Technical Standards for Wooden Fire Doors (Wood Grain Finish)
For manufacturers and suppliers looking to meet global fire safety standards, understanding the technical specifications of wooden fire doors is essential. As a leading Chinese fire door manufacturer, we are committed to providing high-quality products that adhere to the latest fire door regulations and offer aesthetic flexibility with wood grain finishes.
1. Compliance with the Latest Fire Door Standards: GB12955-2008
Our wooden fire doors strictly comply with the GB12955-2008 standard, which sets out the technical requirements for fire resistance and safety. This ensures that our products meet the stringent fire protection regulations required in both residential and commercial buildings.
2. Door Frame Construction
The door frame is constructed using flame-retardant hardwood, which has been thoroughly dried and processed. The production process includes cutting, mortising, frame assembly, and the application of decorative veneers and fireproof seals. This construction enhances the door’s fire-resistant properties, making it a reliable choice for various fire safety applications.
3. Door Leaf Composition
The door leaf is crafted from wood that has been kiln-dried and processed to exact specifications. It features a core filled with perlite fireproof materials to provide exceptional fire resistance. The leaf is assembled and pressed in a cold press machine before being trimmed and fitted with hardware components. The final step involves applying a high-quality finish to ensure durability and aesthetic appeal.
4. Core Materials and Components
4.1. Hardwood Framework
The door frame and leaf framework are made from high-quality hardwood, which is inherently fire-resistant. This material provides structural integrity and contributes to the overall fire rating of the door.
4.2. Fireproof Board
Made from calcium silicate, the fireproof board is installed within the door leaf. It effectively blocks the spread of flames and provides thermal insulation, enhancing the door’s fire resistance.
4.3. Plywood and MDF Panels
Plywood is used as a lining material inside the door leaf. Medium-density fiberboard (MDF) is employed for milling and shaping purposes, ensuring a smooth and uniform finish.
4.4. Fireproof Seals
Fireproof seals are placed around the door frame. These seals expand when exposed to heat, sealing off the fire-affected area and preventing the spread of smoke and flames.
4.5. Perlite Fireproof Core
The core material is composed of perlite, which provides excellent fire resistance and helps prevent the door from warping under high temperatures.
4.6. Decorative Veneers
Wood veneers are applied to the surface of the door frame and leaf, offering various design options to match different interior styles.
4.7. Paint Finish
High-quality paint is used to coat the surface of the fire door, providing an additional layer of protection and enhancing the door’s aesthetic appeal.
5. Hardware Components
All hardware fittings meet the required fire resistance standards. Clients can choose the grade and brand of hardware based on the specific fire door requirements. Options include fire-rated hinges, handles, locks, and automatic door closers.
6. Fire Resistance Ratings
Our wooden fire doors are available in various fire ratings to suit different building regulations:
- Class A: 1.5 hours
- Class B: 1.0 hour
- Class C: 0.5 hours
These ratings indicate the door’s ability to withstand fire exposure for a specified period, providing adequate time for evacuation and fire control.
7. Door Thickness
The thickness of the wooden fire door is not strictly regulated, as long as it meets the necessary fire resistance criteria:
- Class A: 50mm
- Class B: 45mm
- Class C: 40mm
This flexibility allows for customization while still achieving optimal fire safety performance.
8. Surface Quality and Finish
The surface treatment of wooden fire doors involves a meticulous painting process, which includes two layers of primer, one layer of color paint, and two layers of topcoat. This multi-layer approach results in a smooth, uniform, and highly durable finish with a range of wood grain options, such as black walnut, to complement different design aesthetics.
9. Key Features of Wooden Fire Doors
Wooden fire doors offer versatile design options, with various styles and wood grain finishes available to match any architectural theme. Their advantages include:
- Aesthetic Appeal: The natural wood grain and customizable finishes enhance the overall look of interiors.
- Moderate Price: Wooden fire doors provide an economical option without compromising on quality or fire safety.
- Customization: Various designs and finishes can be tailored to suit specific requirements, making them a popular choice for both residential and commercial projects.

II. Door Leaf Installation
- Positioning the Door Leaf
- Place the wooden fire door leaf into the door opening and check the fit between the door leaf and frame. The gap between the door leaf and frame should be within the specified range to ensure proper functionality and fire resistance.
- Leveling the Door Leaf
- Use a spirit level to adjust and align the door leaf horizontally and vertically.
- Securing the Door Frame
- Fix the door frame to the wall using a screw cutting machine and secure it with expansion bolts.
- Handle and Lock Installation
- Confirm the swing direction of the door and install the door handle and lock. Ensure that the hardware is properly aligned and functions smoothly.
III. Door Frame Installation
