Living near the ocean comes with beautiful views and salty breezes, but that salt air can be brutal on metal park benches. The constant exposure to salt moisture accelerates rusting, leading to deterioration that compromises both aesthetics and structural integrity. So how do we protect these vital public amenities?
The first line of defense is material selection. Opt for marine-grade metals like aluminum, stainless steel (particularly 316 grade), or galvanized steel. Aluminum naturally forms a protective oxide layer, while stainless steel contains chromium that creates an invisible rust-resistant film. Galvanized steel is coated with a zinc layer that sacrificially protects the underlying metal.
Protective coatings provide additional security. Powder coating creates a durable, uniform layer that acts as a physical barrier against salt and moisture. For existing benches, specialized marine paints formulated with rust inhibitors offer excellent protection. Regular maintenance is crucial - rinse benches weekly with fresh water to remove salt buildup, and immediately address any chips or scratches in the coating to prevent rust from starting.
Consider design elements that minimize moisture retention. Benches with slanted seats and proper drainage holes allow water to run off rather than pool. Regular inspections help catch early signs of corrosion before they become major problems. With proper material choice, protective coatings, and consistent maintenance, metal park benches can withstand harsh coastal conditions while serving communities for years to come.
