Technical Requirements for Fire Doors and Hardware Components
As a leading China fire door manufacturer, ensuring compliance with national and international standards is essential for us to meet the needs of our clients in various industries. In this document, we outline the critical technical requirements for fire doors and their hardware components, based on the latest fire protection regulations and best practices. This guide serves as a valuable resource for procurement officers, contractors, and construction professionals seeking to optimize fire door installations.
1. Product Quality Requirements:
1.1 Fire Door Product Quality:
- Compliance with Standards: All fire doors and associated hardware must meet the design specifications and national standard GB12955-2008 for fire doors. This includes obtaining product certification and identity marks from authorized fire safety bodies.
- Design Specifications: The fire doors’ type, color, and fire resistance level must adhere strictly to the project’s design requirements.
- Fire Resistance: The fire door’s fire rating must meet or exceed the specified fire protection grade to ensure maximum safety in case of a fire incident.
As a fire door manufacturer, we guarantee that our products comply with these stringent standards, providing reliable solutions for fire safety in construction projects.
1.2 Installation Requirements:
- Threshold-free Fire Door Installation: For fire doors without thresholds, the door frame must be embedded at least 15mm below the finished floor level.
- Frame Adjustment: After installation, the door frame must be corrected for vertical alignment without using metal hammers. The frame should remain straight and undistorted.
- Cement Filling: The gap between the door frame and wall must be filled with cement mortar and allowed to cure for at least 24 hours before installing the door leaf.
As a China fire door manufacturer, we focus on precision installation, ensuring that the gap dimensions between the door leaf and frame adhere to the following:
- The hinge side gap should not exceed the design tolerances.
- The lock side gap should also remain within specified tolerances.
- The gap between the door leaf and top frame should be no larger than 3mm.
- For double-leaf doors, the gap between leaves should not exceed 3mm, while the bottom gap should not exceed 9mm.
- The contact gap between the door leaf and frame must be no larger than 3mm on all sides.
| Item times | project | allowable deviation (mm) | method of calibration | |
| 1 | Diagonal length difference of the slot | 2,000 mm (door height) | 4 | Check with a steel ruler |
| 2,000 mm (door height) | 5 | |||
| 2 | Positive and side verticality | 3 | Check with a vertical test ruler | |
| 3 | Horizontal degree of cross frame | 3 | Check with a lm level ruler and a stopper | |
| 4 | Horizontal frame elevation | 5 | Check with a steel ruler | |
| 5 | Vertical deviation from the center | 5 | Check with a steel ruler | |
These installation guidelines are critical to ensuring the integrity and performance of the fire door, which we, as an established fire door factory in China, take seriously.
2. Inspection and Testing:
Before installation, all materials must undergo rigorous inspection by the contractor, supervisor, general contractor, and construction team. This ensures that only high-quality, certified products are used. The fire door supplier must provide valid production licenses, quality certificates, and user manuals for all products.
3. Visual Quality Requirements:
- Functional Testing: Fire doors must open and close smoothly, with no visible scratches or damage.
- Surface Finish: The surface must be clean, free from significant dents or deformations, and show no signs of impact damage.
- Noiseless Operation: The door should open and close without any noise, and the leaf must close tightly.
- Hinge and Hardware: Hardware, such as hinges and locks, must be securely installed, free from rust, and easy to use. Any damaged parts should be replaced immediately.
At our fire door factory, quality control is a priority, and we work closely with construction professionals to ensure all fire door installations meet these high standards.
4. Finished Product Protection:
- Transport and Packaging: Products must be transported and packaged with care to avoid deformation or damage. Fire doors should be stored in ventilated, dry conditions, protected from sunlight, moisture, and corrosion.
- Storage Precautions: When storing fire doors, care must be taken to ensure they are placed on level surfaces, with proper support to prevent bending. Fire door frames should not be stacked higher than 1.5 meters, and door leaves should not exceed 1.2 meters in height.
- Protective Film: Fire doors must remain covered with protective film until final inspection and project handover. Damage to the doors during construction is the responsibility of the installation contractor.
Our China fire door manufacturing facility takes extra steps to ensure that our products are protected during transportation and installation, reducing the risk of damage and ensuring they meet project deadlines.
5. Door Manufacturing and Installation:
- Positioning: Fire door positioning must be precise, ensuring alignment with the design’s centerline.
- Handling and Transportation: Fire doors must be carefully transported to the installation site and inspected for any potential damage.
- Opening Direction: Fire doors should open in the direction of evacuation, and their swing should allow them to open to a 90-degree angle if positioned near a wall.
6. Standards and References:
This document refers to several important standards that must be followed to ensure fire door quality and performance. These include but are not limited to:
- GB12955-2008 – Fire Doors
- GB/T708-2006 – Cold Rolled Steel Sheet and Strip Dimensions and Tolerances
- GB/T709-2008 – Hot Rolled Steel Sheet and Strip Dimensions and Tolerances
