The image shows an automated bending line with CNC technology, where steel tubes are precisely shaped without altering their mechanical properties. This process reflects the company's commitment to CORVATS ESPECIALS SL (COES) with excellence in the cold tube bending, a key technique in the modern metallurgical industry.
What is cold tube bending?
The cold tube bending is a mechanical process by which metal tubes are shaped without the application of heat. Unlike hot bending, this method maintains the properties of the material intact, achieving results of high dimensional accuracy and high quality finishes. At COES, This process is applied to a wide variety of materials and diameters, ensuring tight tolerances and uniform radii.
Advanced technology for flawless results
The combination of state-of-the-art machinery and numerical control software (CNC) allows COES to offer perfect, repeatable bends adapted to the requirements of each customer. The equipment used allows us to work with carbon steel, stainless steel, copper, aluminum and special alloys.
High precision CNC bending
The CNC system ensures total repeatability in series production, minimizing errors and optimizing times. In addition, it enables 3D pre-design, which reduces prototyping costs and improves overall efficiency.
Advantages of cold bending over other methods
- Maintains the structural strength of the tube.
- It does not generate oxidation or thermal deformation.
- Allows precise and constant bending radii.
- Reduces energy consumption by not requiring heating.

Frequently asked questions about cold tube bending
What is the difference between cold bending and hot bending?
Cold bending is performed without applying heat, which maintains the strength and structure of the material. Hot bending, on the other hand, is used for large sections or materials that are difficult to deform, although it may alter the mechanical properties of the pipe.
What materials can be cold bent?
At COES we work with carbon steel, stainless steel, aluminum, copper and brass. The choice of material depends on the application and the technical requirements of the project.
What radii of curvature can be obtained?
Radii depend on tube diameter and material. Thanks to CNC machinery, we can achieve very tight radii without deforming the section or compromising structural strength.
Can I send my drawings to get a quote?
Yes, you can send us your drawings or 3D models and our technical department will evaluate the feasibility of the project, offering a customized proposal in reduced time frames.
Does COES also perform the subsequent assembly or welding?
Yes, we offer complementary services of tube welding and assembly of structures, which facilitates the integration of bent parts into complete systems.
