S355J2+N steel sheets are non-alloy structural steels manufactured in accordance with EN 10025-2. They are supplied in the normalized or normalized rolled (+N) condition. With a minimum yield strength of 355 MPa and guaranteed impact toughness at -20 °C, they are widely used in heavy steel construction, industrial fabrication and mechanical engineering. They provide excellent structural performance and long-term reliability, even in demanding applications.
Sidastico supplies cut-to-size S355J2+N steel sheets in a wide range of thicknesses and dimensions. This service meets the needs of steel fabricators, engineering companies and industrial manufacturers. Precision cutting delivers material ready for fabrication, reduces waste and improves production efficiency. Every delivery includes EN 10204 3.1 certification, ensuring full material traceability and compliance with European quality standards.
S355J2+N steel sheets offer excellent weldability, good machinability and high mechanical strength. They are suitable for laser cutting, oxy-fuel cutting, bending, drilling, punching and welding. These properties make them ideal for bridges, steel structures, industrial plants, cranes, earthmoving equipment, energy facilities, machine frames and heavy-duty structural components. They also perform reliably in applications exposed to high mechanical loads.
With extensive stock availability and advanced steel processing capabilities, Sidastico ensures fast delivery, consistent quality and dependable service. Cut-to-size processing helps optimise production and reduces additional machining. S355J2+N steel sheets are the preferred choice for applications requiring high strength, certified toughness and reliable long-term performance.
