I. Structural Elements


1. Door Leaf Structure:

The door leaf of entry fire doors is typically made of steel plates, non-combustible materials, or wood containing flame-retardant substances. These materials possess excellent fire resistance, can withstand high temperatures, and inhibit the spread of flames.


2. Door Frame:

The door frame is the supporting structure of the door leaf, usually made of steel plates, non-combustible materials, or wood containing flame-retardant substances. It ensures the stability of the door frame and provides strong fire resistance.


3. Fire-Resistant Filling Materials:

Fire-resistant materials such as rock wool, perlite, and calcium silicate boards are filled inside the door leaf. These materials insulate heat and smoke, enhancing the fire rating of the door.


4. Sealing Strips:

Sealing strips at the door frame and door leaf seams are made of high-temperature-resistant and flame-retardant materials, effectively preventing the penetration of harmful gases during a fire and ensuring a tight seal.


5. Fire Door Lock:

Fire door locks possess fire-resistant features and function normally during a fire, ensuring the door leaf remains closed.


6. Emergency Escape Lock:

Also known as Panic Bar Device, trim lock, fire door lock, exit lock, push bar lock. It is commonly used in corridors. In the event of a fire, individuals can quickly open the fire door by pressing the push bar lock on the fire door.


7. Fire Door Closer:

The fire door closer ensures that the fire door remains closed, guaranteeing a tight closure during a fire to achieve the desired fire-resistant effect.


8. Smoke and Dust Seals:

Smoke and dust seals automatically rise when the door is open, hiding within the door leaf, facilitating easy opening. When the door is closed, they automatically extend, ensuring a tight closure between the door leaf and the frame, effectively preventing dust and smoke.

II. Material Selection


1. Steel Material:

Steel is a commonly used material for fire doors, offering excellent fire resistance and strength, maintaining stability at high temperatures. Steel material is suitable for making door frames and door leaves, ensuring the overall stability of the door.


2. Fire proof Wood material:

Wood, after flame-retardant treatment, can also meet the requirements of fire doors. Flame-retardant treated wooden door leaves are less likely to burn and are suitable as a material for door leaf production. Additionally, wood provides a natural and aesthetically pleasing look, catering to various interior design styles.


3. Fire-Resistant Glass:

If there are windows on the entry fire door, fire-resistant glass should be chosen to ensure it acts as a barrier to fire and smoke during a fire, while maintaining transparency.


4. Fire-Resistant Paint:

Entry fire doors are often coated with fire-resistant paint on the surface to enhance their fire resistance and improve the fire rating.


In conclusion, the construction and material selection of entry fire doors directly impact their fire resistance. Choosing the right materials and implementing a reasonable construction can ensure that entry fire doors perform optimally during a fire, protecting lives and property. Selecting suitable entry fire doors is a crucial step in ensuring home safety.
