Living near the ocean brings beautiful views and salty breezes, but that salt air can wreak havoc on metal benches. The constant exposure to salt spray accelerates corrosion, leading to rust, structural weakness, and unattractive appearances. So how do we protect these essential urban fixtures?
The first line of defense is material selection. Opt for inherently corrosion-resistant metals like marine-grade stainless steel (particularly 316 grade), aluminum, or galvanized steel. These materials contain alloys that naturally resist saltwater damage, significantly extending your bench's lifespan in coastal settings.
Protective coatings provide an additional barrier. Powder coating creates a durable, seamless finish that shields metal from moisture and salt. For existing benches, regular applications of specialized marine paints or rust-inhibitive primers can rejuvenate protection. Consider zinc-rich coatings that provide sacrificial protection, where the coating corrodes instead of the base metal.
Regular maintenance is crucial in marine environments. Establish a cleaning routine using fresh water to rinse off salt deposits weekly. For deeper cleaning, use mild soap solutions and soft brushes to remove corrosive buildup without damaging protective coatings. Immediately address any chips or scratches in the coating to prevent salt from reaching the bare metal underneath.
Strategic placement also matters. Whenever possible, position benches further from the immediate shoreline and provide some overhead coverage from direct rain and spray. Well-draining installations prevent water from pooling around metal components.
By combining proper material selection, protective coatings, consistent maintenance, and smart placement, your coastal benches can remain beautiful and functional for years, despite the challenging marine environment. These proactive measures ultimately save time and money while ensuring comfortable seating for everyone to enjoy the ocean views.
