The manufacture of fire doors is a key process in ensuring fire safety. Precision engineered with specialized materials, these doors comply with strict regulations to protect lives and property.
Materials used in the manufacture of fire doors
Fire resistant materials
Common materials include steel, treated wood and special heat-resistant glass. Each is selected according to the specific needs of the project.
Types of finishes and special treatments
Doors can receive additional fire-resistant treatments, such as intumescent paint coatings, to improve their fire resistance.
Design and technical specifications
Classification according to fire resistance
Ratings such as EI30, EI60 or EI120 indicate how long the door can withstand fire, protecting lives and property.
Thermal and acoustic insulation standards
In addition to resisting fire, many fire doors offer thermal and acoustic insulation, improving the functionality of the building.
Stages of the fire door manufacturing process
- Selection of certified materials
The first step is to choose materials that meet international and local standards to ensure quality.
- Cutting and assembly of parts
Door parts are cut with precision tooling and carefully assembled to ensure a perfect fit.
- Application of flame retardant treatments
The components are subjected to treatments that increase their fire resistance, such as the application of intumescent paint coatings.
- Quality testing and certification
The doors are thoroughly tested in accredited laboratories for strength and functionality.
Applicable international and national regulations
International standards
Standards such as EN 1634-1 and NFPA 80 establish the technical requirements for the manufacture of fire doors.
Local regulations
In Spain, the Technical Building Code (CTE) regulates the installation and use of these doors in buildings.
Common errors in the manufacturing process
Lack of quality control
Failure to perform thorough testing can compromise safety and lead to rejection of certification.
Use of non-certified materials
Non-approved materials can jeopardize the effectiveness of fire doors.
Fire doors maintenance and recertification
Recommended frequency of inspections
Annual inspections are required to verify the functionality of the fire doors.
Replacement of worn components
Intumescent gaskets and other elements should be replaced regularly to maintain effectiveness.
Conclusion
The manufacturing process of fire doors is essential to ensure safety in buildings. From material selection to final certification, each step is crucial to meet quality and protection standards.
