1) the scope of application: the logistics channel, indoor cut off, the gate diameter within an area of50 square meters of inside and outside the door, since heat, dust, noise reduction, every taste, the role of high-efficiency, the greatest scope of application of 4500mm × 4500mm. 2) Frame Material: common: cold-rolled steel plate (2.0mm thick cold rolled steel baking process). 3)Materials: high-density industrial fabric. Thickness: 0.8mm Color: yellow, blue, white, orange, gray, or transparent 4) the performance of wind pressure:equipped with aluminum alloy curtain rod 5) opening and closing speed: (0.8-1.5m / s), can open the high-frequency high-frequency open (800-1000) times / day 6) protection devices: rapid volume at the bottom of the door posts with optoelectronic devices, in the course of the closure hit obstacles, declined to immediately stop rebound. Another optional airbag device to increase the safety factor. 7) The sealing performance: at the bottom end of pocket with PVC increase may be in close connection with a variety of uneven ground. Posts on both sides with brush seals to reduce noise and increase the sealing effect. 8) Drive: Germany import SEW motor single-phase 220v power 0.75-1.5KW powerful motor brake-exclusive worm gear reducer all-in-one. 9) electronic control system: 1, control box for the five keys (on, stop, next, power instructions, automatic switching) for the three gate-controlled lateral rise, stop, drop switch. 10) Open method: manual push-button (basic configuration), remote control-type, cord-type, photoelectric type, radar type, and magnetic induction (optional configuration)
