Coastal metal sculptures face relentless exposure to saltwater, which accelerates corrosion and compromises their longevity. To protect these artworks, follow these best practices:

1. Material Selection: Opt for corrosion-resistant metals like stainless steel, bronze, or galvanized steel. These materials inherently withstand harsh marine environments.

2. Protective Coatings: Apply high-quality anti-corrosion coatings such as epoxy, polyurethane, or powder coatings. Regular reapplication ensures ongoing protection.

3. Design Considerations: Avoid crevices and traps where saltwater can accumulate. Smooth, sloping surfaces help water runoff and reduce corrosion risks.

4. Regular Maintenance: Rinse sculptures with fresh water frequently to remove salt deposits. Inspect for early signs of rust and address them promptly.

5. Sacrificial Anodes: Use zinc or magnesium anodes to divert corrosion away from the sculpture, a technique often employed in marine applications.

By combining these strategies, artists and conservators can significantly extend the life of coastal metal sculptures, preserving their beauty despite the challenges of saltwater exposure.
