The fire shutter door is a kind of fireproof and heat insulation facility suitable for the large hole of the building. The product has played a certain role in the design and installation.
Fire shutter doors are widely used in fireproof partitions of industrial and civil buildings. They can effectively prevent the spread of fire and ensure the safety of life and property. They are an indispensable fire protection facility in modern buildings.
Double skin fire rated roller shutter: The door piece is made of double-sided 0.8mm galvanized steel plate, which is filled with fireproof cotton inside. The guide rail is made of 1.5mm galvanized steel plate and fireproof rubber strip. The guide rail width is 100mm. The box is formed by 0.8mm galvanized steel sheet. CCC certified motor and electric control box.
❈ Composite roller shutter quality: The two roller shutters of the steel fire shutter composite roller shutter are firmly connected, and the filler is filled and enriched.
Single skin fire rated roller shutter: The door piece is formed by single-layer 1.0mm galvanized steel plate. The guide rail is made of 1.5mm galvanized steel plate and fireproof rubber strip. The guide rail width is 100mm. The box is formed by 0.8mm galvanized steel sheet. CCC certified motor and Electric control box with its own induction spray system.
Mineal fibre compositus fire resistant shutter: The roller shutter is made of a double-guide rail double-roller shutter structure. The single-layer roller shutter adopts radiation-proof cloth and an aluminum silicate fireproof blanket and glass fiber woven fabric and molded splint. The guide rail is made of 1.5mm galvanized steel sheet and fireproof strip. The guide rail width is 100mm. The box is formed by 0.8mm galvanized steel plate. CCC certified motor and electric control box.
Component: There is no misalignment in the assembly and splicing of each component. The welding is firm, the appearance is flat, and there is no phenomenon such as slag leakage welding and looseness .etc
Performance and turbulence: The rotation of the adjacent roller shutters is flexible after swinging, swinging 90° without falling off, and the two ends of the baffle or the tamper-proof mechanism are assembled. When the roller shutter is running, the adjacent roller shutter turbulence is ≤ 2mm.
Running noise: Average noise of on/off operation <72DB.
Two-stpe shutdown: After receiving the alarm signal, the control box controls the fire shutter to automatically stop to the neutral position. After the delay is 5s~60s, it will continue to close until it is fully closed. Or the control box is connected to the first alarm signal, and then the fire shutter will be automatically closed to the middle. The bit stops, and after the second alarm signal, it continues to close to fully closed.
Fire resistance: F3<3.00h, the cotton pad is not ignited, the original probe cannot pass through, and the flame on the back surface does not appear for more than 10s.
Temperature controlled release: It is equipped with a temperature-controlled release device. When the temperature around the temperature sensing element of the release device reaches 73′C+0. 5′C, the release device acts, and the roller shutter is closed by its own weight. Mineal fibre compositus fire resistant shutter has only temperature controlled release performance.
