Indaten® 355D
Indaten® 355D introduction
Indaten® 355D is a steel with improved resistance to atmospheric corrosion that meets the requirements of the EN 10025-5:2004 standard. This grade is fine-grain, high-strength structural steel that has been optimised to give improved processing and in-service performance.
With its characteristic colour, Indaten® 355D steel is used in architectural projects either to harmonise with the environment or to create a pleasing contrast with other materials, such as stainless steel. 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. If the patina is damaged, the steel re-oxidises, thus repairing the patina and maintaining the protective barrier. Indaten® 355 can also be coated (paint, metallic coatings etc). In the case of coated parts, the protective layer prevents rust propagation under the paint layer.
Experience has shown that the adhesion of organic coatings on Indaten® 355A is superior to bonding on other carbon steel grades.
