CorTen is a general name for ‘Weathering steel’; a material which forms a stable rust-like appearance after exposure to weather that was developed to be resistant to corrosion and to not need regular maintenance or painting.
Cor Ten is a mixture of different kinds of steel (alloy) and has mechanical properties that are both resistant to corrosion and very strong. The name, CorTen, is a portmanteau of “Corrosion” and “Tensile” indicating a material that is resistant to corrosion and which has a high tensile strength (resistance to breaking under tension). CorTen has excellent machinability and good weldability and formability.
During the weathering process, CorTen’s appearance changes until the surface eventually evolves into an orange, or brown, oxidised, rust-like appearance which is unique and distinctive; this stable surface eliminates the need for painting or weatherproofing so is perfect for low-maintenance applications.
CorTen is used in architectural applications and external cladding for buildings and is also popular with artists and sculptors and has been featured in many popular works of art, for example,it was used to create Antony Gormley’s ‘The Angel of the North’ in Gateshead.
CorTen steel sheet is supplied ‘un-weathered’ and will take several months to reach its stable orange brown finish, therefore, the metal you buy may well differ at first from the image shown. The weathering process is accelerated by atmospheric pollutants so weathering of CorTen will be faster in cities, urban areas, and coastal locations than out in the countryside.
