ACP Panel Thickness and Type Options
| Panel Type | Total Thickness | Aluminum Skin | Core Type | Application |
|---|---|---|---|---|
| Standard ACP | 4mm | 0.21mm | LDPE | Signboards |
| Fire Retardant | 4mm / 5mm | 0.3mm | FR Core | Facade Cladding |
| Mirror ACP | 3mm / 4mm | 0.21mm | LDPE | Interior Design |

Classification of ACP Panels
ACP panels are categorized based on core material, fire rating, and surface finish:
| Type | Core Material | Fire Rating | Best For |
|---|---|---|---|
| Standard ACP | Polyethylene (PE) | Class B | Commercial buildings, signage |
| Fire-Retardant ACP | Mineral-filled | Class A2 | High-rise buildings, public spaces |
| Anti-Bacterial ACP | PE with additives | Class B | Hospitals, clean rooms |
| PVDF ACP | PE core with PVDF coating | Class B | Premium facades, long-term color retention |
Thickness Options
ACP thickness affects rigidity, weight, and application suitability:
| Total Thickness (mm) | Aluminium Skin (mm) | Core (mm) | Weight (kg/m²) | Recommended Use |
|---|---|---|---|---|
| 3mm | 0.25 + 0.25 | 2.5 | 3.5-4.5 | Indoor decoration, signage |
| 4mm | 0.30 + 0.30 | 3.4 | 5.5-6.5 | Retail facades, partitions |
| 6mm | 0.50 + 0.50 | 5.0 | 7.5-8.5 | Exterior cladding, canopies |
Aluminium Alloy Specifications
The outer aluminium skins typically use:
| Alloy | Properties | Best For |
|---|---|---|
| 3003 | Good formability, corrosion resistant | Standard facades |
| 5005 | Higher strength, excellent anodizing quality | Premium projects |
| 5052 | Superior marine-grade resistance | Coastal buildings |
Packaging Standards
To ensure damage-free delivery:
-
Protective film coating on both sides
-
Foam edge protectors on all corners
-

What is an Aluminium Composite Panel?
An Aluminium Composite Panel (ACP) is a flat panel made of two thin aluminum sheets bonded to a non-aluminum core. These panels are used widely for modern architectural cladding, signage, partitions, and display panels due to their durability, lightweight, and sleek appearance.
Features and Advantages of ACP
-
Lightweight yet rigid and durable
-
Weather and UV resistant (especially PVDF coated)
-
Excellent flatness and smooth surface
-
Easy to cut, shape, and install
-
Fire-retardant options available
-
Cost-effective for large surface areas
-
Wide range of colors and surface finishes
Applications of Aluminium Composite Panels
ACP sheets are used in various industries:
-
Building Façade Cladding (high-rise and low-rise buildings)
-
Ceilings and Partitions
-
Retail Interior Decorations
-
Exhibition Stands and Display Units
-
Vehicle Body Panels and Advertisements
-
Signboards, Billboards, and Hoardings
-
Kitchen Cabinets and False Ceilings
Surface Finishes Available
-
PE (Polyester) Coated – indoor use
-
PVDF (Polyvinylidene Fluoride) – outdoor and weatherproof
-
Brushed – metallic look
-
Mirror – glossy reflective
-
Wooden & Marble Patterns – decorative
Technical Specifications
| Parameter | Standard ACP | Fire-Retardant ACP |
|---|---|---|
| Tensile Strength | 80-100 MPa | 70-90 MPa |
| Peel Strength | ≥4 N/mm | ≥3.5 N/mm |
| Temperature Resistance | -50°C to +80°C | -50°C to +80°C |
| Color Retention | 10-15 years | 10-15 years |
Installation Benefits
-
50% lighter than solid aluminium panels
-
30% faster installation than traditional cladding
-
Easy cutting & forming with standard tools
-
Low maintenance – just annual cleaning
