Cor-Ten pH treated

Weathering steel, best-known under the trademark COR-TEN steel, is a steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. "Weathering" means that due to their chemical compositions, these steels exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather. Weathering steel is popularly used in outdoor sculptures, such as in the large Chicago Picasso sculpture, and as exterior facades, for its rustic antique appearance. The oxidation's stabilization period takes from 12 to 16 months, but for this finishes we adopted a special treatement with acceleration natural oxidation and then fixing the oxidation at an intermediate stage to get this beautiful dark brown.
