S355JO Plates

Product Overview:
S355JO Plates are structural steel plates that conform to the EN 10025-2 standard, offering a minimum yield strength of 355 MPa and excellent mechanical properties. The “JO” designation indicates that these plates are tested for impact resistance at 0°C, ensuring reliability in moderately cold environments. They are widely used in structural applications across construction, engineering, and heavy fabrication industries.
