Cold-formed 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. Standard steel grade is S235J2C+N, other steel grades upon request.

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.
