Product Introduction:

Steel composite fire and smoke curtain

The D-type curtain plate is composed of the main curtain plate and the auxiliary plate, and the hollow is filled with non-combustible insulating refractory protection material (no water curtain protection is required). Therefore, the steel composite roller curtain has strong rigidity, long fire resistance time and radiation heat on the back. Greatly reduced etc. superiority. The appearance of the curtain plate is smooth, beautiful and comfortable, equipped with electric and manual double-function devices. The product has been tested by the state, and the fire resistance time is more than 3 hours, and its performance and quality have reached the national standards. Therefore, this product has been selected by famous buildings in the country.

Technical performance

According to the national standard GB14102-93 judgment

Conditions: Fire resistance time is more than 3 hours, without loss of integrity.

According to the test results of GB7107, the air permeability is less than 0.2 cubic meters /minm.

Strength test shows: wind pressure 120kg/m2

Opening and closing speed: up 3-5m/min, down 5-6/min.

Average noise: less than 60db.

Materials:

(1) The various raw materials used in the main parts of the fire shutter meet the provisions of the corresponding national standards or industry standards.

2. The thickness of ordinary curtain plate is greater than or equal to 0.8MM.

3. The thickness of the seat plate is greater than or equal to 3.0MM.

Curtain Board:

1. The steel fire-proof smoke curtain adjacent to the curtain plate is connected in series and rotates flexibly, swinging 90 degrees, and does not fall off.

2. The baffle plate at both ends of the steel fire and smoke prevention roller shutter or the anti-channeling mechanism should be firmly assembled, and the momentum of the rolling shutter is not more than 2MM when the rolling shutter is running.

3. The curtain plate of the steel fire-proof smoke curtain is straight, and no holes or gaps are allowed after assembling the curtain.

Performance characteristics:

1. It is a new generation of products, which does not need water curtain protection, composed of two curtains inside and outside, and filled with fire insulation materials in the middle.

2. The curtain plate is made of hot-rolled galvanized sheet, which has novel shape, smooth and beautiful inside and outside, strong rigidity, good sealing and stable fire resistance.

3. With electric and manual opening and closing dual functions.

4. Both with smoke, temperature alarm system linkage, in case of fire can achieve automatic control, can also be achieved by the fire central control room total control.

1. Technical performance and advantages: The application of advanced patented technology combines the dual functions of fire door and fire rolling curtain into one, realizing the functions of synchronous rolling, sealing, opening to the evacuation direction and self-closing of the safety door in the curtain, which is convenient for the safe evacuation of personnel and fire fighting.

2, the maximum flexibility to use the building interior space beautify the environment.

3. The safety door in the rolling curtain can be flexible. The position can be on both sides or in the middle; Two safety doors can be arranged in the same rolling curtain, and the safety size can be variable to meet the needs of various construction sites.

4. Technical parameters

1) Safety door opening force < 120N

2) Safety door opening Angle ≥85°

3) Safety door size ≥1.75m width ≥0.70m(can also be increased according to user needs, up to 2m high and 1m wide)

Fire resistance 240min did not lose integrity, 240min thermal radiation intensity 0.41w/cm 2, did not lose heat insulation.
