Strenx® weathering steels are high-strength structural steel with yield strengths of 700 and 960 MPa. Using steel with such high yield strength levels leaves room for more high-performing designs with increased load-bearing capacity. It permits higher stresses in the structure, allowing the designer to reduce the thickness of the parts. Depending on the starting point, designers can cut up to 30 percent
of the weight off steel structures.
The special alloy composition in Strenx® weathering steel makes it perform differently than ordinary carbon steel. When exposed to alternating wet and dry weather conditions, a protective oxide layer – a patina – is formed on the steel’s surface. This oxide layer prevents further corrosion, resulting in a steel which is practically maintenance-free.
