卷帘门这么受欢迎，我们如何去选购合适的卷帘门呢？现在大家使用的卷帘门几乎都是自动的，很少人还会去选择纯手动的。那小编给大家总结了三点，只要注意到这三点，就可以选到合适自己使用的卷帘门。

Roller shutter doors are so popular, how can we choose the right roller shutter door? Now the roller shutter doors used by everyone are almost automatic, and few people will choose pure manual. The editor summarized three points for you. As long as you pay attention to these three points, you can choose a roller shutter door that is suitable for your own use.

1.支持手动

1. Support manual operation

观察卷帘门是否支持手动功能，支持的话要看手动是否方便快捷。为什么支持手动？万一在出现故障或者停电问题的时候，电动卷帘门还没有手动功能，那门怎么关？你不可能就把门开一晚上。

Observe whether the roller shutter door supports the manual function. If so, see whether the manual operation is convenient and fast. Why is manual supported? In case of failure or power failure, how can the electric roller shutter door be closed if it has no manual function? You can't leave the door open all night.

2.运行平稳

2. Stable operation

选择卷帘门，要观察期卷帘门的运行是否平稳。电动卷帘门不能存在惯性滑行的现象，要具有双面自动卡锁功能，这样才可以让卷帘门平稳运行。

When selecting the roller shutter door, observe whether the operation of the roller shutter door is stable. The electric roller shutter door shall not have the phenomenon of inertial sliding. It shall have the double-sided automatic locking function, so that the roller shutter door can operate smoothly.

3.结构精密

3. Precise structure

我们在选择卷帘门的时候，需要去观察电动卷帘门的结构是否精密，润滑程度是否良好，散热是否正常，是否采用全齿轮转动，是否有链条、皮带等。这些如果全部是良好的，卷帘门的寿命肯定是比较长的。

When we select the roller shutter door, we need to observe whether the structure of the electric roller shutter door is precise, whether the lubrication is good, whether the heat dissipation is normal, whether the whole gear is used for rotation, and whether there are chains and belts. If all of these are good, the service life of the roller shutter door must be relatively long.
