Matière uses high strength ArcelorMittal steels to provide vital bridges in remote areas

The French company Matière first introduced its Unibridge® concept in 2004. Today these patented structures are shipped around the world where they are used as permanent or temporary crossings for vehicles and pedestrians. Thanks to their modular nature and ease of construction, the Unibridge® is particularly popular in remote regions where materials and skilled workers are hard to find. The solution uses ArcelorMittal’s S355K2+N and S460M high strength steel plates which are known for their durability, giving the Unibridge® a 100-year design life.
Close cooperation with ArcelorMittal
“The close cooperation between ArcelorMittal Europe – Flat Products and ArcelorMittal Projects, together with the quality of the plates produced in ArcelorMittal’s mill in Gijón, Spain guarantees the best level of service for Matière,” says Michaël Regal, Account Manager for Matière at ArcelorMittal Projects.
Since 2018, heavy plates from our Gijón mill have been successfully delivered to Matière and its subcontractors in France, Belgium, and Portugal. “When a very short lead time is required, we are in the position to offer a delivery in less than a week at any Matière yard thanks to our own stock of plates, beams, and tubes,” says Michaël Regal.
Designed for remote and developing regions
The Unibridge® was initially developed as a solution for the military but was never adopted. Matière immediately saw the potential of the solution in developing countries and remote locations as Hervé Blanc, Deputy General Manager of Matière, explains: “These areas typically require many bridges, but there is a lack of resources and skills to produce them.”
Ease of transport and construction in remote areas was a key consideration in the early design phase notes Hervé Blanc: “We developed a structure that does not require welding on site, and which can be assembled without heavy lifting devices. In some cases, the girders can be offloaded and pushed into place with an excavator, or sometimes by the truck that delivered them. It takes around five days to install a typical two-lane (nine-metre wide) bridge that is 40 metres in length.”
The only preparatory work that needs to be done is preparing the bridge’s abutments. That can be done by an onsite partner who can complete the work while the bridge is being manufactured and shipped.
Simple design makes transport simple and efficient
Matière adapted the design to ensure two of the box girders which form the basis of the Unibridge® could fit into a standard shipping container. “Our box girders are 11.4 metres in length, ensuring two can fit into each container,” says Hervé Blanc. “The girders can be pinned on site to create a maximum length of 60 metres. But if you include piles, you can extend the length of the bridge significantly. We’re currently constructing a Unibridge® in the Philippines which will be four kilometres long. There is no limit on the width of the Unibridge® as the box girders can be simply linked with spacers.”
Weight saving with S460M
Another consideration was keeping the weight of the container below 25 tonnes. “Thanks to the use of ArcelorMittal grades such as S460M, weight is not an issue,” says Hervé Blanc. “In the beginning we constructed the entire bridge from S355, and a typical box girder weighed 12 tonnes. Today we are using more S460M, and the average weight is 10 tonnes, a saving of almost 20 percent. Now we are looking at replacing the S355 with S460M from ArcelorMittal to achieve even greater weight savings. That will reduce the cost of transporting and installing the bridges.”
Low maintenance steels extend bridge life
One of the key advantages of ArcelorMittal’s steels is that they don’t need a lot of maintenance as Hervé Blanc explains: “ArcelorMittal’s steels are very tough! The bridge simply needs a fresh coat of paint every 15 to 20 years to protect it. In some areas we recommend a C5 paint system due to the marine environment.”
A sustainable solution thanks to steel
As the Unibridge® is prefabricated, there is no waste produced on site. All scrap steel produced in Matière’s factories is recycled or reused. The sustainability of the solution is further enhanced as it can be transported by ship from Matière’s plants in Europe.
The bridges themselves can be fully recycled at the end of their life or disassembled and reconstructed in another location. “The company which is building a traffic deviation around Strasbourg, France is renting two of our Unibridge® solutions to divert traffic around the roadworks,” says Hervé Blanc. “They will be in place for two years before they are dismantled and reassembled in another location.”
To date, Matière has installed over a thousand Unibridge® solutions in more than 35 countries around the world. “The introduction of the Unibridge® in 2004 was the beginning of Matière’s success story,” says Hervé Blanc. “But every Unibridge® is also a human success story. They can cut a journey that normally takes a day, to just an hour. This dramatically changes the way people in remote areas live and interact.”
About Matière
Matière was founded in 1932 and is still a family-run company. The business operates three plants in France and one in Belgium. All the plants produce components for Matière’s bridge business. In addition to the Unibridge®, Matière produce reinforced and prestressed concrete bridges, metal bridges, and composite structures which use both metal and concrete. The company is also involved in the repair of concrete and metallic bridges. Around 65 percent of its bridges are exported outside Europe.

