Large ventilation and smoke exhaust ducts carry heavy weight and may swing and collapse during earthquakes, blocking evacuation routes.
Senji duct seismic bracing uses unistrut modular strut to provide longitudinal and lateral restraint for rectangular air ducts and smoke ducts. Factory prefabricated parts are bolt-assembled without damaging duct insulation. Widely used in commercial complexes, underground parking and smoke exhaust systems. Corrosion-resistant products with engineering calculation reports comply with international seismic codes.
