S690 QL Plate
S690 QL Plates are high-strength quenched and tempered structural steel plates known for excellent toughness, weldability, and load-bearing capacity. With a minimum yield strength of 690 MPa, they are ideal for applications requiring weight reduction without compromising strength—such as bridges, cranes, construction equipment, and heavy transport. These plates conform to EN 10025-6 standards and are used in both static and dynamic load-bearing structures.
