What is Aluminum Composite Panel

Aluminum Composite Panel (ACP) is a lightweight, durable, and versatile building panel made by bonding two thin layers of aluminum to a non-aluminum core, typically polyethylene or fire-resistant mineral. ACP offer excellent weather resistance, thermal insulation, and a sleek modern appearance, making them ideal for exterior cladding, signage, and interior applications. Widely used in commercial and residential construction, ACP is available in a variety of colors, finishes, and textures, including metallic and wood grain. It is easy to fabricate, install, and maintain, providing a cost-effective solution for architectural design.

Features

🔹 Lightweight: Easy to transport and install due to its low density

🔹 High Strength and Rigidity: Despite being lightweight, ACM panels have excellent structural stability.

🔹 Weather Resistance: Resists UV rays, moisture, corrosion, and temperature extremes, making it ideal for outdoor use.

🔹 Flat and Smooth Surface: Provides a clean, modern look—perfect for cladding and signage.

🔹 Variety of Finishes: Available in metallic, solid colors, brushed aluminum, wood grain, stone, and custom finishes.

🔹 Excellent Workability: Easy to cut, bend, fold, drill, and fabricate using standard tools

🔹 Fire Resistance (FR Grade): Fire-rated versions use a mineral-filled core to comply with building codes and safety standards.

🔹 Thermal and Sound Insulation: Offers moderate insulation properties due to its core material.

🔹 Low Maintenance: Surfaces are easy to clean and resistant to dirt and staining.

🔹 Durability and Long Lifespan: Retains appearance and performance for years under various environmental conditions.

🔹 Eco-Friendly Options: Many ACM panels are recyclable and manufactured using sustainable processes.

🔹 Cost-Effective: Provides a high-end look and performance at a lower cost compared to solid metal sheets or natural materials.

🔹 Color Consistency: Uniform coating quality ensures visual consistency across large projects.

Applications

Aluminum Composite Panel (ACP) is highly versatile and widely used across multiple industries. Here’s a categorized list of its key applications:

🔹Building Facades & Cladding: Used for modern exterior walls, curtain walls, and rainscreen systems

🔹Interior Wall Panels: Decorative surfaces in lobbies, offices, and retail spaces.

🔹Outdoor Signboards & Billboards: UV-resistant and color-stable, ideal for long-term exposure.

🔹Retail Signage: Attractive surface for branding in shops and malls.

Cladding

Ulike Corporation offers high-performance Aluminum Composite Panel (ACP) panels specifically designed for exterior wall cladding. Manufactured with advanced coating technology, our ACP provide outstanding durability, weather resistance, and aesthetic appeal. Each panel features two aluminum cover sheets bonded to a non-combustible mineral-filled core, ensuring strength and fire resistance. The surface is finished with premium coatings through a continuous roller coating and baking process, delivering long-lasting performance even in harsh environmental conditions. Ideal for commercial, residential, and high-rise building facades, Ulike’s ACP cladding solutions are engineered to maintain their appearance and protection for up to 15–20 years.

🔹 PVDF (Kynar 500® Certified)

Made with fluorocarbon resin, PVDF coating is known for its superior weather resistance and long-term durability. Applied in multiple layers and baked at high temperatures (220–260℃), it offers excellent resistance to acid, alkali, UV rays, and environmental pollutants. Commonly used for exterior facades, PVDF-coated panels come with up to 15 years of warranty.

🔹 FEVE Coating

Developed in Japan, FEVE (Fluoroethylene Vinyl Ether) is a next-generation fluoropolymer coating offering similar durability to PVDF but with a broader gloss range (20%–80%). This makes it suitable for applications requiring vibrant colors and high-gloss finishes, such as modern architecture and outdoor signage. FEVE provides excellent adhesion, UV resistance, and color retention in extreme climates.
