aluminium composite panel and solid aluminium panel's difference 

The main difference between aluminium composite panels and solid aluminium panels lies in their composition and structure.

Aluminium composite panels (ACP) consist of two layers of aluminium sheets sandwiching a core material, usually made of polyethylene or fire-retardant material. The layers are bonded together with a strong adhesive, creating a lightweight and rigid panel. ACPs are commonly used in exterior cladding, signage, and building facades due to their durability, low cost, and design flexibility.

On the other hand, solid aluminium panels are made of a single layer of aluminium, typically with a thickness of 2-3mm. They are heavier and more rigid than ACPs, but also more durable and resistant to impact and weathering. Solid aluminium panels are commonly used in high-end architectural applications, such as curtain walls, column covers, and soffits, where a premium aesthetic and long-term performance are required.

In summary, the main differences between aluminium composite panels and solid aluminium panels are:

Composition: ACPs consist of two layers of aluminium sheets with a core material, while solid aluminium panels are made of a single layer of aluminium.

Weight: ACPs are lighter than solid aluminium panels due to their layered structure.

Cost: ACPs are generally less expensive than solid aluminium panels.

Durability: Solid aluminium panels are more durable and resistant to impact and weathering than ACPs.

Applications: ACPs are commonly used in exterior cladding and signage, while solid aluminium panels are used in high-end architectural applications.
