A special jury prize was presented at the Équerre d'argent 2019 awards in Paris on 25 November. The prize was awarded for the Simonne-Mathieu tennis court designed by architect Marc Mimram in the Roland Garros Stadium in Paris. Gearing up for the 2020 French Open, works are being carried out at the Roland Garros Stadium, including a retractable roof built with ArcelorMittal crane rails.

The competition

It was a jury chaired by the architect Paul Chemetov and composed of previous winners of the awards that the nominees of the Équerre d'argent 2019 had to convince. Twenty achievements were in contention, and the selection was made by the editors of Moniteur and AMC from some 220 applications divided into four categories: Structures; Culture, Youth & Sport; Activities; and Habitat.

Winners

The Julia-Bartet Residence, a training centre for apprentices and the distribution centre for the ‘Restos du coeur’ in Paris, designed by the architect Charles-Henri Tachon, won the Équerre d'Argent 2019 prize. Four other projects have been awarded respectively in the categories mentioned above. The prize for the Première Œuvre (First work) 2019 was awarded to a glassware workshop in Brioude (Haute-Loire), designed by Antoine Dufour Architects.

In May 2020, all eyes will be on the French Open / Roland-Garros tournament. While encouraging Novak, Serena, Rafael, or Roger, we invite you to admire the new retractable roof of the central court! Thanks to ArcelorMittal Rodange rails, your favourite players will be protected from the rain.

Premium rails provided in record time for the French sports monument

The Rodange site produced the 44 crane rails used for the construction of the retractable roof of the court. The A150 rails are the largest in our DIN range and were produced in 110CrV of superior quality. This shade has long been exclusively developed by ArcelorMittal with special straightening to ensure perfect track alignment.

The rails were mainly produced for the Philippe Chatrier central court roof. Once the rails were manufactured, the finishing operations were managed and organised in Yutz, France for:

• Cutting: The rails were cut to length according to customer specifications, including 45° corner cuts while respecting the required lengths with a tolerance of +/- 1mm.
• Hardness: The A150 are the highest quality in the range.
• Handling: Made with textile straps only, without magnets or chains, despite the size of the rails (the A150 are the largest rails in the range of crane rails produced in Rodange).
• Fast delivery

In total, it took only two months between ordering and shipments to provide the end customer with completely finished rails - from production to delivery. Thanks to good internal cooperation, we were able to provide the customer with a complete solution.

The revival of an iconic tennis court

Built in 1928, the Philippe Chatrier central court has undergone a complete renovation to modernise the stands and build a retractable roof.

This roof will not only allow the organisation of night games, but will also protect players from the rain in case of bad weather. It is composed of 11 panels of 100 metres and 350 tonnes each which slide on our rails. Thanks to our high quality products, this 3850-tonne roof will open and close in 12 minutes.

Looking for technical details for structural steel grades? Constructalia has got you covered. Check out our new steel grade pages that include mechanical, technical, and coating property details.

Magnelis® structural steel grades

Magnelis® structural steel grades include: S350GD, S390GD, S420GD-HyPer®, S450GD-HyPer®, and S550GD-HyPer®.

These metallic coated structural steels are mainly used in construction, road and railway infrastructure, agriculture and farming, solar energy generation, and tubular applications.

Magnelis® is a flat carbon steel product coated on both sides with a zinc-aluminium-magnesium alloy. This alloy, composed of 93.5% zinc, 3.5% aluminium, and 3% magnesium, is applied by means of a continuous hot dip galvanising process. This optimum chemical composition has been selected to provide the best results in terms of corrosion resistance.

Indaten® structural weathering steel grades

Indaten® S355W structural weathering steel grades are fine grain, high strength structural steels offering high yield strength and improved corrosion resistance in specific aggressive environments. These grades have excellent weldability with all the usual welding processes because of their low carbon content and fine grained structure.

When used uncoated and exposed to bad weather, an oxide layer develops on the steel surface, forming a purplish-brown, finely grained patina that bonds very strongly to the steel and protects it. With their characteristic colour, steels with improved atmospheric corrosion resistance are used in architectural projects like bridges either to harmonise with the environment or to optimise maintenance costs all along the construction life cycle.

The Research Institute of Sweden has renewed its certification of Magnelis® ZM 310 and its use as corrosion protection for steel sheets for indoor and outdoor applications. Its use is suitable for corrosivity class C5 according to the SS-EN ISO 12944-2 described class based on a deemed expected lifetime of 15 years.

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.
