开店做生意的人对卷帘门都不陌生，早上一拉开门做生意，晚上一关锁门走人。但真到要装门或者换门的时候，很多人发现卷帘门种类不少，报价从几百到上千一平米都有，商家说的名词也听着差不多，到底选哪种心里没底。其实卷帘门看着简单，门道都在材质、结构和安装方式上，选错了轻则用两年就卡顿生锈，重则防盗和消防都过不了关。

People who open shops and do business are no strangers to rolling shutter doors. They open the door in the morning to do business, and close the door and leave at night. But when it comes to installing or replacing doors, many people find that there are many types of rolling shutter doors, with prices ranging from a few hundred to over a thousand square meters. The terms used by the merchants also sound similar, and they are unsure which one to choose. In fact, rolling shutter doors look simple, and the door passage depends on the material, structure, and installation method. Choosing the wrong one can cause them to freeze and rust after two years of use, and in severe cases, they cannot be closed for anti-theft and fire protection purposes.

先分清几种常见卷帘门，用途差别很大。 市面上非常常见的是普通彩钢卷帘门，帘片是彩涂钢板，价格便宜，适合对防盗和美观要求不高的仓库、车库。第二种是铝合金卷帘门，重量轻、耐腐蚀，表面可以做多种颜色，适合商铺和车库，但防盗性一般。第三种是不锈钢卷帘门，强度高、防盗好，用在金店、药店、手机店这些需要高安全性的场所。还有一种是防火卷帘门，用在商场、地下车库的防火分区，验收时是硬指标。如果拿普通卷帘门代替防火卷帘门，消防验收肯定过不去。

Firstly, distinguish several common types of rolling shutter doors, which have significant differences in their uses. The most common type on the market is ordinary color steel rolling shutter doors, with color coated steel plates as the curtains, which are cheap and suitable for warehouses and garages with low requirements for anti-theft and aesthetics. The second type is aluminum alloy rolling shutter door, which is lightweight, corrosion-resistant, and can be made in multiple colors on the surface. It is suitable for shops and garages, but its anti-theft performance is average. The third type is stainless steel rolling shutter doors, which have high strength and good anti-theft properties, and are used in places such as gold shops, pharmacies, and mobile phone stores that require high security. There is also a type of fireproof rolling shutter door, which is used in fire compartments of shopping malls and underground garages, and is a hard indicator during inspection. If ordinary rolling shutter doors are used instead of fireproof rolling shutter doors, the fire safety inspection will definitely not pass.

帘片厚度和填充物，是决定耐用度的关键。 同样叫彩钢卷帘门，帘片厚度从0.3毫米到0.6毫米都有，薄的用手一按就凹，厚的抗冲击能力强很多。有些帘片中间填充聚氨酯发泡，保温隔音效果好，但价格高一些；空心的帘片便宜，但强度差。另外，导轨的厚度和材质也影响使用寿命，导轨太薄，门体运行几年后容易脱轨或者卡死。选门的时候不能只问"多少钱一平"，要问清楚帘片厚度、导轨规格、电机品牌这些具体参数。

The thickness of the curtain and the filling material are the key factors determining durability. Also known as color steel rolling shutter doors, the thickness of the curtain varies from 0.3 millimeters to 0.6 millimeters. Thin ones can be easily pressed by hand, while thick ones have much stronger impact resistance. Some curtains are filled with polyurethane foam in the middle, which has good insulation and sound insulation effects, but the price is higher; Hollow curtains are cheap, but their strength is poor. In addition, the thickness and material of the guide rail also affect its service life. If the guide rail is too thin, the door body is prone to derailment or jamming after several years of operation. When choosing a door, you can't just ask "how much does it cost per square meter", you need to clarify specific parameters such as curtain thickness, guide rail specifications, and motor brand.

电机和控制系统，决定每天开关门顺不顺心。 电动卷帘门的核心是电机，电机功率不够，门体稍微大一点就带不动，或者用一段时间后越来越慢。好的电机有过载保护、限位调节、遇阻反弹这些功能，门体碰到障碍物能自动停下，安全性高。控制系统方面，遥控器、墙壁开关、停电时的应急手动装置都要配齐。商铺用的话，还要考虑每天开关频繁，电机的耐用性和售后维修是否方便。济南本地有实体店的商家，电机出问题能上门修，比网购自己找人装省心。

The motor and control system determine whether the opening and closing of the door goes smoothly every day. The core of an electric rolling shutter door is the motor. If the motor power is not enough, the door body may become too large to move or slow down after a period of use. A good motor has functions such as overload protection, limit adjustment, and rebound when encountering obstacles. The door can automatically stop when encountering obstacles, ensuring high safety. In terms of control system, remote controllers, wall switches, and emergency manual devices for power outages must be fully equipped. If you use it in a shop, you also need to consider frequent daily switching, the durability of the motor, and the convenience of after-sales maintenance. Local businesses with physical stores in Jinan can come to their homes to repair motor problems, which is more convenient than finding someone to install them online.

安装和售后，比门本身还重要。 卷帘门是"三分产品七分安装"，导轨装得不垂直，门体运行起来就歪，用不了多久就卡。门洞的尺寸测量、预埋件的处理、电源线路的预留，这些安装环节做不好，再好的门也用不住。选商家时要看有没有专业的安装队伍，质保期多久，保修范围包含哪些。卷帘门是天天用的东西，出了问题能及时上门维修，比当初便宜那几百块钱重要得多。

Installation and after-sales service are more important than the door itself. Roller shutter doors are "three parts product and seven parts installation". If the guide rails are not installed vertically, the door body will tilt when running, and it will get stuck in a short time. The measurement of the size of the door opening, the handling of embedded parts, and the reservation of power lines cannot be done well, and even the best doors cannot be used. When choosing a merchant, you should consider whether there is a professional installation team, how long the warranty period is, and what the warranty scope includes. Rolling shutter doors are something we use every day, and it's much more important to have them repaired in a timely manner if there's a problem, compared to the few hundred yuan they were originally cheaper.

济南卷帘门市场选择多，但不同材质、不同配置的门差别不小。把用途、材质、电机、安装售后这几件事弄清楚，才能选到既耐用又省心的门。

There are many choices in the Jinan rolling shutter door market, but there are significant differences in door materials and configurations. Only by understanding the purpose, material, motor, installation, and after-sales service can one choose a door that is both durable and worry free.
