Corten Steel
Corten steel (often referred to as Cor–Ten) is a weather resistant steel which could more accurately be termed as an “Atmospheric Corrosion Resistant Steel”.
It is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. It’s chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.
Aesthetically pleasing to the eye, this finish has become popular with many high profile architects and has been specified and used in a variety of applications in including building fascias, architectural sculptures and bridges.
Examples of Corten Structures
- The Angel of the North (UK)
- Matsunoyama Natural Science Museum (Japan)
- The Centre for Contemporary Art, Melbourne, Australia
The protective layer of Corten constantly develops and regenerates over time, reacting to the pollutants in the atmosphere. Consideration should be made with regard to the thicknesses used especially when the material is utilised for structural rather than solely cosmetic purposes.
The benefits of such a steel are immediately obvious – a self–protecting steel is economic, long lasting and easily recyclable.
