Packing And Delivery

I. Packaging Procedures

Strapping: Strap I-beams with steel or nylon straps as per specifications to make handling easy.
Pallets/Dummy Boards: Use wooden pallets/dummies to place the bundles on the top to keep it away from ground and protect the coatings from scratches or dew/rain drop.

Protection:
Put corner guards or plastic sleeves on the edges and ends.
Wrap in waterproof or plastic sheets to avoid rusting from rain or moisture.

II. Methods of Transportation

Land Transport:
Perfect for local or short haul transportation.
Select rigid or articulated flat or low sided trucks where the load can be firmly banded together to avoid movement.

Rail Transport:
Appropriate for long distance bulk loads.
Observe rail transport regulations, ensure the safety of the load and use protective padding material.

Sea Transport:
For exports or cross-border transports in containers or bulk carriers.
Bundle beams and cover with waterproof tarps and stow in the hold so they will not shift.

III. Things to Remember

Do not impact or rub while loading/unloading, so as to avoid damage to the surface of the steel.

Straps and securing cans should be inspected on a regular basis over long-distance hauls.

Apply higher rust prevention treatment for moist or seaside atmosphere.

Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
