SSAB’s cold-formed steel sections are suitable for practically any kind of steel structure, whether for commercial or residential buildings, machines or appliances.

    The accuracy of the cross-sectional form and good formability for high-strength material makes it possible to create long-lasting and light structures.

    The steel in SSAB Domex Section meets or exceeds the requirements of EN 10149-2, EN 10025-2 or EN 10346 depending on selected product. SSAB Domex Sections' tolerances meet or exceed, when applicable, the requirements of EN 10162.

    SSAB Domex Sections are available in various shapes and thicknesses. The maximum length of the sections is 21 meters, cut-to-length sections are available upon request.

    EN 10162

    When you choose cold-formed steel sections from SSAB, you’re investing in materials that meet all the requirements of European standard EN 10162. Our cold-rolled structural steels meet all the technical delivery conditions under this standard, ensuring that you only get the highest quality product.

    Introducing C section

    SSAB manufactures high-quality C section steel by cold roll forming the steel into a C shape.

    The C section consists of a wide web with two parallel flanges on the top and bottom of one side of the web and two lips.

    Uses for C section steel

    C channel steel often provides structural support in building construction that requires dimensional accuracy and high-quality steel. It is also used in automobiles, ships and other vehicles and to manufacture a variety of industrial, commercial and consumer products.

    • Window and door frames, gates, fences
    • Support for wooden beams
    • Roof rafters
    • Frames in cars, trucks and other vehicles
    • Girts, studs, braces, joists and other structural components
    • Conveyor rails
    • Bridges and truss structures
    • Power transmission towers, solar panel mounts
    • Home appliances, metal furniture

    C section sizes and grades

    We provide C section steel in the standard grade S235J2C+N in a range of sizes. You can request other steel grades, plus custom lengths, punching and more.

    Introducing U channel steel

    Cold-formed U channel steel is a highly accurate roll formed standard section

    SSAB’s cold-formed U channel steel sections are suitable for replacing hot-rolled beams in many applications.

    U channel steel sections include a very wide range of options for steel grades as well as steel dimensions. Dimensions exactly matching the application provide significant weight and cost savings. Each unit of weight saved by the U shaped steel channel will offer direct benefits in transportation and in the lighter weight of structures. Our cold-formed U channel steel sections are made according to EN 10162.

    Cold-formed U channel steel sections are manufactured by roll forming using SSAB’s high-quality steels. It is mainly used in the construction, transportation and manufacturing industries where dimensional accuracy and high-quality steels are required.

    SSAB’s cold-formed steel channels are suitable for replacing hot-rolled beams in many applications.

    Replacing hot-rolled UNP beams with cold-formed U channel sections

    Hot-rolled UNP beams can often be replaced with cold-formed U channel sections.

     The benefits of using cold-formed U channel steel sections include

    • The accuracy of the cross-sectional form and better straightness compared to the hot-rolled beam.
    • U channel steel dimensions for cold-formed sections are almost unlimited.
    • Cold-formed sections have a wide range of materials and the material can be selected depending on what is most appropriate to the application.
    • Steel U channel sizes can be adjusted to customer needs, thus reducing scrap and the need for further processing.

    This U-channel steel series has been developed with the same outside dimensions as hot-rolled UNP beams so that replacing hot-rolled beams is easier. The thickness is selected so that the cold-formed U-channel has the same bending strength, but it weighs less. Weight reduction has been achieved by using higher strength steel grade.
