The SPA-H Corten Steel Plate is a high-phosphorus structural weathering steel designed for long-term outdoor use.
With a minimum yield strength of 350 MPa, this steel exhibits excellent resistance to atmospheric corrosion thanks to its unique chemical composition.
Exposure to weather conditions forms a protective rust layer on the surface, which continuously regenerates, protecting the steel and extending its service life.
The SPA-H Corten Steel Plate is ideal for construction, outdoor architectural projects, decorative elements, and industrial applications where durability and low maintenance are essential.
