COR-TEN steel
COR-TEN is almost pure steel, slightly alloyed to form a protective patina layer in order to be resistant to all weather conditions. The patina layer initially has a reddish-brown color, becoming darker over time. In industrial or aggressive environment, patina layer forms more quickly and the color becomes darker than in cleaner rural areas. However, a protective layer of patina cannot be formed if the surface of the steel is constantly wet or dirty. COR-TEN products are supplied without patina layer.
MATERIAL
Material thickness 1.5 mm is used in Liberta & lamella products and 1.0 mm in designer profiles.
UV resistance shows how well the coating retains its original color and gloss level in accordance with EN10169. The higher the grade, the better the resistance.
The corrosion activity categories describe outdoor climatic conditions in accordance with EN12944. The higher the category, the more aggressive the environment is.
