Corten is a very popular steel due to the materials rustic and
aesthetically pleasing appearance. It is a weather resistant steel
which reacts to natural elements in the atmosphere and forms its
own protective layer of rust. This layer continues to replenish
itself over time and therefore the steel does not usually require
any form of external treatment.
The steel is used in a variety of applications, both structural and
cosmetic, including bridge construction, structural framework and
building facias.
