• Often called “weathering steel”, Corten steel panels form a stable rust-like appearance if exposed to the weather for several years.
  • This protective surface layer, or patina, is produced by Corten’s metal panel chemical composition and produces anti-corrosive properties superior to many other structural steels.


  • Corten steel material is highly resistant to corrosion and weather conditions, boosting durability and longevity.
  • Protective oxide layer regenerates if damaged, making it a low maintenance, cost-effective and resilient material.
  • Withstands corrosion caused by exhaust gases from sulphur-containing fuels better than many other structural steels.
  • Superior resistance to scaling at high temperatures.
  • Striking aesthetic, ideal for many sculptural and architectural applications.


  • The protective layer develops within 18–36 months under normal atmospheric conditions provided that the steel surface regularly becomes wet and dry.
  • At first, the protective layer is reddish-brown, but gains a darker hue with time.
  • In an industrial environment, the patina develops faster and becomes darker in colour than in rural areas.

Anti-corrosive Corten is a powerhouse of construction, forming a protective layer with a distinctive look and weather-resistant strength.
