Steel Construction

Fulfilling onshore and offshore project specifications
With a wide range of tubular products, Vallourec remains a trusted partner for construction of onshore and offshore projects. Over the years, our solutions have been integrated into major projects around the world.
Onshore Projects
Onshore Projects

For many years, Vallourec has been producing quality steel frame structures, and more specifically hot-rolled circular, square and rectangular Structural Hollow Sections. Our solutions have been successfully integrated into some of the world’s most stunning architectural and structural projects. They have been used to construct iconic stadiums (Wembley Stadium in London, Stade de France in Paris, Allianz Arena in Munich), airports (New Bangkok International Airport, Hong Kong Airport), train stations (Berlin Central Station), and halls (Landesmess in Stuttgart, Hall 3 in Frankfurt). 

Also, in order to give buildings and structures a safe and solid foundation even on unstable ground, micropiles are used for stabilization. Vallourec’s Tecnipile® range of hot finished seamless tubes offers ideal solutions for all kinds of micropile applications, including building foundations of all kinds, mounting pads and stabilizers for landslide and flood areas.
Our products are also integrated into the construction of rollercoasters and other types of amusement rides. Steel girders made of our rectangular and square MSH sections are used in the design of rail systems. 

In addition, Vallourec developed PREON® box, a unique iterative planning software for column-free hall construction. This technology drastically simplifies the construction of wide-span steel structures and saves up to 30% in materials. Easy to use, it provides the planning data needed for processing a project at every phase, from foundation to detailed engineering. 

As your trusted partner, our teams work directly with architects and engineering consulting firms for all of our projects.

Offshore Projects
Offshore Projects

With products that resist harsh environmental conditions (including saltwater corrosion, fierce storms and very low temperatures), Vallourec provides solutions for the technological challenges inherent in offshore projects such as wind farms, subsea structures, platforms, jack-up rigs and installation vessels.

With the standard range of Structural Hollow Sections as well as a series of special grades, our solutions meet all specific requirements for offshore applications. Vallourec has additionally developed PREON® marine, an innovative system for offshore wind turbine foundations.  

Vallourec provides ideal construction elements for all needs in subsea applications. The mechanical, technological and geometric characteristics of our MSH sections meet and exceed defined standards in order to ensure cost-effective construction, durability and the safe operation of subsea systems. 

Today, designing modern jack-up rigs necessitates the optimization of construction, assembly, operation and maintenance processes. With mechanical properties exceeding all relevant standards, and excellent weldability—not to mention a wide range of outside diameters, wall thicknesses and special grades for offshore applications—Vallourec offers a comprehensive selection of tubes for the cost-effective construction of strong and durable rig modules. 

The need for increased drilling capabilities in midwater and deepwater exploration areas as well as the evolution of offshore wind farms has led in recent years to the design and construction of new floating equipment. Nowadays, drilling ships and special-purpose vessels feature highly efficient layouts with optimized dimensions and integrated application-specific units. Vallourec offers a comprehensive array of tubes for the cost-effective construction of the topside structures of special purpose vessels. 

Taking on your challenges: the Borssele Wind Farm Substation
In 2018, with RijnDijk, a Dutch steel construction specialist, Vallourec supplied 350 tons of Structural Hollow Sections as part of the construction of the Borssele Wind Farm substation. Located off of the coast of the Dutch province Zeeland, the substation needed to withstand strong winds, extreme humidity and high salinity. Our team’s contribution to the project was the provision of Structural Hollow Sections suitable for these complex conditions. 

For all your construction projects, Vallourec brings you with the solutions you need.

Customer Story
“Vallourec is an accredited supplier for Mack Rides, maker of amusement rides around the world. According to Mack Rides Marketing Manager Maximilian Roeser , "Our constructions have been precisely adapted to the specific material properties of Vallourec's Structural Hollow Sections, thus benefitting from features such as tight corner radii, straightness, excellent weldability and constant overall quality.”
“Installing the new narrow-gage railway bridge at Lanciau, Switzerland, required extremely fast production and installation. With only ten weeks to complete the job, we also had to ensure the new bridge would fit in with the natural surroundings. We worked hand-in-hand with the customer to ensure the success of this project.”
