 High speed running

The opening speed can reaches up to 2.0m/s. And the closing speed can reaches up to 1.0m/s. This means that the door can finish a cycle of opening and closing within in 

several seconds. It bring several major benefits:

Improve work efficiency:  

Workers or forklifts will no need wait in front of the door and can directly go across it. The material handling speed is higher by at least 5 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.

Thermal insulated and high strength

The door slat is made from double skin aluminum sheet filled with high density PU foam. Total thickness reaches 43mm. 

Good thermal insulation:  

Special cold-bridge design, cutting off the heat transmission route. It can help keep temperature inside the room;

High wind-resistance: 

benefiting from its aluminum material and reinforcing curving design, the door can windstand wind up to 120km/h; 

Safety protection: 

it can prevent outside people and protect the warehouse from theft and robbery.

Longer work life with lower maintenance   

Advanced Italy servo technology drive motor and control system. Compared  with traditional door system in the market, it has several advantages:

Double encoders:  

They calibrate with each other, to make running limit more accurate than tradtional limit sensors. This completely avoid running limits error and reduce maintenance. And even if one encoder is damaged, you can switch to another encoder and the door will continue to work well, no need repair;

Absolute encoder: 

outside encoder is advanced absolute encoder. It will always keep the set limits even during power failure. So you no need bother to do the frequent job of re-seting the limits;

Flexile Torque Control System:  

The output torque of motor keeps changing according to running speed and load automaticlaly. This avoid over-heating and over-load after long time use, and make sure the door

work longer life.        

Various Colors 

We supply six different colors for your choice. You can make a free selection among them. Our doors can integrate into your whole building design and make the building harmony and beautiful. 

①Grey, ② Red, ③ Orange, ④ Champagne, 

⑤ Yellow, ⑥ White, ⑦ Blue, ⑧ Silver, ⑨ Coffee

Transparent windows can be made at human eye height. Its material is polycarbonate window with ultroviolet sunlight-resist. This makes it easy to see what is happening at

another side of the door. It will be more safe for a busy area with moving workers and forklifts or other vehicles. 

Various shape to fit your project site 

In some cases, you may find it difficult to install a standard spiral door in your area. The ceiling is not high enough, or there are some objects like water pipe or cable tubes passing by.  There is not enough head rom to place the top body. To solve this problem, we expand the design of guide rails, and offer three options. 

Standard spiral: 

Archimedes spiral, first choice, for enough top space;

Oval spiral:  

for limited space but above 500mm space

Low-lintel rail: 

for very limited top space less than 500mm;
