Reasons for unstable installation of hard fast doors

In the installation and use of hard fast doors, there are often some common problems and malfunctions. A common issue is unstable installation. Let´s take a look at the reasons for the instability caused by the fast door manufacturer.


This is closely related to the technical level of the construction personnel. Whether a hard fast door can be used well depends on the installation quality. Due to different installation teams, the quality level also varies. Even some installation teams may transfer some installation personnel from other places to catch up with the project schedule. These personnel are not dedicated personnel, which can cause unstable installation quality.


The motor and electrical control system are important for the fast and frequent opening of hard fast doors. When selecting, they must be suitable for hard fast shutter speeds. If chosen improperly, it will lead to instability.


The turbine lifting mechanism is also an important technology in this system. Firstly, it depends on whether the turbine is a dual turbine lifting mechanism to ensure the safety and effectiveness of the lifting method; Secondly, it depends on whether it is a metal material, because according to material analysis, if plastic materials are used, once small cracks appear, the entire door will become paralyzed, and the severity of the entire door will decrease. Then, if nylon materials are used once water enters, it cannot be discharged. If this product is used in the north, it is dangerous. Once it reaches the freezing point, it will freeze the entire structure.


In fact, the reason why hard fast doors are popular is because they have the advantages of strong wind resistance and fast speed. Therefore, when selecting and installing, the door panel with a broken bridge design should be selected to meet the requirements of uniform strength and appearance of the door panel, which is more conducive to long-term use and effectiveness.
