Starting out as a blue steel, 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.
During the weathering process the Corten Steel produces carbon run off which can stain adjacent materials such as stone or concrete. To reduce this possible staining, all products have small feet, lifting the planter and preventing direct contact with the flooring material.
After the initial reactive period Corten Steel will cure and self-seal with little to no carbon run off. Don’t forget we offer a pre-weathering service and we can provide a bespoke service on Corten Steel so contact us if you have a special requirement!
