Do I need to use protective covers when storing sheet metal parts?

It is a good practice to use protective covers when storing sheet metal parts, especially in the following situations:
Prevent dust and pollution: Protective covers can effectively prevent dust, dirt, and other pollutants from entering the surface of sheet metal parts, keeping them clean.
Prevent scratches and damage: Using protective covers can prevent sheet metal parts from coming into contact with other objects, thereby reducing the risk of scratches and damage.
Corrosion prevention: In humid or corrosive environments, protective covers can provide an additional protective layer to prevent corrosion and oxidation of sheet metal parts.
Maintain appearance and quality: Using protective covers can maintain the appearance and quality of sheet metal parts, extending their service life.
When storing sheet metal parts, especially for long-term storage or in harsh environmental conditions, the use of protective covers can effectively protect the parts, ensuring that they remain clean, intact, and in good condition.
