Variable radius tube bending

We perform variable radius bends on metal tubes and profiles in stainless steel, iron, aluminum, zinc, and other alloys, ensuring precision, continuity, and customized processing for every need.

Precise machining on metal profiles

Variable radius bending is an advanced process that allows for multiple bending radii within the same metal tube or profile. This technique allows for progressive curvatures, even of different sizes, on round, square, and rectangular profiles.

At Metal.Car., in Turin, we use professional tube benders that allow us to perform controlled cold deformation, ensuring profile continuity, stability, and consistent quality for both individual handcrafted pieces and serial production.

Absolute precision

Variable radii obtained with continuity and control along the entire length of the tube.

Integrity of the material

How variable radius pipe bending works

Variable radius refers to the ability to perform multiple bends with different radii within the same piece. This process is performed using tube benders equipped with dedicated components (die, clamp, mandrel, and slide) that allow for control of the profile deformation during each bending phase.

The most delicate aspect concerns the intrados of the tube, the internal area of the bend subject to the greatest mechanical stress. Correct parameter settings and the operator's experience help limit irregularities, unwanted bends, or crushing, achieving a uniform and stable bend.

Metal.Car. uses bending machinery daily for serial production and high-precision craftsmanship, guaranteeing a final result that meets the customer's technical specifications.

Advantages of pipe bending

High precision: multiple controlled radii along the entire profile.
Material integrity: reduction of irregularities on the intrados.
Flexibility: possibility of complex and progressive curves.
Reliability: constant process control even on serial productions.

Variable radius pipe bending in metal carpentry

Variable radius bending is one of the most versatile and sought-after processes in the metalworking industry. Thanks to the ability to achieve progressive curves and different radius combinations, it is ideal for functional, aesthetic, or structural applications.

Metal.Car. specializes in the cold forming of metal profiles, ensuring consistent quality for both artisanal and mass-produced projects. Our experience allows us to manage the typical critical issues of this process, such as internal stresses and potential irregularities on the underside, ensuring a clean result that meets the required specifications.
