Wooden Fire Doors: Technical Standards and Installation Requirements
As a leading Chinese fire door manufacturer, we ensure that our wooden fire doors meet the highest standards of safety and quality. Wooden fire doors play a crucial role in fire protection, combining the natural appeal of wood with advanced fire-resistant properties. This article outlines the technical standards and installation requirements that our wooden fire doors adhere to, ensuring compliance with industry regulations and maximizing safety.
Compliance with GB12955-2008 and Fire Safety Standards
Our wooden fire doors are meticulously crafted to meet the General Technical Standards for Fire Doors (GB12955-2008), along with other relevant fire safety regulations, acceptance standards, and design requirements. The fire resistance ratings for our wooden fire doors are as follows:
Class A: Not less than 1.5 hours
Class B: Not less than 1.0 hour
Class C: Not less than 0.5 hours
These fire ratings ensure that our wooden fire doors provide reliable protection in various fire scenarios, making them suitable for a wide range of applications.
High-Quality Materials and Construction
Our wooden fire doors are constructed using premium fire-retardant wood for the door frame, door leaf frame, and internal framework. The door frame and the junction between the door leafs are equipped with fireproof adhesive strips and slots for fire-expanding seals, ensuring that our products meet all fire safety regulations. This attention to detail ensures a tight seal, preventing the spread of smoke and flames in the event of a fire.
Inside the door leaf, we use fire-resistant materials such as perlite, which is packed tightly between the perlite and the door leaf framework to enhance the door’s fire insulation properties. For double-leaf doors, we incorporate overlapping plates, further enhancing the fire-resistant capabilities of the door.
Installation Process for Wooden Fire Doors
Door Frame Installation
Preparation: The door opening should be prepared to ensure that the door frame is vertically aligned on both the front and side surfaces. The bottom of the frame should be 520mm above the building’s zero level line, with the frame embedded 20mm into the ground. If discrepancies arise between the zero line and the site conditions, the installation height should be coordinated with the building contractor.
Fixing the Door Frame: After filling the door frame with cement mortar and allowing it to set, the frame can be installed. For a door height of 2100mm, six fixing points are required, evenly distributed along the vertical frame and secured with expansion bolts. The upper and lower points should be 200mm from the ends, with the middle points evenly spaced. For a door height of 2400mm, eight fixing points are required. If the wall consists of hollow bricks with pre-embedded fixtures, the location of the fixing points can be adjusted based on site conditions.
Door Leaf Installation
Before installation, ensure that the wooden fire door leaf dimensions match those of the door frame. The upper hinge should be placed 150mm from the top, the middle hinge 260mm from the upper hinge, and the lower hinge 1080mm from the middle hinge. For door frames with a bottom frame and an opening height less than 1800mm, two hinges should be used for fixing.
Proper alignment is crucial. Determine the hinge positions on both the frame and door leaf, carving the hinge slots accurately. Avoid cutting slots on only one side (either the frame or the leaf). Use 5×40 screws for fixing, inserting the screws to one-third depth with a hammer before fully tightening with a screwdriver. Hammering the screws in fully in one step is not recommended.
