Hollow sections


For efficient manufacturing & unlimited freedom of design

Structural hollow sections

SSAB produces cold-formed and welded structural hollow sections for multiple purposes, ranging from versatile SSAB Domex Tubes to ultra-high-strength Strenx Tubes. Whether you are building lifting or moving equipment or designing buildings, you can find a suitable product to best fit your needs. With SSAB's structural hollow sections, you can significantly reduce the weight of your steel structures while gaining savings in material and manufacturing costs – without limiting the freedom of design.

Strenx Tubes are the most advanced high-strength hollow sections in the market. They will help you reach higher, carry bigger loads, reach longer spans or improve your products in many other ways.

SSAB Domex Tubes provide an unbeatable combination of higher load capacity, wide dimensional range and tailoring possibilities. SSAB Domex Tube Double Grade is especially designed for construction purposes, combining steel grades S420MH and S355J2H.

SSAB Weathering Tube family makes possible to achieve advanced engineering and construction under tough atmospheric conditions. Use of SSAB Weathering Tubes mimimize the need for maintenance and corrosion preventation treatments.

Strenx tubes

Strenx Tubes

Strenx is the most advanced high-strength structural steel in the world. The naturally stiff tubular shapes help you get the most out of the strength. Strenx Tubes are available with steel grades S700 up to S960.

Typical applications for Strenx Tubes are lifting equipment, material handling, frame structures, lattice structures as well as trusses and columns. They are easily weldable and available in various shapes and sizes, including customer-specific shapes.

SSAB Domex Tubes

SSAB Domex Tubes is a product family of versatile, high strength hollow sections with numerous tailoring possibilities and benefits. They fulfill or exceed the requirements of EN 10219 and are available with steel grades S235 to S550.

SSAB Domex Tube Double Grade hollow sections are especially designed for steel construction according to EC3 and EN 1090. They have an improved buckling curve, thickness tolerance and impact toughness guarantee.

With SSAB Domex Tubes you can benefit from the low alloying, dimensional accuracy and batch-to-batch consistency to get savings on design desk and on the workshop floor.

Lighter and more cost efficient trusses with hybrid design

Lighter and more cost efficient trusses with hybrid design

SSAB has a unique offering of standard and high strength hollow sections suitable to be used in steel construction, especially in trusses. Traditionally only mild steels, S355 and even lower, have been used in construction, but SSAB has shown that cost and weight savings can be achieved in trusses with high strength steels, especially by using hybrid design.
