Six major problems in the use of fireproof rolling shutter door

<p><a href="https://www.zhtdoors.com/fireproof-shutter" rel="noopener noreferrer" target="_blank">Fireproof rolling shutter door</a> is a kind of fireproof and heat insulation facility suitable for large openings of buildings. The product has played a certain role in the design and installation of technology. Fireproof rolling shutter doors are widely used in the fireproof partitions of industrial and civil buildings, which can effectively prevent the spread of fire and protect the safety of life and property. It is an indispensable fireproof facility in modern buildings. So what kind of problems does the roller shutter door industry have to be strengthened? The following is an analysis of the six major problems of the rolling door industry organized by China and Thailand. Let's take a look.</p><p><br></p><p>First, the thickness of the fire curtain door:</p><p>Curtain thickness problem The thickness of the curtain is the thickness of the steel plate used in the curtain plate. At present, there is a phenomenon of cutting corners. Some manufacturers use thicker steel plate for the test. After obtaining the certificate, they use a thinner one for production. Because the thickness of the curtain plate at the installation site is not easy to measure, and it is easy to get through, there are many fire-resistant rolling doors that fail to meet the requirements due to the thickness of the curtain, reducing the service life and fire resistance time limit.</p><p><br></p><p>Second, the structural problems of the lintel of the fireproof rolling door:</p><p>The structure of the door lintel must be equipped with a door lintel structure according to the national standard fire shutter door. At present, fireproof rolling shutter door without a door lintel are commonly used. This kind of door cannot prevent the strong impact of the fire upward when a fire occurs. Causes smoke to spread out through the door lintel. The sealing of the door lintel is the key to fire prevention and smoke prevention. If a fireproof rolling door without a door lintel structure is installed, it will not really play a role in fire prevention and is useless.</p><p><br></p><p>Third, the problem of guide rails for fireproof rolling shutter door</p><p>The problem of the guide rail is that the depth of the guide rail is not enough, and the inappropriate structure and materials are the common problems in the installation of many large-scale roller shutter doors. Generally, there should be a main component that can withstand high strength on the guide rails of large-scale rolling doors. However, many manufacturers use simple and lightweight guide rails instead. In the event of a fire, the door curtains can easily fall out of the guide rails, which does not prevent fire.</p><p><br></p><p>Fourth, the bottom curtain problem of fireproof rolling shutter door</p><p>The bottom beam problem of the roller shutter door. Some products do not have a bottom beam. Some products have a bottom beam, but the materials are thin. The bottom beam of the curtain is an important component to maintain the strength of the curtain. If there is no bottom beam under the curtain, it is equivalent to a frame with a strong function at the lower part of the curtain.</p><p><br></p><p>Fifth, the strength of the fireproof rolling door transmission device</p><p>The strength of the transmission device of the fireproof roller shutter shaft is also an important parameter of the roller shutter door. At present, there are many products with unqualified strength, which seriously affect the use of the fire roller shutter door. The structure of the roller blind shaft mainly refers to the depth and structure of the shaft ends of the roller blind shaft plugged into the steel pipe. The plug depth of the shaft head should be about 1/10 of the shaft length, and there must be two flanges and sufficient welds. Some manufacturers' products are very short, and even use a flange. This cut-off door may break after a period of use.</p><p><br></p><p>Sixth, the transmission problem of manual control of fireproof rolling shutter door</p><p>The transmission problem of the manual quick closing device when the power is off is in fire. In the event of a power interruption, on-site personnel may use a manual quick release device. Close the door. Some fireproof rolling shutter door are not equipped with this device. Even if it is installed, it often does not work due to quality problems.</p>
