Hollow sections – build a stronger future with less steel
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.
SSAB structural hollow sections
Get 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
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.

SSAB Boron 24 Tubes
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.
High-strength hollow sections for stronger, lighter steel trusses
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.
SSAB Domex® Tube also available in imperial dimensions
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.

Superior weldability and produced-to-length deliveries from mill – When highest quality and production efficiency are required
SSAB delivers structural hollow sections to the frame structures of Best-Hall’s buildings. One of the recent projects was Duodot. SSAB delivered over 100 tons of structural hollow sections to the Duodot project for steel frame warehouse building in southwestern Finland. Best-Hall built a logistic warehouse building for its customer for storing tires. The building is a combination of two halls, one part is 87 meters long, 44 meters wide, and the height is 9 meters from the lowest point. The other part is 132 meters long, 33 meters wide and 9 meters high.

Active collaboration to serve end customers - High quality tubes speed up the production
SSAB has been collaborating with Ateno for Tubular products since 2014. Over the years, delivery volumes have grown significantly and collaboration has deepened. SSAB currently supplies both hollow sections and precision tubes from tube mills. Products from precision tubes are further processed for use in, for example, mechanical engineering and the furniture industry. Parts of hollow sections are processed into parts of transport and steel construction. Ateno also makes forest machine parts from high-strength steels. In addition to tubular products, SSAB also supplies significant quantities of sheet and profile products to Ateno.
