Tube machining

Tube bending, pipe bending, section bending

With over 30 years’ experience in bending tubes, pipes, sections and tubulars in stainless steel, aluminum and iron, we are one of the few companies in Europe capable of bending cross sections with external diameter of the tube up to 219 mm.

Types of tubes and relative cross sections

We bend rectangular, round and square tubes, and section bars of various kinds.

Round tubes

Square tubular elements

Rectangular tubular elements

Section bars

Metal alloys

We process metal tubes, tubular elements and section bars in our innovative bending department in all the following alloys:


The bent tube in steel is definitely the most widely used because of the suitability for cold bending of this alloy.

Since it is the product most often requested, Tecnocurve disposes of a wide range of equipment for bending square and rectangular tubular elements, round tubes and section bars

Stainless steel

Bending stainless steel tubes is simpler than bending tubes of carbon steel.

The bent stainless steel tube is chosen, however, for its resistance to corrosion or because in certain sectors the esthetic appearance of the tube is more important.


The technical characteristics of aluminum, particularly its reduced elongation percentage, make it the most difficult to bend. Bending tubes in aluminum requires selection of the most suitable metal alloy, and requires extensive experience in processes of bending tubes and section bars in aluminum.

For best results it is essential to use CNC tube bending machines of the latest generation, operated by expert professionals.


The quality of the workmanship achieved with our FULL ELECTRIC CNC machinery ensures great accuracy and repeatability in medium and large production runs.

Tube bending methods in combination with other processes

Tube bending is often done in combination with other processes. By combining several activities, we are able to speed the production process as a whole, without ever sacrificing quality and precision.

Tube bending and roll bending

Combining tube bending and roll bending these two processes enables us to create unique geometrical shapes.

Roll bending and laser cutting

With laser cutting done immediately prior to bending, which is the cold deformation process as such, we are able to produce holes, slots, mitre cuts and many other processes, speeding the production process in its entirety.


Without laser cutting combined with bending, the time and costs would increase because the other operations would have to be done after bending, which would involve tooling more machines, which would require additional steps.

Tube bending and milling

The bent tubes are taken up again with accessory processes capable of increasing the accuracy of the result.
Going into detail, bending is a process of cold deformation which gives the tube a rather narrow fixed average bend radius. It is achieved using CNC machinery that, thanks to the computerized control, can ensure processes with a high degree of precision and repeatability.
At Tecnocurve, we guarantee high quality workmanship, supported by thorough analytical feasibility studies right from the first stages of design of the tube or section bar to be bent.
We rely on professional collaboration because our machines must always be operated by experienced personnel, so that we can guarantee a product of excellence and establish a lasting, valuable relationship with the client, based on trust.
