Due to the steels high strength, structures can be designed lighter, payloads increased, and energy used more efficiently. In Europe the structural steel specification EN 10025 includes a range of high strength quenched and tempered steel grades and the designation S690QL gives the parameters for steel with a minimum yield strength of 690 MPa.
