Aluminum sheets can be used for building exteriors in earthquake-prone areas, but they must be properly engineered and installed. Aluminum is lightweight and flexible, which can be advantageous in withstanding seismic forces. However, it's crucial to ensure that the aluminum is reinforced with a robust structural system that can distribute the forces during an earthquake. The design must also comply with local building codes and seismic regulations. It's recommended to consult with structural engineers and architects experienced in earthquake-resistant design to ensure the safety and durability of the construction.
