1. Before materials are put into storage, rainwater or impurities should be prevented from entering. For materials exposed to rain or pollution, different methods should be used to wipe them according to their properties, such as high-hardness steel wire brushes and low-hardness cloth, cotton and other materials.
2. The materials should be checked frequently after they are put into storage. If there is corrosion, the corrosion layer should be removed.
3. Under normal circumstances, the surface of steel does not need to be oiled after cleaning, but for high-quality steel, alloy steel plate, thin-walled pipe, alloy steel pipe, etc., the inner and outer surfaces need to be coated with anti-rust oil before storage.
4. Seriously corroded steel should not be stored for a long time after derusting, and should be used as soon as possible.
