is the European standard specifying the technical delivery conditions for weldable structural steel plates used in the fabrication of fixed offshore structures. It provides a rigorous framework for high-strength steels designed to withstand the harsh environmental conditions typical of the North Sea and similar offshore sectors. Scope and Application
Once you have studied the , you need to talk to steel mills like ArcelorMittal, Dillinger, or SSAB. Do not simply ask for "EN 10225-1 steel." You must specify the full designation. en 10225-1 pdf
Offshore structures often use heavy plates where stress is applied perpendicular to the surface. This can lead to lamellar tearing. The standard defines requirements for "Z-quality" (Z25, Z35), ensuring the steel has high ductility through its thickness, preventing catastrophic failure in critical nodes and joints. EN 10225-1:2019 is the European standard specifying the
