市面做济南卷帘门的商家有很多，各种材料型号应有尽有，作为一个对卷帘门没有过深入研究的小白来说想从鱼龙混杂的市场上选择一款称心如意的卷帘门更是难上加难，其实卷帘门能不能长期使用看这几点就足够了。

There are many manufacturers of Jinan roller shutter doors in the market, and all kinds of materials and models are available. As Xiaobai, who has not studied roller shutter doors in depth, it is more difficult to choose a satisfactory roller shutter door from the mixed market. In fact, it is enough to see whether the roller shutter door can be used for a long time.

1、电动卷帘门是否支持手动功能，手动要方便，快捷。停电时将离合扭转90度，即可手推运行。

1. Whether the electric roller shutter door supports the manual function, which should be convenient and fast. Turn the clutch 90 degrees in case of power failure, and then push it manually.

2、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。

2. The electric roller shutter door shall have the function of double side automatic locking instead of inertial sliding.

3、为了提高电动卷帘门运行平稳程度，要增强拉力，所以本厂采用的是8轮前后驱动，连排齿轮转动的生产安装技术。

3. In order to improve the smooth operation of the electric roller shutter door and enhance the tension, the factory adopts the production and installation technology of 8-wheel front and rear drive and continuous row gear rotation.

4、观察电动卷帘门的结构是否精细，润滑程度好坏，好的电动卷帘门散热比较，采用全齿轮转动，无链条、无皮带，进而增强了卷帘门机芯整体寿命。

4. Observe whether the structure of the electric roller shutter door is fine, whether the lubrication degree is good or not, and compare the heat dissipation of the good electric roller shutter door. The full gear rotation is adopted, without chain and belt, thus enhancing the overall life of the roller shutter door movement.

此外不同种类的卷帘门会有一些不同的功能，我们根据自己的应用情境来进行选择，比如如果想要应用在商铺，可以选择水晶卷帘门，更加美观，而且吸引人们的关注。如果是需要有效隔绝内外环境，我们可以选择封闭式卷帘门。

In addition, different types of roller shutter doors have different functions. We can choose them according to our own application situations. For example, if you want to apply them to shops, you can choose crystal roller shutter doors, which are more beautiful and attract people's attention. If it is necessary to effectively isolate the internal and external environment, we can choose the closed roller shutter door.

总之，根据自己的需求选择更有针对性的卷帘门。另外，卷帘门有手动、电动之分。如果想要购买电动卷帘门的小伙伴可以特别关注一下其有无手动功能，一旦遇到电动功能故障，我们还可以使用手动，比较方便。

In a word, choose a more targeted rolling shutter door according to your needs. In addition, there are manual and electric rolling shutter doors. If you want to buy an electric roller shutter door, you can pay special attention to whether it has a manual function. In case of an electric function failure, we can also use the manual function, which is more convenient.
