What are three metal curtain wall systems?

Three common metal curtain wall systems are aluminum curtain walls, which are lightweight and corrosion-resistant; steel curtain walls, known for their strength and durability; and zinc curtain walls, valued for their aesthetic appeal and natural patina. Each system allows for flexible design and can accommodate large spans of glass, providing both structural support and energy efficiency. These systems are widely used in modern architecture for commercial buildings, offering both functionality and visual impact.
