Whether you're building an industrial building, agricultural equipment, bridge, multistore facility, crane or other load-bearing structure, you’ll be building a strong foundation with SSAB hollow structural sections – while slashing the structure’s weight, saving on materials and costs, and innovating your designs for the future.
Contact us Product overviewGet more strength with less steel. Cold-formed, welded structural hollow sections (SHS) with high strength-to-weight ratios give you exceptional structural support. Choose from round, square or rectangular hollow tubes in the broadest range of sizes and thicknesses to fit your needs, with value-added properties available.
SSAB Domex® Tubes give you high-strength hollow sections in an unbeatable combination of wide dimensional range, batch-to-batch consistency and customization potential. We can deliver the tube you need, whether it's mild steel or high-strength 550MH. Our double-grade hollow sections are specially designed for construction purposes, combining steel grades S420MH and S355J2H.

With its superior cleanliness and fine-grain microstructure, SSAB Boron Tube allows for critical forming operations, such as punching, shearing, and stamping – in as-rolled condition – with minimized risk of microcracking. Quenching in oil or in water-polymer solutions works equally well, with the latter providing additional environmental benefits. SSAB Boron steel minimizes or eliminates the need for tempering after quenching, reducing energy costs and manufacturing time.
Looking for lightweight, long-span and load-bearing in your structural applications? SSAB’s hollow sections can bring you cost and weight savings in bridge and building trusses, especially in a hybrid truss design combining mild and high-strength steels.
You can also now take advantage of the excellent properties of products in the SSAB Domex® Tube offering in imperial dimensions. Download the imperial dimensions chart for SSAB Domex® Tube Double Grade structural hollow sections.
What is the environmental impact of structural hollow sections throughout the whole lifecycle? You can find this out in SSAB’s environmental product declarations, EPDs.
Get your hands on our free handbooks! Our handbooks on hollow sections provide in-depth theoretical information and step-by-step methods for efficient and optimized building design in accordance to the EN1993 Euro code. We also have the most comprehensive existing structural hollow section handbook on how to utilize high strength steels of up to 700MPa.
With our design tool, creating new designs quickly and accurately just got easier. FrameCalc is a fast and easy software program for designing trusses made of hollow sections. This tool is free of charge and so simple to use.
Join our experts and learn more about SSAB’s tubular steel offering with our online training. You’ll also get on-demand access to recorded webinars and more information about tubular products in a downloadable format.
First transmission line made from SSAB Weathering steel was installed from Ylitornio to Liakka over ten years ago. Line is 57 kilometers long and has 222 poles and it is owned by TLS Verkko OY. SSAB delivered SSAB Weathering steel tubes to the project and VK-Electric built the line for TLS Verkko Oy.
A new research center and office will be built at SSAB Europe Oy Raahe mill. The new two-story research center and office building is scheduled to be in use in 2024. In connection with the project, a new pneumatic pipe bridge will be built. The mail pipe will transport samples from the smelter and blast furnace to the new research center. About six kilometers of the new pneumatic mail pipe will be built and the old one will be upgraded. Work on construction of the pneumatic mail pipe foundation and workshop connecting the research center and the mill began in 2022 and will complete this spring.
SSAB delivered around 200 tons of structural hollow sections to its customer STH Steel for the steel frame of Snellman’s new warehouse. New warehouse will be 40x60 meters and transportation will drive under the warehouse expansion to the slaughterhouse.
SSAB has released a new version of FrameCalc optimization tool where the solver is completely new. SSAB has also released new design tool FrameFEM convenient for more detailed analysis of tubular structures. Both of the applications in FrameX family are provided with web-based user interface designed for enhanced ease of use.
