由于卷帘门结构简单，收放自如，既适合安装在空间有限的私家车库、店铺，也适合安装在大跨度、超挑高的工业厂房。因此，不管是在工作中还是生活中，我们到处都可以看到卷帘门的身影。产品多，品质上就容易出现良莠不齐。那么，一个好的济南卷帘门是什么样子？

Due to its simple structure and easy retraction, the roller shutter door is suitable for installation in private garages and shopping malls with limited space, as well as in large-span and super high industrial factories. Therefore, whether in work or life, we can see the figure of rolling shutter doors everywhere. If there are many products, it is easy to have mixed quality. So, what does a good Jinan roller shutter door look like?

低频启闭的使用场景

Usage scenarios for low-frequency opening and closing

对于那些早上开一次晚上关一次的使用场景，如临街商铺，电动、遥控、速度这些就不用过多关注了，需要关注的是防盗性、保温性和开关的流畅性等。

For those usage scenarios that open once in the morning and close once in the evening, such as street facing shops, there is no need to pay too much attention to electric, remote control, and speed. What needs to be paid attention to is anti-theft, insulation, and smooth switching.

1.高强度

1. High strength

卷帘门的作用之一是防盗，既然要防盗，帘板的强度要高，才不于轻易被暴力破坏。市场上常见的S235钢板强度不够，需得S550硬钢钢板，强度高一倍有余，应对一般破坏自然游刃有余。

One of the functions of rolling shutter doors is anti-theft. Since anti-theft is necessary, the strength of the shutter should be high to prevent it from being easily damaged by violence. The commonly seen S235 steel plate in the market has insufficient strength, requiring S550 hard steel plate, which has more than double the strength, and can easily cope with general damage.

2.可锁闭

2. Lockable

特别是一些商铺等民用场所，一旦失窃会造成一定的经济损失。所以，卷帘门自身的结构重力锁闭，可以确保。

Especially in some civilian places such as shops, theft can cause certain economic losses. So, the gravity locking of the roller shutter door itself can ensure safety.

3.保温性

3. Thermal insulation

冬天的寒冷、盛夏的炎热都是对门保温性的考验，市面上的卷帘门多数采用单层钢板，即便是双层，厚度也多在10 mm 以内，内部简单穿插些岩棉条而已。好的卷帘门厚度在 20 mm 左右，内部填充均匀致密的聚氨酯发泡保温材料，保温系数可达3.8 W/m2.K。

The cold in winter and the hot in midsummer are both tests of door insulation. Most rolling shutter doors on the market use single-layer steel plates, even if they are double-layer, the thickness is mostly within 10 mm, and the interior is simply interspersed with some rock wool strips. A good roller shutter door has a thickness of about 20 mm and is filled with uniformly dense polyurethane foam insulation material, with a thermal insulation coefficient of up to 3.8 W/m2. K.

高频启闭的使用场景

Usage scenarios for high-frequency opening and closing

对于使用相对频繁的电动卷帘门来说，电控系统的限位准确性和保护是重要的两个方面。

For electric roller shutter doors that are relatively frequently used, the limit accuracy and safety protection of the electronic control system are two important aspects.

1.限位准确

1. Accurate limit position

电动卷帘门是在电机带动下将帘板卷绕在门轴上，如果门开到高位置，电机没有及时停住，就会将帘板从门框中强制甩出，继而发生坠落伤人危险。如果门关到低位置（地面），电机没有立即停住，而是继续带动帘板向下，帘板则会逐级向下挤压，导致门板变形，久而久之将无法正常关门。

Electric roller shutter doors are driven by a motor to wind the shutter onto the door shaft. If the door is opened to a high position and the motor does not stop in time, the shutter will be forcefully thrown out of the door frame, leading to the risk of falling and injuring people. If the door is closed to the low position (ground), the motor does not immediately stop, but continues to drive the curtain down. The curtain will gradually press down, causing the door panel to deform, and over time, it will not be able to close normally.

2.保护

2. Safety protection

卷帘门的性不容忽视，比如门帘坠落的问题，卷人、压人的问题等等。

The safety of rolling shutter doors cannot be ignored, such as the problem of falling curtains, rolling and pressing people, and so on.
