What are fire doors?
Before going to the uses of fire doors, we must have a correct definition of them. As the name suggests, fire doors prevent flames from entering the environment and can last up to 4 hours against fire.
Different materials are usually used in the structure of these doors, such as special coatings, steel sheets, stone wool or ceramics to increase its resistance to fire. Fireproof sealing rubber is also used around this door to completely surround the door and prevent the transfer of smoke to other parts of the building.
In fact, when these sealing tires are exposed to heat, their thickness will multiply and they will no longer allow smoke to pass through. Most of the time, fire doors are installed in the staircase or footpath.
When the occupants of a building want to leave the burning building, they use the emergency stairs. The presence of fire doors in these staircases makes the process of exiting the building faster. In fact, fire doors provide more opportunities to escape by not transferring fire and smoke to other floors of the building.
Fire doors are usually used in different places. such as:
- Residential and commercial buildings
- Departments and organizations
- Stadiums
- Refineries and power plants and...
- Hospitals and hotels
- Airports
In general, any large place where there is a possibility of fire should use fireproof doors to reduce the risk.
Most of the time, fireproof doors are made of special woods. In the past, the main wood used in the structure of fireproof doors was Russian wood. But since Russian wood could only last 60 minutes against fire, they replaced it with newer doors like steel doors. Steel doors are covered with different coatings in order to have high resistance in addition to beauty.
A very important point about fire doors is that according to the material used in them, their resistance to fire may be different. For example, some fireproof doors have used fireproof furnace colors, which creates an additional cover against fire.
A Fire-rated door may last from 20 minutes to 90 minutes against heat. Of course, the steel fire doors that are used in large buildings can withstand up to 240 minutes and do not melt. Standard fire doors have special requirements that increase their resistance to fire. We have discussed these requirements in another part of the article.

One of the best and most common fireproof doors available in the market are doors that have a wooden structure. As we said, in the past, Russian wood was used to make such doors, but today, other woods are also used. Of course, the frame of these fireproof doors must be metal. The thickness of wooden fire doors should be at least 5 cm.
Another thing about wooden fire doors is that no paint or cnc should be used in them.
Fire-rated door metal
As the name suggests, these doors are made of different metals. They may not have the unique beauty of fireproof wooden doors, but their resistance to fire is high.
Of course, it should be noted that metal fire doors are heavy and cannot be installed on simple metal frames. Usually, based on the humidity in the building, galvanized metal sheets or oil sheets are used to make these doors. Also, the inside of the structure of the fireproof metal doors is filled with rock wool to prevent the spread of fire.
At the same time, metal fire doors are installed using welding. The dimensions of these doors are usually standard and they are designed in 100 and 120 and 120 sizes.
Glass fire doors
Another of the most common fireproof doors available are doors that are made of a combination of glass and wood or glass and metal. Such doors are usually used in high-traffic public buildings. For example, hospitals or large factories can use glass fire doors. The price of these fireproof doors is high and usually it is not cost effective to use them in office and residential buildings.
Fireproof and unbreakable glass is usually used in the structure of fireproof doors. Also, the sealing strip around the glass is cut very carefully to prevent smoke from spreading to other parts of the building.
No matter how much we say about the importance of not spreading the smoke to other parts of the building, we still have not said enough. Because many times the emission of smoke prevents residents from escaping and causes loss of life.
