The range of steel grades under the **EN 10219-1** standard—from the dependable **S235JRH** through the versatile **S355JOH/JEH** to the high-performance **S460MH**—provides the essential material solution for every deep foundation challenge. This European standard guarantees not only high **Mechanical Properties** (Yield Strength up to 460 MPa) but also critical **Impact Toughness** ($\text{J0}/\text{J2}$) and superior **Weldability** through strict control of the **Carbon Equivalent**.
