That's an excellent question! For our steel urban benches, we use a multi-layer professional finishing system specifically designed to withstand harsh outdoor conditions and prevent rust for years. The primary finish we rely on is a high-quality powder coating. This process involves electrostatically applying a dry powder to the steel surface, which is then cured under heat to form a hard, protective layer. It's superior to traditional paint because it's more durable, resistant to chipping and fading, and is available in a wide range of colors and textures. For maximum protection, especially in coastal or high-moisture areas, we often start with a hot-dip galvanized substrate. This involves immersing the steel frame in molten zinc, creating a metallurgical bond that provides sacrificial corrosion protection, meaning the zinc corrodes before the steel does. This combination—galvanization plus powder coating—offers the longest possible lifespan with minimal maintenance, ensuring our benches remain beautiful and functional in parks, streetscapes, and plazas for decades.
