Door structure
The door frame is made of high-quality galvanized steel plate, and the surface is sprayed with plastic. Or made of aluminum alloy. (When the door is 3000*3000, the wind resistance level is about 6, and the wider the door is, the worse the wind resistance effect is);
Driving device
According to the needs of customers to choose different motors: Germany imported SEW three-phase asynchronous motor, domestic SEJ three-phase asynchronous motor, domestic servo motor, etc. This series of motor features large load, high efficiency, strong braking force, long service life and so on.
Electronic control system
According to the needs of customers to choose different motors: Germany imported SEW three-phase asynchronous motor, domestic SEJ three-phase asynchronous motor, domestic servo motor, etc. This series of motor features large load, high efficiency, strong braking force, long service life and so on.
Opening and closing speed
Advanced opening and closing buffer design: when the door body opens and closes, the door body runs to about 20CM from the upper and lower limits to perform deceleration buffer action, this function can make the door body stop smoothly, but also reduce the wear of the transmission components to a minimum, especially the brake pad of the electromagnetic brake motor, effectively prolong the service life, and can be more accurate parking positioning. Adjustable rise/fall acceleration function, 0.6-1.2m opening speed per second (adjustable), so that the fast door in the opening and closing of stable operation, low noise, reliable performance, longer service life of parts; High frequency turn on (1000-1500 times/day).
Safety device
(1) The bottom of the curtain is equipped with aluminum alloy bottom beam and EPDM air bag rubber strip, the door in the process of falling and slight collision with the object will make the door body stop and rise in reverse. A pair of external Korean Ottonix grating protection switches are installed at the lower part of the door frame. When people and objects stay below the door body to block the grating rays, the door body will not fall.

Rapid rolling door product introduction:
I. Technical requirements and instructions
1. Fast rolling shutter door is a door curtain made of color high strength chemical fiber soft waterproof cloth and configured with horizontal reinforced components. It can roll up and down quickly.
1), door curtain with high strength coating fabric PVC curtain, curtain thickness 1.0㎜, color is double dark blue, with a transparent window in the middle;
2) The curtain fabric has the characteristics of cold resistance, low temperature resistance, not easy to wear and aging;
3), door curtain, tensile strength (N / 30 ㎜) : 2100 ~ 2500 N, tear strength 280 N or more.
2, the door curtain has the effect of closing the hole. It can be divided into three types according to the materials used:
1) Translucent door curtain -- coated with high strength polyester fabric as the base material;
2), opaque curtain, made of polyethylene resin materials;
3), with window curtain - in the opaque curtain opening, sewing visual window.

3. Track
The track is made of 2.0㎜ thick aluminum alloy. Surface electrostatic powder spraying white gray; Orbit inside and outside with a brush seal, guarantee between architecture and door seal, dust, insects.
