Structural hollow sections

Hollow structural sections supplied from Stena Stål’s Swedish facilities. The shaping operation of hollow structural section can be performed either
cold or hot. Hot-formed profiles have lower internal stresses than cold-formed
which means that there is less risk for shape changes if they are cut, welded,
and machined. The principal advantages of cold-formed profiles are better
dimensional tolerances and surface finish. Hollow profiles are used as a
complement to beam profiles in building construction and civil engineering.
