To prevent corrosion and damage to aluminum profiles during transportation and storage, follow these guidelines: 1. Keep aluminum profiles dry and clean. Moisture and dirt can accelerate corrosion. 2. Use protective packaging, such as plastic wrap or padded covers, to shield profiles from physical damage and moisture. 3. Store profiles in a cool, dry place away from direct sunlight and corrosive substances. 4. Stack profiles with appropriate padding between layers to prevent scratching. 5. Avoid overloading during transportation and ensure secure fastening to prevent movement and potential damage. 6. Regularly inspect stored profiles for signs of corrosion or damage and address any issues promptly.
