Indaten® 355HD
Indaten® 355HD introduction
Indaten® 355H meets the requirements of the reference standard and has been further optimised to give extremely high processing and in-service performance.
When used uncoated and exposed to bad weather, an oxide layer develops on the steel surface, forming a purplish-brown, finely grained patina that bonds very strongly to the steel and protects it. With their characteristic colour, steels with improved atmospheric corrosion resistance are used in architectural projects either to harmonise with the environment or to create a pleasing contrast with other materials, such as stainless steel. If the patina is damaged, the steel re-oxidises, thus repairing the patina and maintaining the protective barrier.
Steel with improved atmospheric corrosion resistance can also be coated (paint, metallic coatings etc).
Experience has shown that organic coatings adhere better to this steel than to other steel grades.
