Description:
Aluminum Spiral High Speed Doors. A model of Rapid Doors with thermal insulated aluminum slats. 
Most advanced and high-oriented model. It is fit for areas with high demand of both security, high-strength, thermal ins-
ulation and high running speed.

Features:
1. High speed opening and closing
The running speed can reach 2m/s, 10 times as traditional roller shutter door. This obviously improves passing efficiency
through it and enhances overall output.
2. High-strength
The door slat is very thick double aluminum slat, with good strength. It can protect inside goods or property by preventi-
ng theft or robbers. And the door can resist big wind pressure up to 120km/s wind speed, namely Wind Scale 12 class.
3. Good thermal-insulation
Double skin aluminum alloy slats , inside is filled with high-density insulating rock wool . Total Thickness of door panel:
43mm; With excellent thermal insulation performance. It can prevent thermal loss of the cold room and save energy
4. Excellent safety performance 
Dual protection design. Every door is equipped with safety photo sensor and proximity sensor, avoiding collision accidents
and protecting passing human or vehicles. 
5. High frequency operation
The operation frequency can reach more than 1000 times per day without any faults. This meets need of heavy traffic in
some areas.

Applications:
All kinds of Factories, Warehouses, Packaging industry, Chemical industry, Machinery industry,Loading bays.
