The last of the 2,744 segments for the Delta Junction viaducts has just been assembled by our teams at the Kingsbury prefabrication yard.
In total, nearly 17,000 tonnes of reinforcement steel have been assembled by our teams for this major HS2 infrastructure project, with up to 70 people mobilized at peak activity.
This milestone marks the successful completion of months of precision work, coordination, and commitment.

A major railway maintenance hub is taking shape in Marcheprime to support the high-speed trains operating on the South Europe Atlantic line.
Our SAMT team is contributing to the construction of a massive raft foundation: 220 meters long and 60 meters wide, totaling 13,200 m² of rebar to install. That’s a lot of rebar to place!

“Hands, those magicians of the real.” Christian Bobin

In 2026, more than ever, let’s trust the knowing hand. The one that shapes, invents, and assembles. The one that builds the invisible and makes the impossible real. Happy New Year to all those who work with their hands — and to those who know how to truly value them.

PS: To our safety champions, don’t worry. Our team wears gloves on site. We just took them off for 12 seconds… for the sake of art. Yes, we timed it.

After several months of slowdown due to technical issues, pile workshops are gradually resuming and work on the supports is progressing rapidly. The manufacture of voussoirs has reached cruising speed: two concrete elements are produced every day.

Big shoutout to our team of 20 reinforcement specialists, who came from mainland france, french guiana, reunion and guadeloupe to assemble the steel structures of this major bridge.

Building on its expertise in reinforcement, SAMT is expanding its know-how with a new offering: the manufacture of stainless steel reinforcement bars.

A dedicated production hall in Salon-de-Provence now houses a machine specifically designed to work with stainless steel in a contamination-free environment (zero dust or carbon steel chips). The result: impeccable quality and performance suited to the most demanding projects.

Why stainless steel?
• Exceptional corrosion resistance
• Superior durability and low maintenance
• Better fire resistance and performance in seismic zones
• Architectural freedom and concrete optimisation
• A sustainable and responsible solution

A concrete example: the voussoirs of the new Larivot bridge in Cayenne (French Guiana) were entirely reinforced with 1.4462 stainless steel, guaranteeing unprecedented longevity in a particularly aggressive environment.

For years, SAMT Ingénierie has been supporting clients worldwide with the design, prefabrication, and handling of XXL reinforcement structures.

Our expertise includes:
• Adapting or designing optimized rebar plans for prefabrication,
• 3D modeling to validate each step with engineers, clients, and project managers,
• Designing custom jigs, lifting beams and special tools,
• Drafting detailed lifting procedures for maximum safety,
• Deploying skilled installation teams across France and internationally.

From ITER’s Tokamak to British railway bridges, London tunnels, and French nuclear plants — our tailor-made solutions enhance performance, safety, and quality.

Got a challenging project? Let’s talk.

Last Thursday, we had the honor of taking part in the ITER Safety Day in Cadarache. A day full of exchanges on a key issue: safety on site. Some highlights of the day: assembly and opening of our stand, Round table with Frédéric Thirion, signing of SAMT’s commitment to safety at ITER, interview with Hamissi Rabah on safety best practices, handover of the Rule #5 – Lifting panel to ITER’s safety team…
Quelques temps forts de la journée : montage et ouverture de notre stand, Table ronde avec Frédéric Thirion, signature de l’engagement de SAMT pour la sécurité à ITER, interview de Rabah Hamissi sur les bonnes pratiques de sécurité, remise du panneau Rule #5 – Lifting à l’équipe sécurité d’ITER…

A big thank you to ITER for this inspiring initiative, and congratulations to all the teams committed to making safety a shared culture.

Today, we are on the ITER site in Cadarache, together with 11 other companies, for a day dedicated to a key issue: safety.

At SAMT, we are showcasing our expertise in lifting operations, precision, and performance in the field of reinforcement for reinforced concrete.

It is an honor to have been working with ITER for many years, growing together, and sharing this moment with inspiring and committed companies.

How do you install 38 tons of reinforcement for a 26-meter pile cap in just 2 days?

Here’s SAMT’s step-by-step recipe for success:
• Adapt the initial reinforcement plans to allow for prefabrication
• Model all changes in 3D for validation by the client, engineering office, and project manager.
• Cut and shape the rebar in our St Chamas (South of France) facility.
• Accurately survey pile locations and starter bars on site.
• Prefabricate two cages (2.30 x 2.30 x 13 m), each weighing 19 tons.
• Load both cages onto semi-trailers using a 100-ton mobile crane.
• Cross France to arrive on D-Day in Nantes.
• Install both cages through four large-diameter piles in half a day.
• Connect the cages the next day.
• Ready for formwork and concrete!

A great example of coordination between design, workshop, logistics, and field operations. We’ll do it all again in late August for the second pile cap. Hats off to all our teams for this seamless execution.

High-quality steel columns with base plates and integrated inserts, prefabricated by our SAMT Indian Ocean teams, are now heading to the Albioma site at Bois Rouge. These structures will be part of the new waste-to-energy (WtE) unit, which will convert 70,000 tons of waste into electricity using refuse-derived fuel (RDF) — a major step forward for the island's energy transition.
