Aluminium ACP sheet (Aluminum Composite Panel) is a popular building material consisting of two aluminum sheets bonded to a non-aluminum core. These lightweight, durable panels are widely used in modern construction for facades, signage, and interior applications.

What is Aluminium ACP Sheet?
Aluminium ACP Sheet (Aluminium Composite Panel) is a lightweight and strong building material made of two aluminum layers bonded to a polyethylene (PE) or fire-resistant (FR) core. It is known for its smooth surface, durability, and weather resistance.

ACP sheets are widely used for:
- Building façades and cladding
- Signboards and display panels
- Interior wall decoration
- Corporate branding and shopfronts
Sheet Thickness in mm
ACP sheets are available in several standard thicknesses. The thickness determines the rigidity, weight, and application type.
Below is a simple chart showing common ACP sheet thickness in millimeters (mm):
| ACP Type | Total Thickness (mm) | Aluminum Skin (mm) | Core Material | Application |
|---|---|---|---|---|
| Standard Panel | 3 mm | 0.12 – 0.18 mm | PE Core | Indoor signs, displays |
| Exterior Panel | 4 mm | 0.25 – 0.30 mm | PE / FR Core | Building cladding |
| Heavy-Duty Panel | 5 mm | 0.40 mm | FR Core | Outdoor walls, facades |
| Industrial Panel | 6 mm | 0.50 mm | FR Core | High-rise, industrial use |
Tip: 4mm ACP sheet is the most commonly used for exterior wall cladding.
ACP Sheet Thickness Chart
This chart helps visualize ACP sheet thickness and approximate weight per square meter:
| Thickness (mm) | Weight (kg/m²) | Recommended Use |
|---|---|---|
| 3 mm | 3.5 – 4.0 | Indoor decoration, display boards |
| 4 mm | 5.0 – 5.5 | Exterior wall cladding |
| 5 mm | 6.0 – 6.5 | Structural facades |
| 6 mm | 7.0 – 7.5 | High-performance applications |
ACP Sheet Size and Price
ACP sheet prices vary depending on thickness, coating type (PVDF, PE), and surface finish (glossy, brushed, marble, mirror).
Here’s a reference table for standard sizes and approximate prices:
| Size (mm) | Size (ft) | Thickness (mm) | Finish Type | Approx. Price (USD/m²) |
|---|---|---|---|---|
| 1220 × 2440 | 4 × 8 ft | 3 mm | PE Coated | $6 – $9 |
| 1220 × 2440 | 4 × 8 ft | 4 mm | PVDF Coated | $9 – $12 |
| 1500 × 3050 | 5 × 10 ft | 4 mm | Brushed / Mirror | $10 – $14 |
| 1500 × 3050 | 5 × 10 ft | 5 mm | Marble / Wooden | $11 – $15 |
ACP Sheet Size in cm
ACP sheets come in standardized sizes for easy installation and cutting.
Here’s a chart for ACP sheet size in centimeters (cm):
| Size in cm | Equivalent Size in ft | Common Use |
|---|---|---|
| 122 × 244 | 4 × 8 ft | Signboards, interior panels |
| 150 × 305 | 5 × 10 ft | Exterior façades |
| 125 × 320 | 4.1 × 10.5 ft | Large wall panels |
| Custom size | As required | OEM applications |
ACP Sheet Thickness in Inches
For international projects, ACP thickness is often referred to in inches. Below is a quick conversion chart:
| Thickness (mm) | Thickness (inches) | Usage |
|---|---|---|
| 3 mm | 0.12 inch | Indoor applications |
| 4 mm | 0.16 inch | Outdoor cladding |
| 5 mm | 0.20 inch | Heavy-duty usage |
| 6 mm | 0.24 inch | Industrial and façade systems |
ACP Sheet Size in Feet
Most ACP sheets are available in 4×8 ft or 5×10 ft formats, which are easy to handle and install.
Below is a detailed ACP sheet size in feet comparison:
| Standard Size (ft) | Equivalent (mm) | Best for |
|---|---|---|
| 4 × 8 ft | 1220 × 2440 mm | Retail and indoor design |
| 4 × 10 ft | 1220 × 3050 mm | Outdoor signage |
