CORTEN steel is made up of a group of steel alloy materials which when left uncoated and exposed to the natural elements develops a very distinguishable rust patina. Originally developed for its high tensile strength, its unique look and finish has made it a popular aesthetically as a building material chosen by architects and builders Australia wide. Despite the corrosion on the surface of CORTEN Steel, the material still contains twice the tensile strength to that of mild steel making it an ideal structural building material as well.
CORTEN is commonly used as an external cladding system for large and small, private and public buildings. This generally, is a purely aesthetic application of the Corten material.
