(2) in the guideway inspection, the parallelism error and vertical degree error of the majority of manufacturers are not met with the standard requirements, resulting in the large gap between the middle gaps and the fire and smoke prevention measures.

(3) plate, some manufacturers of fire shutter can't contact with the ground, in the event of fire, the fire from between the plate and the ground, by the fire place spread to other parts, cannot effectively prevent spread of fire smoke, not fire separation effect.

(4) there is no drawing production in the production enterprises of fireproof rolling curtain. In order to save the business, most of the enterprises according to the size of the door, the site assembly and installation, do not draw the drawing, resulting in the installation quality low.
