I.Fire-resistant doorIs it a swing door or a sliding door?
Fire-resistant doors are hinged doors, as hinged doors are required to meet relevant product standards in China's fire safety regulations. Specifically, the standard "Fire-Resistant Doors" (GB12955-2008) primarily applies to hinged fire-resistant doors. Therefore, currently available products are exclusively hinged fire-resistant doors, and there are no fire-resistant doors in the form of sliding doors, rotating doors, suspended doors, swing doors, or folding doors.
Are there any double-opening fire doors available? Currently, all fire doors are of the hinged, inward-opening type. These fire doors consist of a door frame, door leaf, and fire-resistant hinges and locks. The door leaf is perpendicular to the ground, and the opening and closing action is achieved via hinges, with the door leaf rotating in only one direction. There are no double-opening fire doors available.
Two. What are the different methods for opening fire doors?
Fire-rated doors are classified based on their opening method, primarily as hinged fire-rated doors and sliding fire-rated doors. However, in China, the only type of fire-rated door available is the hinged type. While sliding fire-rated doors exist in other countries, they are not permitted in China.
According to the new version of the National Standard GB 12955-2008, which came into effect on January 1, 2009, the fire door has passed the fire resistance test according to the specified method and has obtained verification certificates and authorization marks issued by the Economic Bureau Standard Inspection Bureau. This fire door is defined as "any combination of fire door leaves, door frames, hardware, and other components that can provide a certain level of fire protection for the opening."The NFPA and IBC codes define fire doors as "any combination of fire door leaves, door frames, hardware, and other components that can provide a certain level of fire protection for the opening."
