ACP Sheet 3mm – Detailed Description

ACP (Aluminium Composite Panel) 3mm is a lightweight, durable, and versatile cladding material widely used in architectural, interior, and signage applications. It consists of two thin aluminium sheets bonded to a non-aluminium core, forming a rigid yet flexible panel.

1. Composition & Structure

• Total Thickness: 3 mm

• Aluminium Skin Thickness: Typically 0.12 mm to 0.25 mm per side

• Core Material:

  • Low-density polyethylene (LDPE) core (standard)

  • Fire-retardant (FR) mineral-filled core (optional)

• Surface Coating:

  • PVDF coating (for exterior use – high weather resistance)

  • PE coating (for interior use – cost-effective)

2. Standard Sizes

• Common Sheet Size:

  • 1220 mm × 2440 mm (4 ft × 8 ft)

• Other Available Sizes:

  • 1250 × 2500 mm

  • 1500 × 3050 mm

  • Custom sizes available depending on manufacturer

3. Weight

• Approx. 3.5 – 4.5 kg per m², depending on aluminium thickness and core type

• Lightweight compared to solid aluminium sheets

4. Surface Finish Options

• Solid colors (matte & glossy)

• Metallic finish

• Wooden texture

• Marble & stone finish

• Brushed aluminium

• Mirror finish

• Sparkle / high-gloss finish

5. Key Properties

• ✔ Excellent flatness and smooth surface

• ✔ High strength-to-weight ratio

• ✔ Corrosion and moisture resistant

• ✔ UV and weather resistant (PVDF coated)

• ✔ Easy to cut, bend, fold, and fabricate

• ✔ Good sound and thermal insulation

• ✔ Low maintenance and easy to clean

6. Applications

Exterior Applications

• Building façade cladding

• Column covers

• Canopies

• Shop fronts

• Signboards (with PVDF coating)

Interior Applications

• Wall paneling

• False ceilings

• Partitions

• Interior décor elements

• Modular furniture panels

Advertising & Signage

• Hoardings

• LED signboards

• Display panels

• Digital printing base

7. Advantages

• Modern and premium appearance

• Long service life (15–20 years for exterior PVDF)

• Cost-effective compared to solid aluminium

• Quick installation

• Wide range of colors and textures

8. Limitations

• 3mm thickness is not structural

• Fire performance depends on core type

• Can dent under heavy impact

• Quality varies by manufacturer

Aluminium Composite Panel (ACP) – Detailed Description & Specifications 1. What is ACP Sheet?

An Aluminium Composite Panel (ACP) is a flat panel consisting of:

• Two thin aluminium sheets (outer layers)

• Non-aluminium core (middle layer – polyethylene or fire-retardant mineral core)

ACP sheets are widely used in:

• Exterior building façades

• Interior wall cladding

• Signage boards

• False ceilings

• Partitions

• Modular furniture

They are lightweight, durable, weather-resistant, and easy to fabricate.

2. Structure of ACP Sheet

Typical Layer Composition (Top to Bottom):

1. Protective Film (temporary protection during installation)

2. PVDF or Polyester Coating

3. Aluminium Skin (0.12mm – 0.50mm)

4. Adhesive Layer

5. Core Material (LDPE / FR Core)

6. Adhesive Layer

7. Back Aluminium Skin

8. Service Coating (Primer or Polyester)

3. Standard Technical Specifications A. Standard Dimensions

Most common: 4mm thick with 0.21mm or 0.30mm aluminium skin

B. Core Material Types C. Coating Types

PVDF coating provides:

• UV resistance

• Weather resistance

• Color retention

• Anti-corrosion protection

4. Physical Properties 5. Fire Rating (Important for Exterior Use)

For high-rise buildings, FR or A2 grade is recommended.

6. Advantages of ACP Sheets

✔ Lightweight
✔ Easy to cut, bend & route
✔ Excellent surface finish
✔ Available in metallic, wooden, marble, solid & mirror finishes
✔ Low maintenance
✔ High weather resistance
✔ Cost-effective

7. Applications

• Commercial building façades

• Petrol pump canopies

• Corporate sign boards

• Airports & malls

• Hospitals

• Showrooms

• Interior wall decoration

• Kitchen cabinets
