Protecting metal outdoor furniture from rust during ocean transit requires proactive measures due to the highly corrosive marine environment. The combination of salt spray, humidity, and temperature fluctuations can accelerate corrosion if furniture is improperly prepared. A comprehensive approach begins with a thorough cleaning using a mild detergent to remove any existing contaminants, followed by complete drying. Applying a high-quality protective coating is essential; for ferrous metals, use specialized rust-inhibitive primers and paints designed for marine applications, while powder coating provides excellent durability for aluminum frames. For added protection, consider applying a corrosion inhibitor like a wax-based or oil-based film that displaces moisture.

Proper packaging creates a critical barrier against salt air. Wrap each piece individually in waterproof, VCI (Vapor Corrosion Inhibitor) plastic film, which emits protective vapors. Desiccant packets should be placed inside the wrapping to control humidity. Furniture should be packed in a well-sealed, wooden crate that is elevated off the container floor to prevent contact with condensation. Strategic placement within the shipping container is also important; avoid positioning near doors where salt spray ingress is more likely, and ensure adequate ventilation to reduce moisture buildup. For maximum security, a climate-controlled container, though more costly, maintains stable temperature and humidity levels. Implementing these steps systematically significantly reduces the risk of rust, ensuring your furniture arrives in excellent condition ready for outdoor use.
