Fire Shutter Technical Standards and Requirements

As a leading fire shutter manufacturer in China, Guangdun Door Industry Co., Ltd. is committed to providing high-quality fire shutters that meet the highest safety standards. Below is an overview of the key technical requirements and installation guidelines for fire shutters, with a focus on compliance with industry regulations and safety standards.

1. Fire Shutter Construction Requirements

Fire shutters should adhere to the technical specifications outlined in the Fire Shutter Technical Standards (GB14102-2008) and must be equipped with both fire and smoke protection.
Fire shutters must integrate with temperature-sensitive and smoke-detection alarm systems for enhanced safety.
They should automatically descend in case of fire, with a delay mechanism (1-10 minutes) to allow for emergency evacuation.
The shutters should also have emergency manual override features and can be operated both automatically and manually as required.

2. Fire Shutter Appearance and Material Requirements

All metal parts should be free from defects such as cracks, dents, or visible rough edges and must be treated with anti-corrosion coatings for durability.
The inorganic fiber composite curtain (used in the shutter) must be defect-free, ensuring a uniform weave and smooth surface.
Fire shutters made of inorganic fiber composite materials must demonstrate high fire resistance with B1-level textile burning performance, ensuring they meet national fire safety standards.
All components, including guide rails and slats, must be precisely manufactured to avoid misalignment and to ensure smooth operation.

3. Materials for Fire Shutter Construction

All raw materials used in the manufacturing of fire shutters, including steel and inorganic composite fiber, must comply with the relevant national standards or industry norms.
The material strength of the inorganic fiber curtain should be robust, ensuring it meets the specified tensile strength requirements for both warp and weft directions.
The shutter curtain’s decorative fabric or base cloth must maintain elasticity at temperatures up to 50°C and should not become brittle or adhesive at low temperatures.

4. Fire Shutter Key Dimensions and Tolerances

The guide rails should have specific tolerances, with the slot depth and width each requiring a precision of ±2mm.
All roller and curtain assembly parts should be correctly aligned, with a gap tolerance of no more than 3mm between sections.

5. Installation and Performance Requirements

For large openings (widths between 3000mm and 5000mm), the guide rails must be securely embedded with a depth of at least 50mm to ensure the stability of the fire shutter.
The curtain should be supported by high-temperature resistant stainless steel wires at regular intervals to maintain structural integrity.
Fire shutters must operate smoothly within their guide rails without any jamming or impact, providing seamless function in both residential and industrial environments.

6. Control and Safety Features

The fire shutter control system must be compatible with national fire detection equipment and undergo rigorous testing and certification.
Smoke-proof and fire-proof mechanisms should be incorporated into the guide rails and door frame to prevent the spread of smoke and fire.
