URBAN OUTDOOR FURNITURE

Having specified and maintained furniture for coastal plazas, I’d say salty air is less about one killer factor and more about daily exposure: salt spray, humidity, UV, wind-driven sand, and constant wet-dry cycles. Powder-coated aluminum is usually the sweet spot for urban benches, chairs, and tables—it’s light, doesn’t rust like steel, and a good coating keeps salt away from the metal. Bare aluminum and cheap painted steel are a different story; chips and scratches become corrosion points, and regular steel hardware can start rusting within a season. For the most exposed pieces, 316 marine-grade stainless steel is the gold standard, though even it needs rinsing to prevent tea-staining and pitting. Teak handles salt well and ages to a silver-gray patina, but it can get rough and needs occasional cleaning; HDPE and high-quality resin wicker are excellent low-maintenance choices, while cheap resin can fade or crack under UV. Cushions and slings should be quick-dry, mold-resistant, and removable. The biggest real-world difference is care: a monthly fresh-water rinse, gentle soap, drying before covering, and touching up chips will add years. In a salty coastal city, I’d avoid untreated mild steel and mixed-metal fixings, choose marine-grade hardware, and expect powder-coated aluminum, 316 stainless, teak, or HDPE to hold up well—provided they’re rinsed and inspected regularly.
