Corten, a material originally developed in the 1930’s by the United States Steel Corporation, was once primarily used for railway coal wagons. This new material was in high demand thanks to its inherent toughness and ability to withstand weather conditions, which are possible due to the controlled corrosion that makes Corten unique.
The features of robustness and improved resistance to corrosion that make Corten such a popular choice for specification is possible thanks to the careful manipulation of the alloying elements added to the steel during the production process, and works by reducing the carbon content of the material to therefore give it a higher capacity for carrying load.
One of the most beneficial properties of Corten is it’s high level of weather resistance. Read more in our recent article on ‘Corten’ as a rainscreen cladding material.
