Z-shaped steel is a type of cold-formed thin-walled steel, named for its "Z"-shaped cross-section. It is mainly used in large steel structure factories and other building structures. It features high strength, high strength-to-weight ratio, durability, high precision, and ease of connection. Furthermore, due to the characteristics of its cross-sectional shape, it can achieve connections in different directions in large steel structures, making it an economical, efficient, and multifunctional building material.
