Corten Steel Grades


Corten Steel Grades

Corten steels are special alloy steels that offer high resistance to atmospheric conditions. Over time, they form a protective oxide layer on the surface, which prevents further corrosion. This natural protection allows long service life without the need for painting.


Corten Steel Grades According to EN Standards

S355J0WP (1.8945)

  • Corten steel grade compliant with European standards

  • High resistance to atmospheric corrosion

  • Suitable for architectural façades, bridges, and outdoor structures

  • Medium to high mechanical strength

S355J2WP (1.8946)

  • Improved low-temperature impact resistance compared to S355J0WP

  • More suitable for cold climate conditions

  • Preferred for long-lasting façades and load-bearing structural systems


Corten Steel Grades According to ASTM Standards

ASTM A588

  • The most commonly used Corten steel grade

  • High strength and excellent corrosion resistance

  • Widely used in bridges, steel constructions, and industrial structures

ASTM A242

  • Lower strength compared to A588

  • Suitable for thin-section architectural and decorative applications

  • Aesthetic appearance is the main advantage

ASTM A606

  • Available in thin sheet and coil form

  • Used for façade cladding and architectural panels

  • Excellent formability


Corten Steel Applications

  • Architectural façade cladding

  • Landscaping and decorative applications

  • Bridges and steel construction structures

  • Artistic and industrial designs
