Now Jinan roller shutter door has been basically popularized, but people don't pay much attention to the maintenance of roller shutter door, which is a very bad phenomenon. Summer and autumn is the rainy season in Jinan. Special attention should be paid to rust prevention during the use of rolling shutter doors. The rusty Jinan rolling shutter doors not only look ugly, but also greatly reduce the efficiency when they are convenient to use.

金属卷帘门在日常的使用过程中，暴露在空气中，难免会风吹日晒，所以氧化的概率是很高的。

In the daily use of metal roller shutter doors, exposure to the air will inevitably lead to wind and sun, so the probability of oxidation is very high.

以前安装的旧式金属卷帘门，因为材质的关系，使用2-3年后，很容易出现门体氧化，锈蚀表面甚破坏门体结构，从而造成金属卷面门不能使用的情况。

Because of the material, the old metal rolling shutter door installed before is easy to oxidize, rust the surface and even damage the door structure after 2-3 years of use, resulting in the non use of the metal rolling shutter door.

现在这个问题已经引起了卷帘门厂家的足够重视，新出产的金属卷帘门在出厂之前，在表面都做过特殊处理，可以保证在正常使用的情况下3-5年都不会锈蚀。

Now this problem has attracted enough attention from the rolling shutter door manufacturers. The newly produced metal rolling shutter door has been specially treated on the surface before leaving the factory, which can ensure that it will not rust for 3-5 years under normal use.

所以，旧式的金属卷帘门，一旦发生氧化，就预示着门体离报废不远了。这时候可以在表面喷上一层油漆，延缓金属的氧化。

Therefore, once the old metal rolling shutter door is oxidized, it indicates that the door body is not far from scrapping. At this time, a layer of paint can be sprayed on the surface to delay the oxidation of metal.

不管是旧式的还是新式的金属卷帘门，都需要每个礼拜擦拭吸附在上面的灰尘、雨水等异物，防止金属的氧化。

Whether old or new metal roller shutter doors, they need to wipe the dust, rain and other foreign matters adsorbed on them every week to prevent metal oxidation.

另外，日常在使用过程中，要避免碰撞门体，这样会造成济南卷帘门的金属材料裸露在空气中，缩短了使用寿命。

In addition, in the process of daily use, it is necessary to avoid collision with the door body, which will cause the metal materials of Jinan roller shutter door to be exposed in the air and shorten the service life.

为了防止卷帘门生锈，我们可以定期用棉布蘸上少量的防锈油或缝纫机油擦拭卷帘门表层部分。若发现卷帘门已经开始有锈斑，那我们应该尽早用棉纱蘸机油涂于锈处，这样可以除掉锈迹，而不能直接用砂纸和其它糙面材料进行打磨。

In order to prevent the rolling shutter door from rusting, we can regularly wipe the surface part of the rolling shutter door with cotton cloth dipped in a small amount of antirust oil or sewing oil. If it is found that the rolling shutter door has begun to have rust spots, we should apply cotton yarn dipped in engine oil to the rust as soon as possible, so as to remove the rust, rather than grinding it directly with sandpaper and other rough materials.
