Default thickness limits have increased in the 2019 version: Steel Grade Type Maximum Thickness (mm) MLO Grades (S355–S500) QLO Grades (S420–S690) Key Changes in the 2019 Edition

Before you download a , you must understand what this document represents. EN 10225 is a European standard titled: "Weldable structural steels for fixed offshore structures – Technical delivery conditions." 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.
