Living near the coast offers stunning views and a refreshing breeze, but it also presents a unique challenge for outdoor furniture: salt air corrosion. If you’ve asked, “Does your outdoor bench factory use any special treatments to prevent rust or corrosion from salt air?”—the answer is a definitive yes. Our factory, located in a coastal region, has developed a comprehensive approach to ensure our benches withstand the harshest marine environments.
First, we prioritize material selection. We use marine-grade 6061 aluminum and 316 stainless steel for all structural components. These alloys contain chromium and molybdenum, which form a passive oxide layer that resists salt-induced pitting and crevice corrosion. Unlike standard steel or iron, they do not rust even when exposed to constant salt spray.
Second, every bench undergoes a multi-step finishing process. After welding and fabrication, we clean the surfaces with a chemical bath to remove oils and contaminants. Then, we apply a zinc-rich primer followed by a durable polyester powder coating. This coating is cured at high temperatures, creating a tough, non-porous barrier that seals out moisture and salt particles. For extra protection in high-humidity areas, we offer an optional clear ceramic coating that adds UV resistance and further prevents chalking.
Third, we design for drainage. All bench frames have slotted or angled structural elements to prevent water pooling, which accelerates corrosion. Fasteners are capped with marine-grade nylon covers to isolate them from direct salt contact. We also use sealed welds and avoid crevices where salt can accumulate.
Finally, we test every batch. Our quality control team subjects sample benches to a 1,000-hour salt spray test per ASTM B117 standards. This accelerated corrosion test simulates years of coastal exposure, ensuring our benches maintain their integrity and appearance.
Whether you place our bench on a beachfront deck or a cliffside garden, you can trust that it’s engineered to resist rust and stay beautiful for decades. We even offer a 10-year warranty against corrosion for coastal installations. So yes—we’ve thought of everything, so you don’t have to worry.