Award-winning InQuik system uses Magnelis® to install innovative bridges quickly

Australian company InQuik has developed a unique method of building bridges which can be implemented quickly using only low-skilled labour. The globally patented technology utilises Magnelis® from ArcelorMittal Europe – Flat Products to create the formwork of a bridge, which is then filled with concrete to create the bridge deck. Although the bridges are designed for a service life of 100 years, experts believe that the use of Magnelis® could double that without the need for significant maintenance. With hundreds of thousands of bridges needing replacement around the world, the potential for the InQuik system is enormous. The innovative design of the InQuik system was recognised when it won the 2019 T.C. Graham Prize from the Association for Iron & Steel Technology (AIST).
The InQuik system
The InQuik system was developed by a family team including father and son Bruce and Logan Mullaney and Bruce’s brother-in-law, Jim Howell. Their original goal was to improve the systems used to transport modular housing with a collapsed container system. “When we went to register our idea of a reinforcement to hold the deadweight of concrete, the patent office told us this was completely new,” explains Logan Mullaney, now managing director of InQuik Bridging Systems. “We immediately started to think of other ways we could utilise this technology.”
With demand for bridges soaring globally, they seemed to be an ideal application notes Logan Mullaney: “We realised that by putting a truss in a reinforced steel shell we could hold the temporary load of the cement until it cured. Our first trial bridge was constructed on our own property in Australia. We built three in the first year and eight in the second year. This year, our third, we will install around 40 InQuik bridges.”
Magnelis® provides long-term strength
A key challenge was to identify a good material for the formwork which holds the concrete until it dries completely. “At first we thought about using galvanised steel, but over time this will rust and fall away,” says Logan Mullaney. “While the formwork is sacrificial, we realised that the sight of corroding metal would reduce user confidence in the bridge and increase the amount of maintenance required. We needed a more durable solution.”
InQuik was introduced to Magnelis® through a contact in Australia. “Magnelis® allows us to leave the formwork of the bridge in place as it has an aesthetically pleasing finish – and it is durable,” says Logan Mullaney.
Another key advantage of Magnelis® is the protection it offers to the concrete deck. “Because the formwork remains, the concrete and internal reinforcing steel are protected from corrosion,” explains Logan Mullaney. “That means the bridge will last longer. Engineers have estimated the useful life of an InQuik bridge could be well in excess of its 100-year design life, potentially up to 200 years.”
Confidence in quality
The Magnelis® formwork helps to contain plasticisers and water-soluble chemicals which occur in the concrete. Magnelis® ensures the preservation of natural resources as it uses significantly less zinc than pure zinc coatings. Zinc runoff is also reduced dramatically compared to galvanised steels.
“Magnelis® is not well known in Australia and we are one of the only companies utilising it,” notes Logan Mullaney. “But ‘Made in Europe’ is a quality label for Australian companies. Together with the fact that ArcelorMittal is the largest steelmaker in the world, this gives our customers – and bridge users – confidence in the system.”
Portable technology can be deployed globally
Magnelis® is imported into Australia from ArcelorMittal Bremen where it is produced. InQuik maintains a healthy stock in Australia as there is currently a four-month lead time on orders. “We’re looking how that lead time can be reduced so InQuik doesn’t have to maintain such a large stock of material,” notes John Robbins, export manager for ArcelorMittal Europe – Flat Products.
Compared to a conventional reinforced concrete bridge, the InQuik system is up to 90 percent more steel-intensive. However, the bridges are more cost-effective as they can be prefabricated and installation time is significantly lower explains Logan Mullaney: “InQuik bridges are standardised, pre-certified, and can be mass-produced. And it is possible to transport an entire bridge on one semi-trailer. You just back the truck up to the site, install the components, and then fill them with concrete. It only takes a small crane and a few days to build the bridge. Customers typically save between 20 and 50 percent compared to a conventional bridge due to the lower installation time and work, low risk, and less cranage.”
About InQuik Bridging Systems
InQuik manufactures standardised, pre-certified, mass-produced bridges which can be easily transported anywhere in the world. The solution makes building a bridge quick, simple, low-risk, and cost-effective. InQuik employs 15 people in its sales and delivery team and produces systems at three factories in Australia. InQuik is currently preparing for expansion into the USA, Asia, and other regions around the globe.

Footbridges are a symbol of soft transportation mode development in urban areas.
Like any other bridge, footbridges must be long enough to cross the obstacle below and high enough not to interfere with whatever passes beneath the bridge.
However, it is an increasingly common requirement for footbridges to be ‘landmark structures’. Therefore, the appearance of the structure is met with more attention than usual.
In most footbridge cases, a fairly light structure is required as the loads they carry are quite modest. This may result in some very innovative and unique forms of construction.
