    General Product Description

    Strenx® Tube 700QLH is plasma-welded, quenched and tempered hollow section with a minimum yield strength of 700 MPa.

    Its high strength, combined with naturally stiff form of the welded hollow section, enables construction of stronger and lighter structures. Strenx® Tube 700QLH meets or exceeds the requirements of prEN 10210 (2016).

    Typical applications are load-bearing lattice structures in the lifting, material handling and transportation sectors, especially in conditions where extremely good toughness is needed. 

    Dimension Range

    Strenx® Tube 700QLH is available at circular shape.
