S690QL High Strength Steels & Construction steels
S690QL High Strength steel
S690QL is a quenched and tempered steel for structural applications (trailers, machinery, agricultural applications).
The high mechanical strength (min. 690 N/mm²) allows significant weight savings compared to conventionnal structural steels.
