With a one-inch raised base and sizes ranging from 19 to 23 inches high, our Corten Steel rectangular planter can enhance any indoor or outdoor design.
Choose to have drainage holes, so plants stay healthy in this metal planter. For indoor use, drainage isn’t necessary. However, it’s important to note that these metal planters are ideal for outdoor conditions. Made from thick-gauge fully seam-welded Corten Steel, also known as weathering steel, it arrives in a raw steel state and rusts to a beautiful patina.
Proven to resist weather-related issues, including hot and cold extremes, our Corten Steel rectangular planter will look beautiful in both the winter and summer months.
