ASTM A572 steel sheet piles are high-strength low-alloy columbium-vanadium structural steels conforming to ASTM A572/A572M standard. Available in five grades (42, 50, 55, 60, 65), they offer excellent mechanical properties including high yield strength (e.g., 345 MPa for Grade 50) and tensile strength. With good weldability and machinability, they are widely used in building, bridge, port, and marine structures like retaining walls and cofferdams, particularly Grades 50 and 60 for bridge connections.
