Dextra Partners with NCS Steel, Offering Rolltec Couplers in Europe

Posted on by Kansuda Visesthanakorn

 

Dextra is proud to announce its newest partnership with NCS Steel, a dynamic new player in the Portuguese construction industry. As the latest addition to Dextra’s growing network of cut & bend fabricators in Europe, this collaboration reinforces our commitment to delivering high-quality reinforcement solutions for major infrastructure projects across the continent.

A Powerhouse Backed by Industry Leaders

Though newly established, NCS Steel brings a wealth of expertise to the market. It is a joint venture between three of Portugal’s most prominent steel suppliers:

  • Nordesfer – Armazéns de Ferro S.A.
  • J. Justino das Neves S. A.
  • Metalofarense

By combining their extensive industry experience and resources, NCS Steel is poised to elevate reinforcement solutions in Portugal’s growing construction sector.

State-of-the-Art Facility in São Lourenço

Strategically located in São Lourenço, near Lisbon, NCS Steel’s brand-new facility is designed to set new benchmarks in precision, efficiency, and product quality. The plant is equipped with advanced machinery and cutting-edge technology to meet the rising demand for reinforcement-related products and services.

Expanding Access to Dextra’s Rolltec Coupler System

A key aspect of this partnership is the integration of Dextra’s Rolltec coupler system into NCS Steel’s portfolio. Rolltec, known for its superior strength, reliability, and ease of installation, has been a preferred reinforcement solution in major European projects, including:

  • Storstrøm Bridge (Denmark): A critical infrastructure project enhancing connectivity between Zealand and Falster.
  • Oosterweel Ring Road (Antwerp, Belgium): One of Europe’s largest urban mobility projects aimed at transforming the city’s transport network.

By bringing Rolltec to the Portuguese market, NCS Steel will enable local contractors and engineers to benefit from high-performance reinforcement technology, ensuring faster, safer, and more efficient construction.

A Shared Vision for the Future

This partnership represents more than just a business collaboration, it is a shared commitment to innovation,

Industrial Bridge, Chile

 

Dextra’s engineering expertise and innovative products played a pivotal role in the construction of the Industrial Bridge in Chile. As part of the project, Dextra supplied its Rolltec mechanical splice system, ensuring robust and reliable rebar connections. Additionally, Headed bars were provided to enhance anchorage performance, a critical requirement for the bridge’s structural integrity.

The project also utilized Sonitec crosshole sonic logging (CSL) testing tubes, facilitating thorough integrity testing of concrete piles, ensuring long-term safety and performance. These advanced solutions reflect Dextra’s commitment to supporting complex infrastructure projects with high-quality, tailored products.

The Industrial Bridge stands as a testament to modern engineering and showcases the critical role Dextra’s solutions play in shaping resilient and efficient infrastructure worldwide.

Tanger Med 2 Port

Tanger Med 2 Port

Tanger Med 2 is the expansion of Tanger Med, a multipurpose deep-water seaport located a few kilometers east of Tangier, Morocco, facing Gibraltar.

The port expansion aims to increase the yearly capacity of the largest port in Africa by 5.2 million containers.

For this large infrastructure project, Dextra supported contractor Bouygues with a rebar splicing solution for the reinforcement of the caissons.

Dextra supplied its Rolltec solution, which is AFCAB-certified, a requirement for this project. Two Rolltec machines were installed to support the threading activities, completing 360,000 threads in total (180,000 Rolltec couplers).

The couplers were used in the reinforcement of the caissons, which were as tall as 20 to 24 meters. The couplers provided:

  • Temporary openings to solve congestion issues in the reinforcement within the caisson, creating safe passages for men and equipment during the installation phase.
  • Horizontal wall-to-slab connections (from the inside of the caisson perimeter to the slab). For this application, couplers were left pending, allowing the slip form to go up.

Belo Monte Dam

The Belo Monte Dam is a hydroelectric dam built on the Xingu River in the state of Pará, northern Brazil. Upon its inauguration, it will become the second-largest dam in Brazil and the fourth-largest in the world, with a total maximum capacity of 11,233 MW.

For this major dam project, Dextra Do Brasil continuously delivered to contractors its Rolltec mechanical rebar splicing solution between 2011 and 2016.

Rolltec is the most popular rebar splicing solution in Brazil, offering a competitive alternative to lap splices.

A total of 250,000 couplers have been used in the Belo Monte Dam, incorporated across all parts of the structure.

Rebar preparation is supported by a unique lightweight machine, which can be operated by a single person.

The Rolltec machine is relatively easy to transport and convenient to install, even in remote locations such as dam construction sites.

Causeway across Kuwait Bay

Causeway across Kuwait Bay (Jaber Causeway)

 

The Main Causeway across the Kuwait Bay is a 36-km-long project currently being built north of Kuwait City. It will ultimately be connected to Doha Link, another sea link project west of Kuwait City, which will connect the Jaber Causeway sea link, one of the largest civil engineering projects ever built in the Middle East.

The main causeway across Kuwait Bay stretches north of Kuwait City. It is expected that the link will greatly contribute to the development of the northern part of Kuwait. To achieve that, the Causeway will literally cut across Kuwait Bay with a 27-km sea link.

Bridge pylons and girders

For the visible part of the sea link, Dextra worked with contractor Hyundai to offer high-tensile post-tensioning bar solutions.

Dextra Smooth PT Bar Grade 835/1050s were used all along the sea link for the connection of the precast girders together.

For part of the sea link, which is topped by a metallic cable-stayed structure. Higher performance bars in Grade 1050/1200 were used to offer a vertical anchoring point between the pylon and the reinforcement of the pile. PT Bars were delivered with a full corrosion protection accessory set by Dextra so that the bars will resist the marine conditions.

Crosshole Sonic Logging tubes

For the concrete integrity testing of the onshore and offshore foundation piles, Dextra supplied around 400,000 linear meters of Sonitec tubes, which are easy to set up and reconnect without the need for welding, which significantly increases the productivity of the pile assemblies.

Once installed, the tubes are firmly in place, supporting without issue the cage lifting and handling.
