The Corten Steel from Idealist is a beautiful, low maintenance outdoor planter. The steel is designed to "weather" or "age" to give a coppery colour that will improve with time. Starting out as a blue/grey colour, as soon as Corten Steel is exposed to the elements, it will naturally weather and develop a rich eye catching finish.
This natural fixed coating of rust provides protection against further corrosion. After the initial reactive period, Corten Steel will cure and self-seal with little to no carbon run off.
During the weathering process the Corten Steel produces carbon run off which can stain adjacent materials such as stone or concrete. Please note this product will start its dense chemical composition once received, at any point and throughout the weathering process.
