Henan fire door refers to the door that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. supply Fire door It is a fire compartment with certain fire resistance, which is located in fire compartment, evacuation staircase, vertical shaft, etc. In addition to the function of ordinary doors, fire doors can also prevent the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of people. Henan fire doors are certified by the Ministry of Economic Affairs of the Ministry of Fire Protection. According to the new version of the standard for fire doors GB_12955-2008 implemented on January 1, 2009, those who pass the fire resistance test of fire doors and have obtained the registration certificate and authorized logo issued by the Bureau of Standards and Inspection of the Ministry of Economic Affairs are called fire doors. Fire door Price The fire door defined in the American NFPA and IBC codes is "any combination of fire door leaves, door frames, hardware and other accessories that can jointly provide a certain degree of fire protection at the opening."

Product classification of Henan fire door manufacturers. Fire door manufacturers combine the advantages of traditional door furniture and carry out innovative development of new door furniture. supply Fire door The steel fireproof door has all the properties of the traditional anti-theft door and can be used in home life. The door furniture is made of superior metal composite materials, and is mainly made of aluminum alloy and stainless steel, so it has strong hardness and solves the problem of rust. It can produce chemical reaction at high temperature, generate oxygen and control the ignition point. The steel fireproof door can play a good role in fire prevention and heat insulation, which is also a performance that other metal doors do not have. The metal itself has good thermal conductivity. The scientific and technological achievements adopted by the steel fireproof door can withstand impact without deformation, which can bring greater safety to the home life. At the same time, it can also be used as the door of the factory, which can not only protect the product from fire but also prevent the product from being stolen. Fire door Price Fireproof door manufacturers also launched wooden fireproof doors, which are mainly used indoors. The exquisite carved patterns add to life. It is a new breakthrough in the series of fireproof door products. It is processed from non combustible wood materials, which can play a role in fire prevention; The steel fire door is the original fire door product, which is mainly used in factories and their gates. The steel door made of superior aluminum alloy changes the thermal conductivity of metal, which can play a good role in fire prevention. The quality of the door made of all metal is good; The steel wood fire door is the perfect combination of steel and solid wood. It is light in quality and elegant in appearance. It has played a good role in many fields of life. It can be said that it is a desirable product in the fire door series.

Analysis on the influence of fire resistance time of henan fire rolling shutter door on the coming of fire hazard in building fire protection design, ensuring safe evacuation of personnel is the primary premise of fire protection design, and the important standard of fire safety evacuation is time. supply Fire door China has made detailed regulations on the setting of evacuation width, evacuation distance, various fire-fighting facilities and other elements in various fire technical specifications. These are hard standards for fire design and review, but in fact, these requirements are not isolated from each other and created out of thin air. They all serve to ensure the safe evacuation of people, The setting requirements in the specification mostly come from the calculation of the fire safety evacuation time, so understanding the fire safety evacuation time is the basis and premise for the design and installation of fire rolling shutter doors. The so-called safe evacuation of Henan fire shutter door refers to the evacuation of people to a safe area before the fire develops to threaten the safety of people, that is, to make the safe evacuation time less than the time of danger, which is the benchmark of evacuation design, and all other design elements should serve this goal. The main factors that can cause danger to people in fire are high temperature, toxic smoke, building structure collapse and so on. The high temperature is mainly caused by thermal convection and radiation. When the air temperature reaches 100 ℃, ordinary people can only endure it for more than 10 minutes. When the temperature exceeds 200 ℃, people will die within 5 minutes. The harmful gases in the smoke mainly include carbon monoxide, carbon dioxide, formaldehyde, acetaldehyde, hydrogen cyanide, etc. The common carbon monoxide content in the air as long as 1%, people will lose consciousness after breathing several times, which will lead to death. At present, a large number of polyethylene, polystyrene and other building materials will produce toxic smoke after combustion. Smoke will not only cause poisoning, but also reduce the visibility of people in dense smoke due to the dimming effect of smoke. When the visibility is less than 0.5m, the moving speed of people is equivalent to the walking speed when they lose their vision. Fire door Price Henan fireproof rolling shutter door usually has a fire resistance limit much higher than the time of smoke spreading and flowing, but if flammable and combustible decoration materials are used in the evacuation passageway, it may also burn rapidly.

Why is Henan fire rolling shutter an indispensable facility? Why is fire rolling shutter an indispensable facility. supply Fire door The types of fire rolling shutter doors in Henan mainly include composite steel fire rolling shutter (fire and smoke prevention), inorganic super grade fire rolling shutter (double track double shutter), steel composite water spray steam fog fire rolling shutter, steel composite lateral fire rolling shutter, steel composite horizontal fire rolling shutter, inorganic super grade folding fire rolling shutter and fire rolling shutter with various doors. The fireproof rolling shutter door, as well as the firewall, functions as a horizontal fireproof partition. It is composed of 13 parts, such as shutter, base plate, guide rail, support, reel, box, control box, door rolling machine, limiter, door header, manual quick release switch device, button switch and safety device, and is generally installed at the position that is not convenient for firewall separation. For example, open elevator halls, escalators, wide business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings that cannot use fireproof doors and windows. Fire resisting rolling shutter door has been widely used in building engineering to make fire separation. Fire door Price Henan fireproof rolling shutter door is an indispensable fire prevention facility in modern high-rise buildings. In addition to the function of ordinary door, the fireproof door has the special functions of fire prevention, smoke separation, suppression of fire spread, and protection of personnel evacuation. It is widely used in high-rise buildings, large shopping malls and other crowded places.

What are the requirements for the opening direction of the door of Henan Refuge Room? Fire doors play an important role in life. The opening direction of fire doors is very important. The Code for Fire Protection Design of Tall Buildings has clearly stipulated that the stairwell should be opened in the direction of evacuation, such as the stairwell should be opened in the direction of the staircase lobby, so as to facilitate the evacuation of people. supply Fire door In addition, the front room is generally a place of refuge and an evacuation passageway. In case of a fire, positive pressure air supply is required. If it is not installed in the above opening direction, the air pressure may open the fire door, causing fire and smoke leakage. 4.
