Facade is the exterior protective enclosure of a building, non-load-bearing, hung up like a curtain, hence also known as suspended wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings.

Aluminum curtain wall panels offer excellent stiffness, light weight, and high strength; they are resistant to stains and easy to clean and maintain; installation is quick and simple, as they are formed in the factory, eliminating the need for on-site cutting and requiring only minimal fixation; they are 100% recyclable, making them environmentally friendly. Currently, this material is increasingly favored by architects and developers, emerging as the new favorite for building curtain wall materials.
