General Product Description

Strenx® Tube 700MLH is an HF-welded cold-formed structural hollow section made of hot-rolled high-strength steel with a minimum yield strength of 101 ksi.

Its high strength combined with naturally stiff form of welded hollow section enables construction of stronger and lighter structures. Strenx® Tube 700MLH meets or exceeds the requirements o EN 10219-3 (2020) and it is CE marked according to EN 1090-2. Typical applications include load-bearing structures in the lifting, handling and transportation segments, especiallyin conditions that require extremely good toughness.

Strenx® Tube 700MLH is available in circular, square and rectangular shapes. Other shapes and sizes are available upon request.

The maximum length of the tubes is 472.440"- 708.660", depending on the size. Longer or cut-to-length tubes are available upon request.

Hot dip galvanizing Strenx® Tube 700MLH hollow sections maylead to cracking. Please consult SSAB Tech Support prior galvanization.

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).
