General Product Description

SSAB Domex Tube Double Grade is structural hollow section.

It meets or exceeds the requirements of standard EN 10219 and includes two separate modern steel grades: S355J2H and S420MH. The choice of grade depends on the customer's or designer's application and requirements.

When your main goal is excellent usability or simplicity of design, grade S355 presents the best choice. If you are looking for considerable weight reduction and longer spans, consider selecting grade S420MH.

Welding and other workshop instructions and regulations like welding procedure test (ISO 15614-1), material classification (ISO 15608), welding qualification (EN 287-1; ISO 9606-1) and EN 1090 certification procedure must follow the appropriate steel grade S355 or S420 selected.

Welding in corner areas is always permitted when using SSAB steels.

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.
