1.Material:
The door panels are made of double-layer galvanized steel and polyurethane foam.
2.Air tightness:
The industrial sectional door comes with sealing rubber strips on the bottom and sides, providing excellent air tightness when closed and improving its resilience against extreme weather like wind and sand.
3.Thermal insulation:
The polyurethane foam within the sandwich board of the industrial sectional door provides effective heat insulation, helping to minimize heat loss during winter and heat entry during summer. This is beneficial for regulating the temperature within the warehouse.
4.Safety:
Both sides of the bottom of the industrial sectional door are provided with steel wire rope breakage protectors. When the lifting steel wire rope breaks, the device can cut into the guide rail to prevent the door from falling.
5.Balance system:
The sectional door adopts torsion spring balance, which is used to balance the weight of the door body and make the balance reach the best state.
6.Low noise:
Nylon guide wheels are installed on both sides of the sectional door to ensure quiet operation while the door slides. The sturdy material of the guide wheels enables the sectional door to be used repeatedly.
