Aluminum is widely used in building curtain wall structures. Its lightweight nature significantly reduces the self-weight of the curtain wall compared to steel, lowering the load on the main structure and foundation costs. For example, using aluminum profiles in high-rise curtain walls can effectively reduce the overall weight of the building.
Aluminum is highly corrosion-resistant, resisting the erosion of acid rain, sulfur dioxide, and salt spray in the atmosphere, reducing maintenance costs and extending service life, eliminating the need for frequent anti-corrosion coating. Its good processing performance allows for the manufacture of various complex shapes of curtain wall frames and decorative components, such as curved and irregularly shaped profiles, meeting diverse architectural design needs. Furthermore, aluminum has excellent recyclability, aligning with modern sustainable building development concepts.
In addition, through reasonable alloy design and heat treatment processes, the strength and stiffness of aluminum in curtain wall structures can be improved, ensuring the safety and stability of the curtain wall under wind loads and seismic forces, and enhancing the building's appearance and energy-saving performance.
