It's a completely valid concern! Rust is the enemy of any metal product left outside. The good news is that high-quality metal urban planter boxes are specifically engineered to handle the elements. Ours are treated with durable, weather-resistant finishes to ensure they last for years.
The primary defense is a high-grade powder coating. This isn't like ordinary paint; it's a dry powder electrostatically applied and then heat-cured, forming a hard, uniform shield that is highly resistant to chipping, fading, and, most importantly, moisture. For added protection in critical areas, some planters use galvanized steel bases or frames. The galvanization process coats the steel in a layer of zinc, providing sacrificial corrosion resistance.
For ultimate peace of mind, we recommend placing your planter in a well-drained location and using a liner with drainage holes. This prevents soil and standing water from constantly contacting the metal. With this simple care, you can enjoy the sleek, modern look of metal in your garden, on your patio, or balcony without worrying about unsightly rust. Our planters are designed to be as tough as they are stylish.
