Description：The national standard GB50045-95(2005 edition)"Code for FireProtection Design of High-Rise Civil Buildings"stipulates in section5.1.6:"Corridors with smoke exhaust facilities and rooms with a clear height not exceeding 6.00m should use smoke curtains, partition walls, or beams protruding no less than 0.50m from the ceiling to divide smoke control zones.The building area of each smoke control zone should not exceed 500 square meters, and smoke control zones should not cross fire compartments."Based on this, our company has developed a series of smoke curtain products, categorized into fixed and movable types. Smoke curtains are smoke barriers made of non-combustible materials that hang down no less than 500mm from the ceiling.Movable smoke curtains refer to those that automatically descend in the event of a fire due to the action of smoke detectors, heat detectors, or other control equipment.
