Marine Aluminum Plate 5083 H321 Packaging and Transportation

1. Packaging of 5083 H321 Aluminum Plates

Packaged using export-grade wooden crates or pallets.

Use fumigated wooden pallets with a fumigation certificate.

2. Transportation Environment Requirements

5083 H321 aluminum plates must be stored separately from active chemicals and moisture during transportation.

The transport vehicle or container must be kept dry, clean, and free of contaminants.

3. Transportation Methods

Typically transported using enclosed vehicles or containers.

For extra-long 5083 H321 aluminum plates or when using open trucks, special boxes, or containers, the cargo must be tightly covered and secured with waterproof covers to prevent water, rain, or snow from entering the packaging and aluminum products.
