The following factors need to be considered when choosing fire doors:
Flame-blocking performance: the main function of fire doors is to block the spread of flame and smoke, so their flame-blocking performance is the primary consideration for selection. According to different needs, you can choose the applicable fire protection level, such as 30 minutes, 60 minutes, 90 minutes and so on.
Material and structure: The material and structure of the fire door directly affect its fire performance. Common materials include metal, wood and composite materials, etc., while the structure involves the design and craftsmanship of the door frame, door leaf, door lock and other components.
Sealing performance: the ability to effectively isolate the spread of smoke and flame is one of the important functions of fire doors. Therefore, when choosing a fire door, it is necessary to consider its sealing performance, such as the fit between the door and the door frame, and whether there is a seal in the center part of the door.
Thermal radiation performance: fire doors need to be able to resist the high temperature radiation generated during fire. Consider the thermal radiation blocking performance of the fire door, including the radiation transfer coefficient and the limitation of temperature rise in case of fire.
Impact resistance: In the event of fire, fire doors may be subject to impact, so their impact resistance needs to be considered. The strength and stability of both the door and the door frame are factors that need to be taken into account when choosing a fire door.
Durability and corrosion resistance: fire doors are usually used for a long time, so they need to have good durability. At the same time, as fire doors are usually installed in places susceptible to corrosion and moisture, such as kitchens, basements, etc., so corrosion resistance is also a factor to consider.
Ease of use and safety: When choosing a fire door, you also need to consider its ease of use and safety. Fire doors should be easy to open and close and need to be equipped with an appropriate locking system to ensure the safety of personnel.
Price and brand: the price of fire doors will be affected by different factors, such as material, fire rating, production process and so on. You need to choose a suitable fire door according to the actual needs and budget. In addition, choosing manufacturers or products with better reputation and brand awareness can provide more reliable quality assurance.
Relevant standards and certification: When choosing fire doors, you can refer to the relevant standards and certification requirements. In China, fire doors should meet the requirements of the national standard GB 12955-2008 "Fire Doors for Building Use", while the commonly used standard in the European market is EN1634.
Installation and maintenance: After choosing fire doors, you also need to pay attention to their correct installation and reasonable maintenance. The installation of fire doors should comply with the relevant specifications, such as ensuring that the door frame is firmly fixed and the seals are intact. In terms of maintenance, regularly check the working condition of fire doors and door locks, and pay attention to keep the door clean and painted.
To summarize, the selection of fire doors should take into account the flame barrier performance, material and structure, sealing performance, thermal radiation performance, impact resistance, durability and corrosion resistance, ease of use and safety, price and brand, relevant standards and certifications, as well as the installation and maintenance of factors to ensure that the selection of the appropriate fire doors, and provide reliable fire protection.
