Product details

Industrial overhead sectional doors are made from polyurethane sandwich panels. Several separate door panels are joined together into a whole body, to climb up and down directly along the wall and ceiling. This is a quite different way of opening from traditional roller shutter doors, which roll up by coiling. Automatic overhead sectional doors have several advantages compared with other types industrial use doors:

1. Excellent thermal insulation; 2. Fast running speed; 3. High frequency running; 4. Low maintenance; 5. Good wind resistance.

And its purchase price is medium and applicable for different budgets. All above factors make the overhead sectional door one of the popular industrial doors in all types of factory, warehouse, workshop, logistics, cold room, 4S Car Stores, fire stations and commercial buildings.

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.

Thermal insulated

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.

High air-tightness

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.

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.

Optional Parts:

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.
Small 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.
