Fast opening and closing Running speed comparation: Sectional door: 0.3m/s; Traditional roller shutter door: 0.06-0.08m/s; So, sectional doors are four times the speed of a traditional roller shutter door. It opens and closed much faster. This bring several big benefits: • Improve work efficiency: Workers or forklifts will no need wait long time in front of the door. The material handling speed is higher by at least 3 times than traditional roll up doors; • Keep clean and hygiene: The fast running reduces the open time to only seconds in a cycle of passing the door. Thus much less outside air and dust will enter the room; • Keep temperature: Heat loss is reduced by large by reducing open time.
