Mostly widely used doors in all indsutrial buidlings like factory or warehouse. Thermal insulated, fast speed, high frequency running, low maintenance.
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:
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.
Door panel is sandwich structure. Total thickness: 40mm. Two surface layer
is 0.326mm galvanized steel plate. Middle is filled with high density fire
ratardant polyurethane foam. Foam Density: 12---14kg/m2.
At the joint area, there is a special cold-bridge design, to avoid direct
heat conduction through surface steel sheet.
Thermal insulation ratio: 4.5W/m. h.
For this reason, such door is widely seen in cold rooms and warehouses.
All-around of the door is covered with EPDM weather seal rubber. Such rubber can resist
cold and chemical. It can keep in good shape after years. This guarantee the high air-tightness of the whole door. It will prevent outside air and dust entering the room, and keep
inside clean and hygiene.
Flexible design to fit all project sites
The door can climb up in different ways to fit specific site situation.
You can select clear windows or man doors for your sectional door
Clear Window: People can see what is happening at another side of the door through it. This can improve safety at work place.
Man door: Fit for big size doors with a lot workers passing. This can reduce the use of whole sectional door and improve its worklife.
