Corten Steel


Corten steel, also known as korten, is a steel with a rusty appearance that has very aesthetic qualities and is being increasingly used in design. It is found particularly in building (architecture and construction), in public spaces (street furniture) or to make upmarket works of art, signs, chimineas and fire bowls. Is corten steel expensive? Yes, it is. Corten is significantly more expensive than other common grades of steel. Corten steel planters are easily 50%-100% more expensive than a similarly sized planter of another long-lasting material.


Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.The combination and production of these alloys means corten steel is a weatherproof, strong and corrosion resistant material known for having a brown-orange appearance.
