Giving structure to Romanian stadiums
Sport has a very important place in Romania, especially football. ArcelorMittal Tubular Products Europe recently contributed to the construction of two stadiums in the country: the Craiova stadium, inaugurated in November 2017, and the Targu-Jiu stadium which will open this year. Steel produced in Romania was used for both projects with Hollow Structural Sections (HSS) produced in Iasi and made from coils produced by ArcelorMittal.
About the stadiums
Craiova stadium:
Architect: Dico and Tiganas architecture and engineering

100% Romanian steel from ArcelorMittal
Two football stadiums were recently built with ArcelorMittal steel, in Craiova and in Targu-Jiu. For both projects, ArcelorMittal Tubular Products Europe supplied HSS (in EN 10219 standard) to KonigFrankstahl, which were used to build the tribunes and the structure of each stadium.
The HSS were produced by ArcelorMittal Tubular Products Iasi, part of ArcelorMittal Tubular Products Europe. The sections were produced through the Electric Resistance Welding process, which consists of forming a tube with a steel strip by heating the edges and forming them together. The name of the process comes from the heat necessary for welding that is generated by electric currents passed through the steel strip prior to the weld being forged.
Quality, communication and just-in-time delivery
KonigFrankstahl is one of ArcelorMittal Tubular Products Europe’s most important distributors for the Romanian market. KonigFrankstahl has a long-term and strong partnership with one of Romania’s largest
construction companies CON-A (general contractor of these two projects) which demands punctual deliveries to be able to meet project deadlines. KonigFrankstahl received the HSS based on CON-A’s specifications in full bundles from ArcelorMittal Tubular Products Iasi to its warehouses in Bucharest and Sibiu and was able to deliver the material in the exact quantities, even cut pieces, to the different requested locations.
Three main factors convinced KonigFrankstahl to opt for ArcelorMittal products:
- the quality of the products, supported by certificates
- ArcelorMittal’s ability to ensure just-in-time delivery
- excellent communication with ArcelorMittal
Moreover, the collaboration with ArcelorMittal Tubular Products Iasi was very good due to the high support provided from production to logistics despite the high pressure regarding deliveries.
The Craiova stadium, inspired by modern art
The Craiova stadium located in the city of Craiova has a capacity of 30,000 seats and replaces the former Ion Oblemenco Stadium built in 1967. The new stadium was designed by the architects Dico and Tiganas architecture and engineering who took inspiration from the work of art “Mademoiselle Pogany,” carved by Romanian sculptor Constantin Brancusi. The iconic building offers a modern touch that will boost the development of the local area.
The building envelope has an elliptical shape, which protects the spectator seating area against adverse weather conditions while ensuring that the natural light hits the pitch and closes the secondary spaces under the stands. The volume of the bowl is enhanced thanks to the semi-open roof and the structural "ribs" wrapped with transparent and translucent materials.
The Targu-Jiu stadium comes into line with UEFA standards
Work at the new stadium in Targu-Jiu (in the south of Romania) is nearing completion; the tribune roofs are partially mounted, as well as the two scoreboards. The project involves the reconstruction of the Targu-Jiu Stadium to make it more modern and in line with the UEFA standards. Once completed, the stadium – which should be officially named Pandurii Arena - will have 12,500 seats and will also include an underground car park and a 40-room hotel. In the near future, the area around the stadium will enter into a modernisation process.

The Peking: Our beams secure a legendary 100-year-old ship
At the beginning of the 20th century, the 115-metre-long, four-masted ship Peking was one of the largest and most technically advanced ships in the world. Built as a steel barque for overseas trade in 1911, it could transport 5,300 tonnes of cargo and sailed 34 times around Cape Horn. The construction method used at that time made the ship very robust and reliable. The hull is made of steel and it could withstand more wind and adverse weather conditions than other ships.
The Peking spent the last few years as a museum ship in New York before heading back to Germany in July 2017. It will soon join the German Port Museum, but before that, the crucial challenge is to breathe a new life into this historic vessel.
Standing securely thanks to our beams
The Peking will stay about a year and a half in a dry dock to be renovated. The dry dock was built with twelve 16-metre-long HL1000 sections (with a height of more than one metre) produced by ArcelorMittal Europe – Long Products in Differdange (Luxembourg), which will ensure that the ship stands securely during the entire renovation period.
The beams were chosen due to the Peking’s high dead weight and the narrow space in the dry dock. These beams have a very high load-bearing capacity and a relatively low height. ArcelorMittal is the only steel producer who regularly rolls HL1000 sections. This is a key advantage in the project business as customers depend on reliable delivery.
Back to 1927
Following the decision by the German Bundestag in 2015, the federal government will pay the total costs of 120 million EUR for the repatriation, restoration, and fitting of the berth in Hamburg.
When the renovation is completed, the Peking will be brought back to its 1927 state. The underwater hull, the floor, the wooden deck, the rigging, and the interior fittings will all be renovated. Afterwards, the Peking is expected to be on show from 2020 onwards. Its future berth in Hamburg has not yet been decided; the “50er Schuppen” opposite the Elbphilharmonie is under consideration.
Steel gives a new life to German bridges
Last year, German magazine Der Spiegel published an article about the collapse of old bridges in Germany - mostly due to heavy vehicles traffic - and the efforts made to reconstruct and modernise them. The reconstruction of the bridge "Demminer Strasse" in Neubrandenburg with ArcelorMittal beams shows that steel is an ideal bridge solution, providing a sustainable, quick and economic construction.
Composite solution for more resistant structures
To rebuild the bridge "Demminer Strasse" in Neubrandenburg, general contractor Matthäi Bauunternehmen Leezen opted for a filler beam deck solution. This kind of steel-concrete composite bridge is used for short and medium span superstructures with severe construction depth restrictions. The new two-span bridge has two separated decks for each traffic direction. It is built over railway tracks and provides further connections via the B96 road.
As ArcelorMittal Downstream Solutions successfully collaborated with Matthäi Bauunternehmen Leezen for a precedent bridge project in Schwerin, we won the contract in May 2016 and delivered H-profile wide flange beams in grade S355M with a profile depth of 900 mm each. Due to the closely spaced beams and prefabricated fibre-cement elements, which are placed on the lower flanges, no additional formwork or falsework for the concrete between the beams was needed. Thus, traffic interference below the new bridge was strongly reduced and expensive closure times for the railway line could be limited to only few nights.
Sustainable beams from Luxembourg
The 19 and 31-metre-long beams were produced by ArcelorMittal Europe – Long Products' mill in Differdange (Luxembourg). Afterwards, they were cut and welded with transversals (IPE 400 S235JR) by Downstream Solutions in Bad Oldesloe (Germany). The thermomechanical rolling process of the high quality S355M grade associated with the anti-corrosion coating applied on the beams will ensure the longevity of the structure.
The beams, like most of our steel beams used in bridge construction, were made of scrap. This once again demonstrates the sustainability of steel, which can be recycled infinitely many times while retaining its properties.
Downstream Solutions and ArcelorMittal Europe – Long Products coordinated their deliveries with the customer and Deutsche Bahn, ensuring that assembling of the beams could take place at night in July without any problems. The construction of the bridge will be completed in the first or second quarter of 2018.
