The Conc Corten Steel Tapered Cylinder starts as blue steel and transforms into a warm rust finish when exposed to the elements. This fixed rust layer protects the steel from further corrosion, ensuring durability. Ideal for indoor or outdoor use, it features drainage holes, frost and UV resistance, and a textured surface. The reactive period may cause rust runoff, but the material self-seals over time, offering low-maintenance beauty. Perfect for eco-conscious landscaping, its robust construction complements a variety of settings.
