Ocean shipping involves high humidity and high salt, and stainless steel can also corrode. Packaging recommendations:

- Inner layer: VCI anti-rust film or anti-rust paper, wrapping steel coils/sheets. - Desiccant: Calculate the amount based on volume and voyage length; avoid direct contact with the plate surface. - Outer layer: Wooden crate or pallet + stretch wrap; raise the bottom to prevent water accumulation. - Markings: Indicate moisture-proof, this side up, and keep away from rain. - Container: Check whether the container body leaks; lay a moisture-proof film if necessary.

Open the package and ventilate promptly after arrival to avoid long-term retention of condensation water.
