The quality grades commonly used in shipbuilding are A, B, D, or E. These grades have similar yield strength (at least 235 N/mm²) and tensile strength (400–520 N/mm²), but differ in terms of impact toughness at different temperatures.

Our product range also includes high-strength products such as AH32, DH32, and EH32 grades, which are high-strength profiles with a minimum yield strength of 315 MPa. Additionally, the AH36, DH36, EH40, and EH36 grades offer higher strength with a yield strength of 355 MPa and are used in various maritime applications such as shipbuilding and offshore platforms.
