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.
