About Metalcorten S.L.

In the history of corten steel we have data from 1822 which states that adding copper to normal steel the resistance to corrosión was better, but it was really since the 20th century when this steel started to be investigated. In 1933, Kendal and Henderson from USS Stell started comercializing this steel under the name of Cor-ten, adding 0,03% of Copper to the chemical composition. In later years the number of tests increased until incorporating Si (silicon), P (phosphorus) and Cr (chromium) to the formula and two versions of the corten steel were developed: One with nickel called Corten A and without nickel called corten B. In EEUU test were made about the oxidation in different atmospheres. The ASTM comittee exposed different steels with copper content adn they saw that the self-skating steel could be used wihtout paint and galvanization for bridge works where a durable steel with at least 100 years of durability was needed.
