Fast opening and closing

Running speed comparation:

Sectional door: 0.3m/s; 

Traditonal roller shutter door: 0.06-0.08m/s;

So, sectional doors are four times the speed of a tradtional 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 tradional 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.

High frequency working

There is torsion spring balance system around the drive rod. After spring tightened, it can 

balance the weight of the door body and reduce the load weight of the motor. So its drive 

motor is always in a light-load work state. This is the reason why such doors can work

continually. No need worry its motor will overload and get burnt. 

Max work frequency: 800 open-close cycles per day. 

 Flexible design to fit all project sites

The door can climb up in different ways to fit specific site situation.   

Standard lift: For limited top space, the door will turn to the ceiling directly;

High lift:  The door can climb up the wall for some distance and then turn to the ceiling; 

Vertical lift: If the ceiling is high enough, the best way is to climb up complete to the top.
