Many cases show that the quality of the rolling shutter door has shrunk, which is related to the unqualified design and composition materials of the rolling shutter door. In this regard, based on the current situation, I would like to briefly introduce the matters needing attention in the process of design, installation and use.

Design matters of rolling shutter door
1¡¢ÔÚ²»Ê¹ÓÃÕýѹËÍ·çϵͳµÄÂ¥ÌݼäÉè¼Æ¹Ø±ÕÂ¥ÌݼäºÍ¾íÁ±ÃÅʱ£¬±ÜÃâÑÌÎí½øÈëÂ¥Ìݼ䣬¿ÉÒÔ°ü¹ÜÂ¥ÌݼäµÄ·ÀÑÌЧ¹û¡£
1. When the stairwell without positive pressure air supply system is designed to close the stairwell and rolling shutter door, smoke can be prevented from entering the stairwell, which can ensure the smoke prevention effect of the stairwell.

2. When designing the positive pressure air supply system for the rolling shutter door of the staircase and its front room, the open area of a single fan shall be considered to match the positive pressure air supply volume. If the opening area is too large, in case of fire, the opening may not be smooth enough due to the influence of wind pressure during the operation of the positive pressure air supply system in the staircase, which is not conducive to the rapid evacuation of personnel.

3. As the normally open type has the function of automatically closing through the electromagnetic release valve or magnetic suction door, door closer and automatic control system, it can automatically close quickly in case of fire, so as to prevent the spread of fire and smoke. The design not only facilitates evacuation in case of fire, but also avoids damage caused by frequent use.

1. To prevent the normally closed roller shutter door set in the front room of evacuation corridor, smoke proof staircase or shared front room from being opened normally and becoming a "normally open" roller shutter door. "Open" roll up blinds cannot stop smoke and fire.

3. Eliminate the one-sided pursuit of decorative effect of the unit, cancel the door frame of the rolling shutter door, only set the door pocket made of ordinary wood, replace the original door leaf frame with other materials, and paint the decorative surface layer on a large area, thus damaging the fire-proof coating. No fire protection effect.

4. Jinan rolling shutter door factory suggests that we should regularly test the normally open rolling shutter door, check whether its self closing control system, door closer, sequencer, release switch, etc. are convenient to use, and whether it can effectively close the function in case of fire, and at the same time, we should resolutely prevent random stacking of goods near the normally open Jinan rolling shutter door.
