Flexible door is a super door used under extremely complex working conditions, mainly used in harsh environments such as shipyards, docks, hangars, sandblasting rooms, etc. Flexible doors can be customized according to different door opening shapes, including ordinary and convex shapes!

Flexible doors should meet the requirements of wind resistance and safety performance, and their wind resistance performance should not be lower than level 12 wind. The safety performance should be equipped with anti fall devices, opening and closing alarm devices, and point switches as standard. The above performance should not be lower than the requirements of the national standard GB/T 7106-2019 for building doors and windows!
