Coastal sculptures face relentless exposure to saltwater, which accelerates corrosion and deteriorates their aesthetic and structural integrity. To combat this, selecting corrosion-resistant materials like stainless steel, bronze, or marine-grade aluminum is crucial. These metals inherently withstand harsh marine conditions better than traditional materials.

Applying specialized anti-corrosion coatings, such as epoxy or polyurethane sealants, creates a protective barrier against saltwater penetration. Regular maintenance, including rinsing with fresh water and inspecting for early signs of rust, can significantly extend the sculpture's lifespan.

For added protection, consider galvanization or sacrificial anode systems, which divert corrosive forces away from the sculpture. Proper placement—elevating sculptures to avoid direct wave impact—also reduces saltwater exposure. By combining these strategies, artists and conservators can ensure coastal sculptures remain vibrant and durable for generations.
