Tube Bending and Curving in Stainless Steel and Other Metals

Tube bending is one of the most requested metalworking processes across numerous industrial sectors, especially when resistant, precise and custom-made components are necessary. Siera, headquartered in Conegliano (Treviso), specialises in stainless steel tube bending and the curving of other metals, offering customised solutions that meet high standards of quality, safety and performance.

Thanks to advanced technologies, the expertise of its technical team and constant quality control, Siera realizes custom tube bending even on complex tubing, including high-resistance materials or small-diameter tubes such as stainless-steel microtubes, drawn microtubes and capillary tubes. Its extensive know-how allows the company to support clients in professional catering, furniture production, the medical sector, automation and many other industries that require high precision.

REQUEST INFORMATION

Tube Bending: Curving Stainless Steel and Other Metal Tubes

The stainless-steel tube bending service offered by Siera makes it possible to shape tubes of different sizes and thicknesses, ensuring uniform curves without flattening. This is achieved through the use of advanced CNC machinery that guarantees repeatability, tenth-of-a-millimetre accuracy and optimised management of both small and medium-large production batches.

Materials processed include:

  • AISI 304 and 316 stainless steel, ideal for furniture, food industry, HO.RE.CA., medical equipment and environments subject to wear or chemical aggression.
  • Aluminium, lightweight and suitable for design structures, automation systems and mechanical components.
  • Other metals on request, with each project assessed according to its intended final use.

Siera’s techniques allow stainless-steel tubes to be bent while maintaining the material’s properties. Combined processes such as cutting, drilling, roll bending and welding can also be carried out, enabling the delivery of components ready for assembly.

Tube bending is available even for reduced diameters, such as stainless-steel microtubes widely used in technical instruments and the medical sector. Each process is designed according to the customer’s specifications in order to achieve a tailor-made, functional and high-quality result.

Examples of Our High-Precision Tube Bending Service

Siera’s tube curving department can manage projects with different range of complexity, geometry and intended use. Some representative examples of our work:

Elements for Furniture and Design
