Specialized solutions for transportation

Vallourec offers solutions for all your automotive and transport tubular needs, from bearing tubes to axles to precision tubing and beyond. With our ranges of standard and premium steel grades, our products help optimize your designs while meeting or exceeding industry standards.

Our catalog of high performance grades combined with the advanced features of our seamless tubes enable to obtain the highest level of mechanical performance on the market, thus increasing the durability and mechanical loads without changing your design.
Load capacity can be optimized by using seamless tubular products instead of solid parts. Hot-formed seamless square and rectangular hollow sections provide superior static strength thanks to their tight corner radii. Excellent strength to weight ratio means lower weight for equal performance.
Thanks to their manufacturing process, seamless tubes provide homogeneous properties leaving no place for weak points, resulting in longer lifetime compared to other solutions.
Our Products

Rising to the challenge

Automotive and railway manufacturers, whether designing cars, trucks, wagons, locomotives or heavy-duty machinery, must balance competing demands. Regardless of the application, they need robust, light and durable components that meet strict safety standards and are cost-effective.
Our products are intended for:

  • Passenger cars
  • Commercial vehicles
  • Railway vehicles
  • Trailers
  • Two-wheeled vehicles

Precision tubing

Our full offer includes precision tubing for parts ranging from airbags to diesel injection pipes to transmission and suspension components and beyond. With a wide size range and tight tolerances, we can tailor-make a solution that meets your application needs..

Bearing tubes

Smartube, our simplified bearing tube solution, is a customer favorite. Produced by our subsidiary, Vallourec Bearing Tubes, Smartube is a customer award-winning solution for your bearing tube needs.


For both railway, commercial and heavy-duty vehicles, axle parts and housings must be ultra-resistant and extremely tough. Economic demands require material that offers easy, fast and precise machining combined with constant material properties. Our Structural Hollow Sections are ideal for friction- and resistance-welded axles, forged integral axles and axle units with machined axle hubs.

From a tube to an automotive component

With tools dedicated to the automotive industry, we also partner with our clients to supply pre-transformed tubes capable of meeting multiple component designs. We offer a range of services for these products, including heat treatments, surface preparation, measurements, cuts, marking, traceability, specific bundle preparation and just-in-time delivery.
