European Standard Structural Steel
EN 10025 : 2004
Leeco Steel offers structural steel plate that meets the European standard for structural steel, EN 10025 : 2004, in grades of: S235, S275, S355, S420, S690 & S890.
EN 10025: 2004 is the new European structural steel standard established by the European Committee for Iron and Steel Standardization. In 1990, the first EN 10025 standard was created in the UK by BSI. The next 14 years saw many revisions & additions to that standard. In 2004, the EN 10025 standard was revamped to reflect the new requirements established by the European Union’s Construction Products Directive (89/106/EEC). The EN 10025: 2004 encompasses a broader range of structural metallic products and divides them into six basic categories:
- General Purpose Steels
- Non-alloy Structural Steels
- Normalized / Normalized-Rolled Weldable Fine Grain Structural Steels
- Thermo Mechanically-Rolled Weldable Fine Grain Structural Steel
- Atmospheric Corrosion Resistant Structural Steel (“Weathering Steel”)
- High Strength, Quenched and Tempered Structural Steel
Within these six parts are individual grades. The foundation of each grade within the EN 10025 standard is the material’s tested yield strength measured in megapascals (1 MPa = 145.03 PSI). Each structural steel grade begins with an “S” and is followed by suffixes that represent variations in the specific requirement for that structural application.
Example: S355K2C+N
- “S” - structural steel
- “355” - 355 MPa / 51,486 PSI
- “K2” - Longitudinal Charpy V-notch Impact 40 J @ -20 degrees C
- “C” - Grade suitable for cold forming
- “+N” - supply condition normalized or normalized rolled
