Living by the coast offers beautiful views and fresh ocean breezes, but that salt air can wreak havoc on outdoor furniture. When selecting benches for your coastal town, park, or property, choosing the right materials is crucial for longevity and minimal maintenance. The constant exposure to salt spray creates a highly corrosive environment that quickly deteriorates unsuitable materials.
For maximum durability in coastal locations, marine-grade stainless steel (particularly 316 grade) stands as the premier choice. This alloy contains molybdenum, which provides exceptional resistance to saltwater corrosion. While more expensive initially, its decades-long lifespan makes it cost-effective over time. Aluminum benches, especially powder-coated varieties, offer another excellent solution. The powder coating creates a protective barrier that prevents salt from reaching the metal substrate. Look for aluminum specifically rated for marine environments.
When wood is preferred for its natural aesthetic, tropical hardwoods like teak, ipe, or shorea naturally resist moisture and insects. These dense woods contain oils that protect against salt damage. For other wood types, ensure they're properly sealed with marine-grade sealants and maintain regular resealing schedules. Avoid plain steel or iron benches, as they'll quickly rust despite protective coatings. Similarly, standard stainless steel (304 grade) will eventually succumb to pitting and corrosion in harsh coastal conditions.
Plastic and recycled plastic lumber benches provide maintenance-free alternatives that won't corrode, though they may fade from UV exposure over time. Whatever material you choose, proper installation that avoids moisture traps and allows for air circulation will extend your benches' lifespan. With the right selection, your coastal benches can remain beautiful and functional for years despite the challenging salt air environment.
