General Product Description

SSAB Domex Tube 500MH is extra-high-strength structural hollow section.

It is available in circular, rectangular, square and special shapes. Customized shapes and other tailoring options are available upon request. It is typically used in advanced engineering and construction where weight reduction, lower costs and safety are important. It meets the standard requirements of EN 10219 when applicable and is CE marked according to EN 1090-2.

SSAB Domex Tube 500MH is manufactured by cold forming and high frequency welding from clean, high quality environmentally friendly steel by modern and efficient tube lines.

                      Mechanical properties meet or exceed the requirements of EN 10219.

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

                      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.

                      2) Impact testing according to EN ISO 148-1 is performed on thicknesses ≥ 6mm. The specified minimum value corresponds to a full-size specimen.
