This FAQ guide helps architects, contractors, distributors and importers understand aluminum composite panels, specifications, applications and supplier selection.
Aluminum Composite Panel (ACP) is a lightweight flat panel consisting of two aluminum sheets bonded to a non-aluminum core material, usually a polyethylene (PE) core, fire-resistant mineral core, or other polymer-based core.
ACP combines the advantages of aluminum and composite materials, offering excellent flatness, durability, weather resistance, and easy fabrication. It is widely used for building facades, interior decoration, signage, advertising boards, and industrial applications.
Shanghai Alumetal produces various aluminum composite panels, including PE ACP, PVDF ACP, fire rated ACP, mirror ACP, brushed ACP, wooden grain ACP, and customized decorative panels.
ACP and ACM refer to the same type of product.
- ACP (Aluminum Composite Panel) is the commonly used term worldwide, especially in Asia, Europe, and the construction industry.
- ACM (Aluminum Composite Material) is more commonly used in North America.
Both describe a composite panel made of two aluminum skins with a core material between them.
Different markets may use different names, but the product structure and applications are essentially the same.
Aluminum composite panels are widely used in:
Exterior Applications
- Building facade cladding
- Curtain wall decoration
- Commercial building exteriors
- Shopping malls and office buildings
- Residential exterior decoration
Interior Applications
- Wall decoration
- Ceiling systems
- Column covering
- Partition decoration
- Exhibition displays
Advertising Applications
- Sign boards
- Digital printing boards
- Outdoor advertising panels
- Display stands
Industrial Applications
- Transportation interiors
- Furniture decoration
- Machine covers
ACP is popular because it provides a modern appearance with lightweight installation and excellent processing performance.
The main difference is the coating performance and application environment.
| Feature | PE ACP | PVDF ACP |
|---|---|---|
| Coating | Polyester coating | PVDF fluorocarbon coating |
| Durability | Good | Excellent |
| Weather resistance | Suitable for indoor and normal outdoor use | Suitable for long-term outdoor use |
| UV resistance | Medium | High |
| Color retention | Good | Better |
| Application | Signage, interior, short-term exterior | Building facade, curtain wall |
PE Aluminum Composite Panel
PE ACP is an economical choice for:
- Advertising boards
- Interior decoration
- Retail displays
- Short-term exterior projects
PVDF Aluminum Composite Panel
PVDF ACP is recommended for:
- High-rise buildings
- Commercial facades
- Long-term outdoor projects
- Areas with strong sunlight or harsh weather conditions
For exterior facade applications, PVDF aluminum composite panels are usually recommended because they provide:
- Superior weather resistance
- Better UV protection
- Long-lasting color stability
- Excellent coating adhesion
- Resistance to temperature changes
For projects requiring higher fire safety standards, fire rated aluminum composite panels, such as B1 or A2 grade panels, are also recommended.
The suitable panel depends on:
- Building height
- Local fire regulations
- Climate conditions
- Project requirements
- Design requirements
The suitable ACP thickness depends on the application.
Common ACP Thickness:
3mm ACP
- Indoor decoration
- Advertising boards
- Signage applications
4mm ACP
- Most common thickness for exterior facade
- Commercial buildings
- Curtain wall decoration
5mm-6mm ACP
- Large-scale projects
- Higher strength requirements
- Special architectural applications
Other factors to consider:
- Aluminum skin thickness
- Core material
- Installation method
- Wind load requirements
For most building facade projects, 4mm ACP with appropriate aluminum thickness is commonly selected.
Fire rated aluminum composite panel is an ACP designed with a fire-resistant mineral core instead of a standard polyethylene core.
It provides improved:
- Fire resistance
- Flame retardancy
- Safety performance
Common fire rated ACP types include:
B1 Fire Rated ACP
- Flame retardant performance
- Suitable for many commercial buildings
A2 Fire Rated ACP
- Non-combustible or highly fire-resistant
- Used for projects with strict fire safety requirements
Fire rated ACP is commonly used in:
- High-rise buildings
- Airports
- Hospitals
- Public buildings
- Large commercial projects
When selecting an ACP supplier, buyers should evaluate:
1. Manufacturing Capability
Check:
- Production lines
- Annual capacity
- Factory experience
2. Product Quality Control
A reliable manufacturer should provide:
- Quality inspection process
- Coating tests
- Thickness inspection
- Product certificates
3. Export Experience
Choose suppliers with:
