Composite profiles



“Composite profiles” are obtained through the combination of two different processes:  Hot Extrusion  and  Laser Welding.

Siderval, thanks to an efficient combination of “Extrusion” and “Laser Welding”, succeed in the new project of producing profiles with bigger dimensions, more complex from a geometric point of view, with different shapes and different steel qualities.

By combining materials with different physical and chemical characteristics, a single- solid- continuous piece is produced capable of responding adequately to the strain generated by external stresses, redistributing it optimally.

“Composite profiles” are increasingly popular solutions in the architectural and engineering sectors because, thanks to their unique characteristics, they ensure high-level performance and undeniable benefits from various points of view.

“Composite profiles” are resistant and characterized by high durability, but they are also extremely versatile in terms of applications: they can in fact be used for constructions and infrastructures of various types.

These “special profiles” offer a transversal applicability that makes them the best solution from an economic and structural point of view.

For this reason, composite profiles are particularly used for the construction of structural elements.


By efficiently combining two different production processes, hot extrusion and welding, Siderval has succeeded in:

  • produce larger profiles
  • produce more geometrically complex shapes
  • produce a profile made up of different shapes and a combination of different steel grades.

Siderval is therefore able to offer “tailor-made solutions” by combining the hot extrusion process with welding, thus opening up new and cost-efficient perspectives. The advantages of “composite profiles” obtained by combining hot extrusion and welding are:

  • Possibility of having larger profiles and more complex geometries than extruded ones
  • High design flexibility
  • Combinations of profiles with solid and hollow sections can be produced simultaneously
  • Possibility of producing profiles made of different steel grades and shapes
