Living near the coast offers beautiful views but poses a significant challenge for metal outdoor furniture due to salt-laden air, which accelerates corrosion. Preventing rust requires a proactive approach starting with material selection. Opt for inherently rust-resistant metals like aluminum, stainless steel (grade 304 or preferably 316 for marine environments), or galvanized steel. For existing furniture, the first line of defense is a high-quality protective coating. Thoroughly clean and sand the surface to remove any existing rust, then apply a rust-inhibitive primer followed by a durable exterior-grade paint or a clear marine varnish designed for metal. Powder coating is an excellent, durable factory-applied option for new pieces. Regular maintenance is crucial in a coastal urban setting. Rinse your furniture weekly with fresh water to remove salt deposits. Dry it thoroughly, especially in joints and crevices. Inspect coatings biannually for chips or scratches and touch them up immediately to prevent moisture from reaching the bare metal. Use fitted covers made from breathable fabric to shield furniture from salt spray and rain when not in use. Additionally, consider strategic placement—position furniture under eaves or pergolas to minimize direct exposure to sea breezes and morning dew. By combining the right materials, robust protective barriers, and consistent care, you can significantly extend the life and appearance of your metal urban outdoor furniture despite the harsh coastal environment.
