding, signage, and interiors.

How Are Aluminium Composite Panels Manufactured?

ACP manufacturing involves continuous coil coating of aluminium (0.2–0.5mm thick) with PVDF or polyester paint. The coated coils are then bonded to a polyethylene or fire‑rated mineral core using a high‑temperature lamination process. The panel is cooled, cut to standard sizes (8×4 ft), and protected with a peel‑off film.

Types of Aluminium Composite Panels

• Polyethylene (PE) Core ACP: Economical, suitable for low‑rise interiors and signage.
• Fire‑Retardant (FR) ACP: Mineral‑filled core, Class A2/B1, mandatory for high‑rise buildings in India.
• PVDF Coated ACP: Superior UV and weather resistance for exterior facades.
• Digital Print ACP: Customised graphics and branding possibilities.

Advantages of Aluminium Composite Panels

• Lightweight (reduces structural steel by 10–15%)
• Excellent flatness and rigidity
• Resistant to moisture, termites, and UV rays
• Wide colour palette with warranty up to 20 years
• Fast installation with simple tools
• Fully recyclable

Disadvantages & Limitations

• Not a structural material; only cladding
• Poorly manufactured ACP can delaminate in heat
• Fire hazard if non‑FR core is used incorrectly
• Shows scratches on high‑gloss finishes
