To prevent rust on aluminum profiles during storage and transportation, follow these guidelines: 1. Keep aluminum profiles dry and clean, avoiding contact with moisture or corrosive substances. 2. Store profiles in a cool, dry place, away from direct sunlight and heat sources. 3. Use protective packaging materials to shield profiles from physical damage and moisture. 4. Apply a protective coating or sealant to the aluminum surface if it's exposed to harsh environments. 5. Regularly inspect stored profiles for signs of corrosion and address any issues promptly. By adhering to these practices, you can minimize the risk of rust formation on aluminum profiles during storage and transportation.
