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 700 MPa.

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 of prEN 10219 (2016) 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 12-18 meters, 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.
