济南卷帘门由于结构简单，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，因此无论在工作中还是生活中，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。有人觉得卷帘门无非是早上开一次晚上关一次，需要什么技术含量，能出什么大问题？好，那么今天我就一次性将这些问题说个清楚。

Because of its simple structure and easy retraction and release, Jinan roller shutter doors are suitable for installation in private garages and shopping malls with limited space, as well as in large-span and super-high industrial plants. Therefore, the roller shutter doors can be seen everywhere in work and life. There are many products, and the quality is easy to be mixed. Some people think that the rolling shutter door is nothing more than opening it once in the morning and closing it once in the evening. What technical content does it need and what major problems can it cause? OK, so I will make these questions clear at one time today.

低频启闭的使用场景

Use scenario of 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 use scenarios that open once in the morning and close once in the evening, such as street shops, electric, remote control and speed, we need not pay too much attention. What we need to pay attention to is anti-theft, thermal insulation and switch smoothness.

高强度

high strength

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。

Since anti-theft is required, the strength of the curtain should be high first, so that it will not be easily damaged by violence. The common S235 steel plate in the market is not strong enough. It needs S550 steel plate, which is more than twice the strength. It is easy to deal with general damage.

可锁闭

Lockable

其次，要能锁闭，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。单靠卷帘门自身的结构重力锁闭还不够，建议是额外配备一道机械锁，确保万无一失。

Secondly, we should be able to lock, especially some shops and other civil places, once stolen, it will cause certain economic losses. It is not enough to rely solely on the structural gravity locking of the rolling shutter door itself. It is recommended that an additional mechanical lock be equipped to ensure the safety.

保温性

Thermal insulation

隆冬的寒冷、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10mm以内，内部简单穿插些岩棉条而已。好的卷帘门厚度在20mm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3.8W/m2.K。无论冬天还是夏天都可以省下一笔不菲的暖气空调费用。

The cold in the middle of winter and the hot in the middle of summer are the tests of door insulation. Most of the rolling shutter doors on the market use single-layer steel plates, even if they are double-layer, the thickness is mostly within 10mm, and some rock wool strips are simply inserted inside. The thickness of a good roller shutter door is about 20 mm, and the interior is filled with uniform and dense polyurethane foam thermal insulation material, and the thermal insulation coefficient can reach 3.8 W/m2. K. No matter in winter or summer, you can save a lot of heating and air conditioning costs.

从帘板的形状上看，流线型设计比直线型更合理，因为弧形帘板条卷绕在一起时可以更加自然紧凑，相较于直线型截面帘板，不仅减少了边角位置对帘板表面的摩擦，而且帘卷体积更小，所需的顶部安装空间更小。更多相关内容就来我们网站http://www.jnzxmy.com进行咨询了解！

From the shape of the curtain panel, the streamlined design is more reasonable than the straight type, because the curved curtain Flat noodles can be more natural and compact when rolled together. Compared with the straight section curtain panel, it not only reduces the friction between the edge and corner positions on the surface of the curtain panel, but also reduces the volume of the curtain roll and requires less top installation space.
