Custom Profile in steel - Uniqua Tower | Special Hot Extruded Steel and Stainless steel Profile for curtain wall and façade is a custom-made steel mullion for curtain wall produced by hot extrusion.

Free forms and special profiles are innovative solutions for sophisticated steel structures designed by ambitious designers. If your project requires a unique design, custom-made hot extruded steel and stainless steel profiles are your answer.

The hot extrusion process produces special steel shapes according to the customer drawings. We can create custom-made profiles in a wide range of dimensions and qualities: stainless steels, carbon steels, superalloys and titanium grades.

This specific section was used for project Uniqua Tower in Vienna as a steel façade mullion.

It is a hollow T shape in carbon steel. The dimensions refer to a specific project.

The profiles can be used for curtain walls as uprights and other structural and mechanical applications, especially when high mechanical characteristics are needed.

The dimensions of this product refer to a specific project.

Different sections and sizes on request. We create your unique profile.


Tailor-made profiles / Seamless and complex shapes / Solid and hollow sections / Very high design flexibility / Small volume production / Midsize to large profiles / Low tooling cost / Prototyping possible

Possible results

Different thickness within the same section / Integration of grooves / Hollow profiles for lighter structures / Hollow profiles for water heated curtain walls
