Coastal seating is constantly exposed to harsh saltwater environments, leading to rapid corrosion and deterioration. To combat this, selecting the right materials is crucial. Stainless steel (grade 316 or higher), marine-grade aluminum, and powder-coated metals are excellent choices due to their rust-resistant properties. Applying protective coatings like epoxy or polyurethane can further shield surfaces from saltwater damage. Regular maintenance, including rinsing with fresh water and applying wax or sealants, helps prolong the lifespan of coastal furniture. Additionally, using UV-resistant and waterproof fabrics for cushions prevents degradation. For long-term solutions, consider modular designs that allow easy replacement of corroded parts. By combining these strategies, coastal seating can remain durable and aesthetically pleasing despite the challenging marine environment.
