Exterior Aluminium Composite Panel

Exterior Aluminium Composite Panel also know as “exterior acp sheet”. it is a commonly used building material, consisting of two layers of aluminum sheets and a core material of polyethylene (PE) or fire-resistant mineral core. The aluminum sheets are often treated for corrosion resistance to enhance their weatherability and durability. Exterior Aluminium Composite Panel is characterized by its lightweight, durability, ease of processing and installation, and good fire resistance.

Compared to interior Aluminium Composite Panel, there are some differences in performance and characteristics.

1. Exterior Aluminium Composite Panel is mainly used for exterior wall decoration, requiring high weatherability and durability to withstand various climatic conditions and external environments.
2. Interior Aluminium Composite Panel is primarily used for interior decoration, such as interior walls, ceilings, partitions, focusing on aesthetics and decorative effects.
3. Due to long-term exposure to outdoor environments, exterior Aluminium Composite Panel requires higher weatherability and corrosion resistance. Therefore, it often utilizes fluorocarbon (PVDF) coating to enhance weatherability and durability.
4. Interior Aluminium Composite Panel has lower weatherability requirements and can choose other coatings, such as polyester (PE) coating or ordinary spray coating.

In terms of thickness：

• 4mm thickness is more common for exterior wall decoration, providing better strength and wind pressure resistance compared to 3mm thickness.
• Interior Aluminium Composite Panel generally uses 3mm or 2mm thickness.

It is important to consider project requirements, budget, structure, and performance when selecting the appropriate thickness.
