需要考虑电动卷帘门的尺寸和材料。根据安装位置和门洞尺寸选择合适的门型号。门的材料通常有铝合金、不锈钢和钢材等，不同材料具有不同的特点，如耐腐蚀、坚固和美观等，选择时要考虑具体的使用环境和外观要求。

We need to consider the size and material of the electric roller shutter door. Choose the appropriate door model based on the installation location and door opening size. The materials used for doors usually include aluminum alloy, stainless steel, and steel. Different materials have different characteristics, such as corrosion resistance, sturdiness, and aesthetics. When selecting, specific usage environments and appearance requirements should be considered.

要考虑电动卷帘门的使用频率和承载能力。根据门的使用频率确定合适的电机功率和型号。使用频率较高的门需要选择功率较大的电机，以确保门的开启和关闭速度适中且稳定。同时，要根据门的尺寸和材料来计算门承载能力，确保电机能够顺利工作并且门的开关不会超过其承载能力。

Consider the frequency of use and load-bearing capacity of electric roller shutter doors. Determine the appropriate motor power and model based on the frequency of use of the door. High frequency doors require selecting motors with higher power to ensure moderate and stable opening and closing speeds. At the same time, the bearing capacity of the door should be calculated based on its size and material to ensure that the motor can work smoothly and the opening and closing of the door will not exceed its bearing capacity.

要考虑电动卷帘门的性能。选择具有防盗和防火等功能的电动卷帘门，可以提高门的性能。防盗门通常配备防护装置、警报器和电子锁等，可以有效预防和抵御破坏和入侵。防火门则具有耐高温、耐火和防烟等特性，可以在火灾时提供有效的防护。

Consider the safety performance of electric roller shutter doors. Choosing an electric roller shutter door with anti-theft and fire prevention functions can improve the safety performance of the door. Anti theft doors are usually equipped with protective devices, alarms, and electronic locks, which can effectively prevent and resist damage and intrusion. Fire doors have characteristics such as high temperature resistance, fire resistance, and smoke prevention, which can provide effective protection in the event of a fire.

还要考虑使用方便性和智能化程度。选择能够通过遥控、手机APP或智能家居系统等方式操作的电动卷帘门，可以提高使用的便捷性和舒适度。此外，一些智能化的电动卷帘门还具有定时开关、遥控监控和远程控制等功能，可以满足不同的需求和场景。

We also need to consider the convenience of use and the level of intelligence. Choosing an electric roller shutter door that can be operated through remote control, mobile app, or smart home system can improve the convenience and comfort of use. In addition, some intelligent electric roller shutter doors also have functions such as timing switch, remote monitoring, and remote control, which can meet different needs and scenarios.

要考虑服务和售后支持。选择有良好信誉和售后服务的电动卷帘门厂家，可以确保产品质量和售后保障。在选择电动卷帘门型号时，可以参考其他用户的评价和案例，了解厂家的产品质量和服务水平。

Consider service and after-sales support. Choosing an electric roller shutter door manufacturer with good reputation and after-sales service can ensure product quality and after-sales support. When choosing an electric roller shutter door model, you can refer to the evaluations and cases of other users to understand the manufacturer's product quality and service level.
