Corten steel, also known as Weather Resistant Steel or Atmospheric Corrosion Resistant steel, is a low-cost and highly effective material.
It is classified as "self-protecting" steel due to its "patina," which results from protective surface oxidation during atmospheric exposure. This oxide layer enhances weather resistance and leads to a significantly improved service life compared to standard steels.
