Safety measures for fire doors and taboos for choosing manufacturers
Apr 07,2025
Fire doors refer to doors that can meet the requirements of fire stability, fire door integrity, and thermal insulation within a certain period of time. They are fire compartments with a certain fire resistance limit, located in fire compartments, evacuation stairwells, vertical shafts, etc. Fire doors not only have the function of ordinary doors, but also have the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.
Close the evacuation stairs leading to the corridor; The fire resistance requirements of the new national standard for enclosed elevator rooms and fire doors include doors leading to the front room and corridors, inspection doors for vertical pipeline shafts such as cable shafts, pipe shafts, smoke exhaust tunnels, and garbage tunnels, dividing fire zones and controlling the firewalls and doors on the fire partition walls of the building area. When it is difficult to install firewalls or fire doors in the building, fireproof rolling shutter doors should be used instead, and water curtains should be used for protection.
For example, equipment rooms (cylinder rooms, foam stations, etc.) should use Class A fire doors,) attached to the partition doors of high-rise civil buildings and ventilation and air conditioning rooms, and doors on the partition walls of basement rooms where people often stay or where there are many combustibles should use Class A fire doors; Due to limitations in conditions, it is necessary to install fuel and gas boilers, oil immersed power transformers, high-voltage capacitors, and oil filling switches. In high-rise buildings, doors on the partition walls of special rooms should use Class A fire doors. For households with special requirements for fire prevention, such as fire command centers, archive rooms, and valuable item warehouses, Class A or Class B fire doors are usually used. Residential doors in high-rise buildings often use fire and anti-theft measures.
Grade A fire door manufacturer: Three taboos when choosing a fire door manufacturer
1. Do not choose some "three no manufacturers" or "three no products" on the market just for cheap fire doors
Regarding how salespeople boast and assure you of the quality of their fire doors, please adhere to the principle of "not listening, not believing, not remitting". Please refer to the enterprise qualification certificate presented by the other party, and check the business license of the enterprise legal person, tax registration certificate, and testing report issued by the building materials testing center. Once these three certificates are complete, we can cooperate with confidence.
2. Do not lower the level of fire doors at will
In the absence of fire or other accidents, fire doors are no different in function from other doors, so we need to talk about some differences. Fire doors are heavier and higher in quality and appearance. However, don't forget that the original intention of choosing fire doors is that in the event of an accident, there is still room for recovery and a chance of survival. In fact, it is equivalent to buying oneself insurance, making oneself more at ease and more secure.
3. Don't spend money on buying burdens
No one wants to be a burden. Nowadays, many enterprises and units need to install fire doors, but they often cannot find the desired fire door manufacturer. Some brands may be good, but expensive, and the after-sales service is not very good. The after-sales attitude is cold. Some manufacturers are cheap and enthusiastic, but their qualifications are not complete, and they are not confident in purchasing and choosing. Therefore, it is important to pay attention to the after-sales service and service attitude of fire door manufacturers.
