Schematic diagram of wooden thermal insulation fire door structure
The materials used in the wooden heat-insulating fire-proof doors have been strictly inspected and purchased in accordance with the requirements of national standards. Regular sampling inspections are carried out to ensure that all raw materials are 100% in compliance with relevant raw material standards when they are put into production. We are well aware that fire doors cannot be equated with ordinary daily necessities. Any issues that may affect product performance and safety of use must be eliminated before production. During the production process, Qunsheng has established a complete set of quality control procedures. Every link can be strictly checked, and hidden dangers can be strictly investigated. Iron production disciplines and scientific production processes are used to ensure that the pass rate of product quality can reach 100%.
The difference between the fire resistance time and the thickness of the door leaf of the wooden heat insulation fire door:
Category |
Fire resistance time | Thickness of door leaf |
A |
1.5h |
50mm |
B |
1.0h |
45mm |
C |
0.5h |
45mm |
The difference between grades B and C: the size of the door frame material and the thickness of the door leaf
Wooden fire doors, like steel fire doors, are installed and used in public places, such as fire doors in stairways, elevator shafts, aisle partitions, and pipe shafts. The maximum specifications of Class B and C wooden fire doors are: single door 1100X2300(mm), double door 1800x2300(mm), the largest specification of Class A single door 1000X2100mm, double door 1500x2100mm, wooden fire door is beautiful, light, heat and sound insulation , Easy to process and other features. Class B and Class C can be equipped with door cover plate and door cover line.
material:
The door frame material is imported Liuan wood, and the frame material of the door leaf is domestic fir material.
All wood must be vacuum pressurized and flame-retardant treatment to reach the wood flame-retardant grade.
The inner filling material is made of non-toxic and harmless fire-proof and heat-insulating materials. Facing plywood generally uses eucalyptus plywood and melamine decorative panels for fire doors.
Expansion sealing materials are provided at the overlap of the door frame and the door leaf, the periphery of the door leaf and the overlap of the middle seam of the double door.
If the door leaf needs fireproof glass, the size of Class B and C fireproof glass is generally not larger than the size of Class A glass (350x300mm) (glass is 250x800mm).
colour:
The surface color of the wooden heat-insulating fireproof door should be determined according to the user's needs. Because the fireproof door is mainly used for public parts of the building, it is easy to be damaged during on-site construction. It is recommended not to paint before leaving the factory. When the project is almost completed, paint on the spot. To achieve a more scientific and humane service. The company's general regular colors are silver gray and dark red to choose from.
