Additionally, it explores the preparation of anti-bending sand-grain powder coatings for fire doors, highlighting the significance of material selection and application techniques in enhancing the durability and fire resistance of these critical safety features.
1. Introduction
The installation of steel fireproof doors is a critical component in ensuring the safety and integrity of buildings in the event of a fire. This paper presents a comprehensive guide provided by Yunnan Guangdun Door Industry Co., Ltd., a leading China fire door factory, on the installation process, focusing on the use of multi-door access systems and the application of innovative anti-bending sand-grain powder coatings to enhance the performance of fire doors.
2. Tools and Materials
The installation process begins with the assembly of necessary tools and materials, including an electric hammer, plug gauges, plumb bobs, red thread packages, ink, a small electric saw, welding rods, bolts, and cement mortar. These tools ensure precision and efficiency in the installation process.
3. Pre-installation Checks
Prior to installation, a thorough inspection of the door frames is mandatory to ensure compliance with the required models, dimensions, and to check for any defects such as twisting or bending. Any identified issues must be addressed through replacement or repair to ensure optimal installation conditions.
4. Installation Procedures
The installation process encompasses several critical steps:
- Positioning and Alignment: Drawing lines to mark the installation position within the doorway according to the design drawings, ensuring the door frame is correctly aligned with the building’s structural requirements.
- Frame Setting and Correction: Adjusting the door frame to achieve vertical and horizontal alignment with tolerances of ≤2mm for verticality and ensuring consistent dimensions across the frame.
- Securing the Frame: Temporarily securing the frame with bolts, followed by a detailed check to confirm the accuracy of the installation dimensions, with allowable tolerances of ≤1.5mm for frame size and ≤2.0mm for diagonals.
- Door Installation: Fitting the door leaf into the frame, adjusting its position, and ensuring it is correctly aligned in all directions before permanently securing the frame to the building structure.
- Gap Sealing and Grouting: Sealing gaps between the door frame and the wall with rock or mineral wool, followed by grouting around the frame with C15 fine stone concrete to ensure a firm and stable installation.
- Finishing Touches: Applying anti-bending sand-grain powder coatings to the door surface to enhance its fire resistance and durability, followed by a final inspection to ensure the door operates smoothly and meets all required safety standards.
5. Conclusion
The installation of steel fireproof doors is a meticulous process that requires precision, expertise, and the use of specialized materials and coatings. Yunnan Guangdun Door Industry Co., Ltd., as a prominent China fire door factory, demonstrates its commitment to safety and quality through its detailed installation process for multi-door access systems and the application of anti-bending sand-grain powder coatings. These practices not only ensure the functional integrity of fire doors but also significantly contribute to the overall fire safety of buildings.
