What Is a 4mm Aluminium Composite Panel

Structure and Materials

When you look at 4mm aluminium composite panel, you see a smart design. These acp panels have two thin aluminum sheets on the outside. The core sits between them and uses a solid thermoplastic with inorganic fillers. This core gives the panel strength and helps with fire safety. Most acp panels use aluminum alloys like AA3000 or AA5000. Each aluminum sheet is about 0.50 mm thick. The total thickness of the panel is 4 mm, which is the industry standard for many types of acp sheets.

You can find different types of acp sheets with various finishes. Some have PVDF coatings, powder coatings, or even brushed aluminum surfaces. These coatings protect the acp panels from weather and keep them looking new. The panels come in standard sizes, such as 1220 x 2440 mm, but you can also get larger sizes for special projects. The structure of these aluminum composite panels makes them strong, light, and easy to use in many places.
