Strenx® Tube 960MH

Show specs in Metric Imperial

General Product Description

Strenx® Tube 960MH is an HF-welded cold-formed structural hollow section made of hot-rolled high-strength steel with a minimum yield strength of 960 MPa

Its high strength combined with naturally stiff form of welded hollow section enables construction of stronger and lighter structures. Strenx® Tube 960MH meets or exceeds the requirements of EN 10219-3 (2020). Typical applications include load-bearing structures in the lifting, handling and transportation segments.

Strenx® Tube 960MH is available in circular, square and rectangular shapes. Other shapes and sizes are available upon request.

The maximum length of the tubes is 12-18 meters, depending on the size. Longer or cut-to-length tubes are available upon request.

It is not recommended to hot dip galvanize Strenx Tube 960MH hollow sections.

Dimension Range

Strenx® Tube 960MH is available at circular, square and rectangular shapes.

¹⁾ The hollow sections with D/T < 15 (round) or (B + H)/2T < 12,5 (rectangular and square), the minimum value of elongation is reduced by 2.

The mechanical properties for rectangular hollow sections are tested by SSAB on the longer side of the cross section.

Mechanical properties meet the requirements of EN 10219-3 (2020).
