According to the open type, the rolling shutter door can be divided into manual rolling shutter and electric rolling shutter.

手动卷帘：借助卷帘轴上的扭簧平衡力量，达到手动拉动卷帘的目的。

Manual roller shutter: balance the force with the help of the torsion spring on the central shaft of the roller shutter to achieve the purpose of manually pulling the roller shutter.

电动卷帘：用专用电机带动卷帘轴转动，达到卷帘开关，当转动到电机设定的上下限位时自动停止。

Electric roller shutter: use a special motor to drive the central shaft of the roller shutter to rotate to reach the roller shutter switch. When it rotates to the upper and lower limit set by the motor, it will automatically stop.

按门片材质，卷帘门可以分为：铝合金卷帘门，水晶卷帘门，不锈钢卷帘门，彩钢板卷帘门，PVC卷帘门等。
