The short answer is yes—if you select the right outdoor bench materials. In a coastal city, salty air corrosion is the biggest challenge for street furniture. A cheap steel or iron bench will often rust within the first year, but a properly specified coastal street bench can hold up for a decade or more.
For a truly rust-resistant bench, 316 marine-grade stainless steel is the top choice. It is designed to resist pitting and chloride corrosion from sea spray. Powder-coated aluminum is another excellent option because aluminum is naturally corrosion-resistant, and the coating adds extra protection. High-density recycled plastic lumber won’t rust, rot, or splinter, though it may fade slightly after years of UV exposure. If you prefer wood, choose teak or another dense hardwood and expect to clean and oil it regularly.
No matter the material, pay attention to the hardware. Bolts, brackets, and legs should be stainless steel or coated with a marine-grade finish. Even the best coastal street bench needs occasional rinsing with fresh water to remove salt deposits.
So yes, a street bench can absolutely hold up well in a coastal city with salty air—but only if you choose materials and finishes that are built for salt-air corrosion. A bargain steel bench will become a maintenance headache quickly, while a marine-grade bench will sit comfortably by the water for years.
