Corten steel planter is a type of planter made from corten steel, which is a special alloy steel with good weathering and corrosion resistance. These planters are often used in outdoor environments such as gardens, decks, or patios as they are resistant to sun, rain, and oxidation, and are less likely to rust or corrode, making them more durable and long-lasting. At Gnee Garden, our corten steel planters usually have a modern and minimalist design that matches various outdoor décor styles, making them ideal for landscaping and planting.
