Fast rolling doors have been widely used in developed industrial countries such as Europe, America, and Japan for many years. Especially in production enterprises, there must be fast rolling doors between workshops. If it is a food or pharmaceutical enterprise, it is mandatory for the government to use fast rolling doors for isolation to prevent secondary pollution of the product. Just like our country's mandatory requirement for certain industries to install fire doors (whether you are willing or not), factories must be put into operation, and without fire doors, acceptance will not be passed, and factories cannot start construction.

　　The domestic fast rolling door industry started relatively late, but its development speed is fast, increasing by approximately 40% annually. Enterprises on a large scale are gradually becoming aware of installing fast rolling doors. One of them is indeed very helpful in improving product quality and reducing energy consumption. Secondly, it can enhance the overall image of the company.

　　1. The fast Roller shutter is only one type of Roller shutter, because Roller shutter also has many divisions. The so-called fast, that is, its running speed is relatively fast, which can exceed 0.6 meters per second, the opening speed can reach about 1.5 meters per second, and the closing speed can reach 1.6 meters per second. And it rises and falls quickly without any obstacles. As a soundproof door, its main function is to provide isolation.

　　2. The Roller shutter has the function of heat preservation or heat preservation, can resist wind and sand, and has the effect of dust prevention. More importantly, its fire and odor prevention functions are also prominent, making it widely used in food factories, textile factories, as well as refrigeration, warehousing and other places. To improve a clean environment, it is necessary to automatically shut down, improve production efficiency, and create a better working environment.
