Introduction of Structural Steel in Europe Standard

Structural steel is a standard construction material, made from specific grades of steel and formed in a range of industry standard cross-sectional shapes (or ‘Sections’). Structural steel grades are designed with specific chemical compositions and mechanical properties formulated for particular applications.
In Europe, Structural Steel pipe must comply with the European Standard EN 10025 a Governed by the ECISS (European Committee for Iron and Steel Standardization) a subset of CEN (European Committee for Standardization.
There are many examples of European grades of structural steel such as; S195, S235, S275, S355, S420, S460 etc. However, for the purposes of this article we will focus on the Chemical Composition, Mechanical Properties and Applications of S235, S275, S355. Three common structural steel grades used in all manner of Construction projects across the EU.
Inline with the European Standard classifications, Structural steel must be referenced using standard symbols including but not limited to: "S"235"J2’‘K2’’C’’Z’’W’’JR’’JO’’
Where:
  • S – denotes the fact that it is Structural Steel
  • 235 – related to the minimum yield strength of the steel (tested at a thickness of 16mm)
  • J2 / K2 / JR / JO – material toughness in relation to the Charpy impact or ‘V’notch test methodology
  • W – Weathering Steel (Atmospheric Corrosion Resistant)
  • Z – Structural carbon steel pipe with improved strength perpendicular to the surface
  • C – Cold-formed
Depending on the manufacturing process, chemical composition and relevant application, further letters and classifications might be used to reference particular grades/products of structural steel .
