Would you like me to explain the component requirements for wood fire doors? Wood fire doors are made using flame-retardant wood or flame-retardant wood-based furniture materials for the door casing, door frame, and door leaf’s surface panel. If the door leaf is filled, it must be packed with thermal insulation materials that are non-toxic and harmless to human health, and equipped with fire-resistant hardware accessories. In addition, fire doors come in different fire-resistance ratings.

Wooden fire-rated door Use flame-retardant wood or flame-retardant wooden furniture for door casings, door frame structures, and door leaf control panels. If the door leaf is filled, use thermal insulation materials that are non-toxic and harmless to human health, and equip the door with fire-resistant hardware accessories. In addition, fire doors come in various fire-resistance ratings. Generally, Wooden fire-rated door Applicable to the internal structural components of residential buildings, except for basement areas of villas, parking garages, electrical distribution rooms, main machine rooms, or other specifically designated areas—such as fire doors in public passageways. On the exterior of residential buildings, where certain areas may be exposed to fire doors, steel fire doors are typically used. This is because steel fire doors are more robust and resistant to damage than wooden doors, particularly in environments with harsh conditions. Additionally, steel fire doors often incorporate certain anti-theft features.
Wooden fire-rated door 3CF certification falls under the category of self-certification for fire protection products and is an integral part of fire protection product certification. As the relevant authorities have significantly stepped up market oversight and quality control of fire door systems, companies are facing increasing pressure from various fire safety spot checks. Consequently, fire door manufacturers are placing greater emphasis on product quality.
What are the regulations for wooden fire-rated door components? Let’s take a look together!
The thickness of hinges (hinges) used for fire doors shall not be less than 3 mm. Steel fire-resistant safety latches should be installed on the door leaf of the side of a double-fire door that is fixed and stationary relative to the other door leaf (if higher requirements apply). Flame-retardant properties of fire-resistant latches:
The fire-resistance rating of the fire-resistant locking device must not be lower than that of the fire door on which it is installed and used. During the fire-resistance test, the fire-resistant locking device must show no significant deformation or melting. No fire incidents should occur at the location of the fire-resistant locking device. Furthermore, the fire-resistant locking device should ensure that there is no displacement at the assembly point between the fire door leaf and the locking mechanism, and that the door remains in a well-closed condition.
Types of laminated glass embedded in fire doors:
For fire doors incorporating laminated glass, their fire-resistance performance must meet the requirements for Class A fire doors.
For fire-rated doors incorporating laminated glass, their fire resistance performance is... Need Meets the requirements for Class B fire doors.
For fire-rated doors incorporating laminated glass, their fire resistance performance is... Need Meets the requirements for Class C fire doors.
In addition, the spare parts for the re-inspection of fire doors also include fire-resistant locks, fire-rated door closing devices, and fire-rated sequence controllers, among others.
What are the installation specifications for wood fire doors?
1. Wooden fire doors should preferably be sliding doors that open and close smoothly and are equipped with an automatic release mechanism.
2. For use as fire evacuation passages Wooden fire-rated door It should be capable of being quickly unlocked in the event of a fire and open toward the direction of fire evacuation; locking mechanisms and latches are not suitable for installation.
3. Multi-leaf wooden fire doors with sub-frames must be able to close in sequence.
4. At the cut edges where the door frame of a wood fire-rated door overlaps with the steel reinforcement of the door leaf, a sealing groove should be provided, and a sealant strip made of flame-retardant material should be embedded therein.
5. When conditions permit, it is advisable to install the door leaf and door frame as a complete set, fitting all small hardware components first, and then assembling the entire set.
6. After the wooden fire-rated door is completed, it should be immediately coated with a layer of oil (oil-based varnish) to prevent moisture absorption and deformation.
7. For the installation of small hardware, use wood screws; steel nails must not be used as a substitute.
