Strenx® Section 650MC
General Product Description
Strenx® Section 650MC is a cold-formed steel section made of hot-rolled, high-strength steel with a minimum yield strength of 650 MPa.
Its high-strength combined with naturally stiff form enables construction of stronger and lighter structures. Typical applications include demanding load-bearing structures in the lifting, handling and transportation segments.
Strenx® Section 650MC is available as U-section. Other shapes and variations are available upon request. The maximum length of the sections is 21 meters, cut-to-length sections are available upon request.

The mechanical properties are tested in the longitudinal direction.
1) If ReH is not applicable then Rp0.2 is used. On thicknesses >8 mm the minimum yield strength may be 20 MPa lower.
