With the development of China's economic construction, especially with the deepening of reform and opening up and the improvement of urban modernization, the industry of intelligent door rolling machine and controller has been developing rapidly. In commercial, factory, public facilities, family and other broad areas, the intelligent roller shutter door has gradually replaced the traditional roller shutter door. As the core component of the intelligent roller shutter door, the intelligent door rolling machine and controller for the use of roller shutters have experienced constant technological upgrading. For example, the controller realizes the transition of the core components from alternating current contactor and air switch to the circuit board, chip and relay, thus realizing the portability, intelligence and electronization of the intelligent roller shutter door and controller.
At present, the intelligent door rolling machine for the use of roller shutters is mainly subdivided into two categories: the civil door rolling machine for the use of roller shutters and the fireproofing one. The civil door rolling machine for the use of roller shutters is mainly used in civil buildings, shops, garages and other occasions. Its technical content is relatively low and its technical requirements are not high. Besides, there are no industry qualification restrictions, and the application range of the product is broad. The fireproofing door rolling machine and controller for the use of roller shutters is a subdivision of the roller shutter door machine industry, mainly doing supporting work for the major manufacturers of roller shutter door. Due to the small market size and capacity, the enterprises in the field are mainly small and medium-sized private ones. In the early stage of reform and opening up, Taiwan merchants first introduced the rolling door machine into mainland, and gradually formed a certain industrial cluster in Zhangzhou, Fujian, and created a large distribution center in Renqiu, Hebei, and Fuyang, Zhejiang.
In general, the basic characteristics of the industry are the late start, short development time, limited market capacity, and generally weak competitor strength. At present, the market is still in the original and spontaneous state. Under the natural evolution of market competition, the market has formed a trend of gradual concentration. The large-scale industry integration will be inevitable in the future.
