Packing and Transportation

Packaging
UPN steel profiles are typically bundled and packaged to ensure safe handling, storage, and transportation. Proper packaging protects the steel from mechanical damage, corrosion, and deformation during transit. Common packaging methods include:

Bundling:
- Profiles are grouped into bundles of standard lengths.
- Steel strapping (metal or plastic) is used to secure bundles.
- Wooden blocks or spacers may be placed between layers to prevent scratching.
End Protection:
- Plastic caps or wooden end covers protect the edges and corners of the UPN profiles.
Surface Protection:
- A thin layer of rust-preventive oil can be applied for long-term storage or overseas shipment.
- In some cases, profiles are wrapped in waterproof packaging or coated with protective film.

Transportation
Proper transportation is critical to maintain the integrity of UPN steel profiles. Common practices include:

By Sea (Overseas Shipment):
- Bundled profiles are loaded onto flat racks, containers, or open-deck vessels.
- Bundles are securely fastened to prevent shifting during transit.
