1. Manual, electric function (all open within 30 seconds), windproof, rainproof and good sealing;

2. Fast and convenient manual operation; good insulation performance; strong ability to resist high winds;

3. Lightweight switch with low noise; takes up less space;

4. Applicability:According to the design of the building structure, the lift door opens vertically upwards and hangs on the inside of the wall above the door opening without occupying any space in the room; it takes full advantage of the vertical rise and does not occupy the sides of the door opening to release the door opening space to a large extent;

5. Appearance: Double-layer galvanized steel plate with polyurethane layer, the surface embossing design can make the door panel durable, easy to clean, beautiful and generous, and enhance the corporate image;

6. Thermal insulation performance: Double-layer steel plate reduces thermal energy loss, with high-density polyurethane 48kg / m3 thermal insulation layer inside, which has excellent thermal insulation effect.

7. noise isolation: Low noise opening. The galvanized pulley seat is equipped with adjustable ball bearings and wear-resistant rubber wheels to ensure that the door opens and closes silently.

8. Wind resistance: When the door body reaches a certain width, external stiffeners are designed to ensure its strength. Tested by European standards, it can withstand instantaneous level 10 wind.

9. Air tightness: The top, bottom and both sides of the door panel are equipped with high-quality rubber sealing strips. There are also reliable seals between the door panels to ensure that the door body is not subject to erosion. All sides are equipped with sealing strips, which has excellent air tightness.

10. Safety device: Anti-fall device and airbag (optional) prevent the door from automatically stopping or reverse running when the door body falls or the bottom of the door collides with an obstacle to prevent accidents; anti-wire rope break device and torsion spring break safety device.
