What is an aluminium composite panel?

Aluminum Composite Panel (ACP) is a material made of two aluminum sheets and a plastic core layer (polyethylene). It has numerous advantages, including lightweight, high strength, fire resistance, waterproofing, sound insulation, insulation, and corrosion resistance. acp structure

Applications of Aluminum Composite Panel

ACP has a wide range of applications, mainly used in building facades, billboards, interior decoration, airport and subway stations, etc.

Exterior – façade, canopy, overhang, soffit and more.
Interior – wall covering, false ceiling, cupboards, wardrobes, modular kitchens, table tops, column covers and more.
Corporate Identity Design – Signage, kiosks, totems, POPs, fascia, etc.
For cladding all types of facades.
Balcony cladding.
Canopies, tunnels, subway interiors, telephone booths, column covers or renovations

Types of Aluminum Composite Panel

Regular Aluminum Composite Panel:

The regular aluminum composite panel consists of two layers of aluminum sheets bonded with a polyethylene (PE) core. The surface of the aluminum sheets is treated with paint coating (PVDF/PE).

It is available in solid colors, metallic colors, and can be customized to any desired color.

The standard size is 1220x2440mm, but it can be customized up to a maximum length of 6 meters and a maximum width of 1575mm.

Wooden Aluminum Composite Panel:

The wooden aluminum composite panel has the same structure and dimensions as the regular aluminum composite panel. The difference is that the surface aluminum sheet has a wood grain finish. It is commonly used for interior wall decoration and occasionally for outdoor applications.

Marble Aluminum Composite Panel:

The marble aluminum composite panel has the same structure and size as the standard aluminum composite panel. The difference lies in the surface aluminum sheet, which features a stone texture. It is mainly used for exterior wall decoration but can also be used indoors.

Brushed Aluminum Composite Panel:

The brushed aluminum composite panel has a structure similar to the standard aluminum composite panel, with two layers of aluminum sheets bonded with a polyethylene core. The surface aluminum sheet undergoes a brushed effect treatment without a paint coating.

This type is less commonly used, so the options for special sizes may be limited. It is advisable to consult with the supplier for specific requirements.

Fireproof Aluminum Composite Panel:

Fireproof aluminum composite panel is a building material with a structure similar to regular aluminum composite panels, consisting of two aluminum sheets bonded to a non-aluminum core. The difference lies in the core material, where conventional aluminum composite panels use polyethylene (PE), while fire-resistant aluminum composite panels use flame-retardant mineral material.

Fire-resistant aluminum composite panels can be classified into B2, B1, and A2 levels based on their fire resistance performance.

B2 fireproof panels have high flame propagation and smoke development, while B1 panels have limited flame propagation and smoke development.

A2-level fireproof aluminum composite panels have the best fire resistance performance, with minimal smoke and no combustible droplets.

The main difference between these levels lies in their ability to resist fire, smoke, and toxic gases, which is crucial in determining their use in different buildings and environments.

Thickness of Aluminum Composite Panel

The thickness of ACP is usually 2mm, 3mm, 4mm, 5mm, 6mm, etc. The specific selection should be based on the use environment, load requirements, installation method, and other factors.

Installation of Aluminum Composite Panels (ACP)

Fix the ACP panels to the installation corner connectors (made of aluminum or stainless steel) using rivets.
Before connecting the ACP panels to the installation framework (such as steel plates), ensure that there is at least a 25u thick insulation and galvanized material layer.
All joints should have a specified width. The difference in width between adjacent or vertical joints should not exceed 2.5 millimeters.
Adhere one side of the corner material to the curved edge of the ACP panel using high-strength structural adhesive.
Connect the middle of the corners with rivets to create prefabricated panels for wall installation.
The design of the support brackets should allow for three-dimensional adjustment and precise positioning of the wall components.
Connect the prefabricated ACP panels one by one by adjusting them to the same level and sealing them with rivets and self-tapping screws.

Price of Aluminum Composite Panel

The price of ACP is influenced by many factors, including thickness, surface treatment method, brand, supply and demand relationship, etc. Generally, the price of ACP on the market ranges from 20 yuan to 150 yuan per square meter.

Conclusion

Aluminum composite panel has become a popular building material due to its various advantages and wide range of applications. When selecting ACP, it is essential to consider the specific needs and installation requirements.
