About us

Corten A, Corten B as the symbol of weathering steel material, weathering resistant steel or atmospheric corrosion resisting steel. Even, some people called all the weathering steel as Corten Steel.

Shanghai Royal Industry has been committed to the of export steel industry more than 10 years, located in International city--shanghai, where is not only the Chinese economical center, but also the National steel trading certer. weathering resistant steel is our most advantage product.
