Weldable structural steel En 10225 for fixed offshore structures consists of carbon, silicon, manganese, sulfur, phosphorus, chromium, molybdenum, nickel, aluminum, copper, nitrogen, niobium, titanium and vanadium in the composition. GNEE is a leading manufacturer of EN 10225-3 sheets in a variety of scales and sizes.
The material has different grades, such as S355G1, S355G1+M and so on. Different grades of BS EN10225 structural steel sheet have different mechanical properties. The lowest minimum yield strength for grade S355 G1 is 355 MPa, and the highest for grade S460G4+M is 460 MPa.
