A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is mainly used as an opening door at firewalls, stairwell entrances, evacuation routes, pipe shaft openings, etc. A fire door is usually used to protect people safety. When a fire breaks out, it stops the spread of fire and smoke for a certain period of time, ensures the safe evacuation of people and acts as a seal when the positive pressure air supply system is in operation. The choice of hardware is also an important aspect in order to ensure the quality of the fire door. Since the fire door is special for fire protection, its accessories must of course also be special for fire protection, so the choice of hardware for the fire door must be strict. Whether the installation is reasonable and whether the management is appropriate and in place is directly related to the fireproof effect of the fire door.
By understanding the importance of fire doors in buildings and discussing what to look for when designing, installing and using fire door hardware to ensure that fire doors are effective in preventing fire in the event of a fire. The fire door hinge is the centrepiece of the fire door suspension system. It is responsible for opening and closing the door for everyday use. It withstands the temperature of the flames in the event of a fire, ensures the function of the fire door and protects people from using the fire door to escape.
In order for fire door hinges to function properly at critical times, the user must do a good job of maintaining the fire protection hardware on a daily basis. We analyse this from the following points.

1. Particularity of fire door hinge
The greatest advantage of the fire door hinge is that it does not deform in high temperature environments and has a robust structure. In the event of a fire, it opens and closes the fire door properly, ensuring the safety of building personnel. D and D HARDWARE's fire rated door hinges can withstand temperatures in excess of 1000 degrees Celsius. The door is warped and charred, and there are often considerable air pressure differences on both sides of the door. Ordinary hinges deform quickly. Fire-resistant hinges can pass the resistance test at 1000 ° C for 180 minutes, and then exceed the hose flow test: a test of 3 minutes. In the process, the door is repeatedly subjected to the impact of water under pressure. UL and CE certification tests still work and allow the door to open and close normally.
2. How to maintain fire door hinges daily
When installing fire door hardware, qualified products must be selected and must not lower the fire door's rating and be installed in strict accordance with the specification requirements.
Many people may have misconceptions about hardware. The hardware fittings of fire doors are rust and wear resistant materials, as long as they are properly installed. In daily life, without attention to maintenance, the hardware will oxidise and electrolyse, or suffer certain losses due to the environment. Fire door hinges, as the most commonly contacted hardware, directly affect the service life of fire doors, so every small detail cannot be ignored.
The following are the maintenance items after installing the fire hinge:
2-1. SUS316 stainless steel hinges are recommended for use in coastal areas. Note that the hinge page should be kept dry during use. If it gets wet, it should be wiped away in time to avoid the formation of watermarks or rust.
2-2. Do not use Stainless steel brush or hardened cloths to wipe. Do not use chemical cleaning agents or acidic liquids to avoid damaging the surface, causing scratches and erosion.
2-3. Use engine oil to lightly tap the gap in the hinge, wipe the hinge clean with a paper towel, and then repeat the opening and closing until the excess oil in the hinge is discharged. Wipe clean again. In order to avoid prolonged noise during hinge rotation, it is recommended to use it every 3 months.
2-4. Avoid hanging large and heavy items at the direction end of the lock body of the door, so as not to increase the lateral tension of the hinge.
2-5. If it is installed in a place with frequent or strong use, it should be regularly checked whether the screw is loose. It is recommended to check every 3 months.
A large part of the life of a fire door depends on the maintenance of the door's hardware. To ensure the functionality of your fire doors, you need to know how to maintain the fire door hardware. Everyday fire doors and door hardware need regular cleaning and maintenance in order to function better in the event of a fire. Well-maintained fire hinges provide long-term fire protection, enabling fire doors to function at their best and ensuring the safety of building life. This is the need to maintain fire door hinges.
D and D HARDWARE's fire rated hinges meet UL and CE testing requirements for maximum performance in educational, medical, hospitality, residential and commercial applications. D and D HARDWARE can also provide detailed and professional hardware matching solutions to suit individual situations.
