门帘片：门片采用双层镀锌彩钢辊轧成型或铝合金型材，内充高密度聚胺脂发泡材料或中空，有效消除噪音，提高抗弯曲性，防止冷凝水。表面采用先进的粉末喷涂表面处理工艺，抗划伤、防腐蚀、美观大方。保温节能，安全防盗。颜色多为白色、浅灰色、棕色、古铜色等多种颜色。并可根据客户的需要制作。
Curtain piece: door panel use rolled form of double-layer galvanized color steel or aluminum alloy material, filled with high-density polyurethane foam material or hollow to eliminate noise effectively, increase the bending resistance, prevent emergence of condensate. Surface uses advanced powder coating technology, to be scratch-resistance and corrosion-resistance with an elegant appearance. Temperature-keeping and energy-saving,safety and anti-theft. Colors: white, light gray, brown, bronze and other colors. Can be produced according to customers' needs.
导轨：采用高强度铝合金型材型材，轨道两侧配有密封、降噪毛条。减少帘片与轨道之间的摩擦，并起到密封、防尘的作用。两侧配有灵活、高耐磨的尼龙导向轮，使门体运行更加轻便灵活。
Guide rail: use high-strength aluminum alloy material, on both sides with a sealed, noise-reduction top to reduce the friction between the curtain panel and the rail, and seal, dust proof. On both sides with a flexible, high wear-resistance nylon guide wheel, make the door run lighter and more flexible.
驱动装置：配有专用外置电机或内置管状电机。机械式限位定位位置可调，定位准确度小于1.5厘米。
Drive device: with special-purpose external operator or internal tubular motor. Mechanical limit position is adjustable, positioning accuracy of less than 1.5 cm.
开启方式：墙壁开关且具有自动锁死的功能，无线遥控，采用先进的编码技术，保密性强，超高感度，遥控距离特长。操作简单，使用安全。Opening way: the wall switch with auto-lock function, wireless remote control, the use of advanced coding techniques, strong security, ultra-high sensitivity, long remote control distance. Easy to operate,and safe to use.
安全保护：除电机设有自动锁死装置外，还可以加装门体在下降时如遇障碍可自动反弹装置、及红外线安全保护装置，确保人车安全。并可配备多种解决方案。
Secure protection: except the motor equipped with auto-lock device, can also install device which can be auto-rebound when the door meet obstacles in the decline, and infrared safety device to ensure the safety of people and vehicles. A variety of solutions are available.
