High-strength weathering structural steel designed to provide excellent resistance to atmospheric corrosion. Thanks to alloying elements such as copper, chromium and phosphorus, it naturally develops a protective surface layer that reduces the corrosion rate and increases the service life of the component.

Brief Description
High-strength weathering structural steel designed to provide excellent resistance to atmospheric corrosion. Thanks to alloying elements such as copper, chromium and phosphorus, it naturally develops a protective surface layer that reduces the corrosion rate and increases the service life of the component.
Applications
Architectural facades, outdoor structures, bridges, metal constructions, containers, chimneys, urban furniture, infrastructure projects and applications exposed to atmospheric conditions.
