You are absolutely right to ask about rust resistance near the ocean. Salt spray is brutal on ordinary steel, and even “weatherproof” coatings can fail within a season. In our factory, we do not rely on paint or sealing tricks. For benches destined for coastal parks, boardwalks, and seaside restaurants, we use two special metals: marine-grade 316L stainless steel for all fasteners, brackets, and joints, and either cast aluminum or 6061-T6 aluminum with a heavy-duty powder coat for the frame and slats. The aluminum itself contains no iron, so it cannot produce rust oxides. The 316L grade adds molybdenum, which gives it exceptional pitting resistance in chloride-rich air. We also avoid any crevices where saltwater can pool, and we use closed-cell gaskets where metal meets metal. Every weld is argon-purged and passivated to remove surface contamination that could start corrosion. The result is a bench you can hose down once a year and still look new after a decade of oceanfront sun, wind, and salt fog. If you want, we can send you a sample coupon of our exact metal sandwich and demonstrate the salt-spray test results. This is not a coating promise — it is metallurgical certainty. Choose our benches and you will not spend your weekends scrubbing rust streaks or repainting supports. Instead, you will simply enjoy the view.
