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.
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.
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.
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.
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.
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.
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.
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.
