The mechanical and electrical installation project hanger system has experienced the journey from the most primitive welded steel section hanger, to the open C-channel steel assembly hanger, and then to the closed section square steel assembly hanger system. Our company is one of the first enterprises in China to upgrade the assembled hanger to square steel assembled hanger system to provide the market with better strength, higher safety and faster assembly speed of the hanger products. The main section of square steel support hanger system is closed section, in the same cross-section size of the support hanger system, compared with non-closed section such as angle, C-channel steel system, in terms of strength, stiffness, stability, torsion and other aspects of a greater advantage. Square steel assembled support hangers are now widely used in electromechanical installation projects in tobacco, automotive, electronics, commercial complexes, schools, rail transport, data machine rooms and other industries.
