EN 10025-5 S235J2W Corten Steel

S235J2W is a weathering (atmospheric corrosion resistant) structural steel grade supplied to EN 10025-5. It combines a guaranteed minimum yield strength of 235 MPa at ambient temperature with improved resistance to atmospheric corrosion, making it suitable for exposed structural applications where reduced maintenance and prolonged life without painting are desired.

Key specifications

• Standard: EN 10025-5
• Grade: S235J2W (weathering steel / Corten-type behaviour)
• Thickness range: 3 – 150 mm
• Width range: 1,220 – 4,200 mm
• Length range: 5,000 – 18,000 mm
• Mechanical requirement: minimum yield strength 235 MPa; impact energy ≥ 27 J at −20 °C
• Typical delivery condition: normalized-rolled or as-rolled

Principal features and benefits

• Improved atmospheric corrosion resistance compared with ordinary structural steels — forms a protective oxide layer (patina) in outdoor environments
• Good weldability and formability typical of S235-class steels
• Available in wide size ranges to suit large structural sections or plate-fabrication work

Typical applications

• Bridges, viaducts and steel pedestrian structures
• Building façades and architectural cladding where patina finish is acceptable
• Outdoor storage tanks, silos, agricultural and landscaping equipment
• Heavy structures and components exposed to the elements where reduced coating maintenance is required

Supply and ordering

• Supplied to meet EN 10025-5 chemical and mechanical requirements; inspection certificates can be provided on request
• Available to order in full plate sizes or cut-to-size; additional processing (flame/plasma cutting, beveling, shot-blasting, edge preparation) can be quoted per RFQ
• Packaging and export crating options available for sea or road freight

If you require a formal quote, please provide required plate sizes, thickness, quantities, delivery terms and any required testing or certification (e.g., EN 10204 3.1).
