ArcelorMittal Steel at the heart of the pioneering structure of the new Bordeaux Stadium

23-10-2014



Presse release: It is the first time in France that a stadium has been built using such a large proportion of steel !

ArcelorMittal steel, manufactured in-the group’s French and European plants, is one of the principal materials used for the structure of the New Bordeaux Stadium, which will, notably, be a venue for EURO 2016. It features a structure that is unique in France, made of steel, renowned for its extreme lightness.

The use of steel in the structure of the New Bordeaux Stadium replaces the traditional and almost exclusive use of concrete and enables a significant reduction in the weight of the building. The weight saving results in a reduction in the foundations, enabling time and cost savings. The New Bordeaux Stadium will be built in 26 months, between January 2012 and January 2015.

For the New Bordeaux Stadium, ArcelorMittal has supplied:
- 4200 tonnes of steel beams
- 500 tonnes of steel tubes
- 70,000 m² of steel for the interior trim (including the giant perforated canopy in the Fréquence® profile; the canopy provides protection against the elements but also has a sound insulation function)
- 20,000 m² of composite steel floors (Cofraplus® 60)

Steel is present throughout the New Bordeaux Stadium:
- the structure of the North and South stands,
- the structural framework of the upper tier,
- the steel roof structure,
-  the majority of the cladding: the underside of the bowl of the upper terraces, the cladding of the serpentine mall, and all of the roof supports and roofcovering

 

The structural framework represents 12,000 tonnes of steel, twice the weight of the Eiffel Tower. It consists of 644 round steel columns up to 37 metres tall and the steel is used to support other materials such as the aluminium external cladding.
The frame was entirely fabricated in France, in particular from ArcelorMittal steels supplied from Spain.
As regards the cladding, manufacture was undertaken in the plants at Haironville (Fréquence®) - Hacierco® 40SR and 56S), Strasbourg (Cofraplus® 60) and Contrisson, where the new "Colorissime® Evolution" coating was produced to ensure more effective corrosion protection than that provided by conventional coatings.
The unique composition of this zinc-magnesium based coating, which enables the delivery of performance that is markedly superior to that of other solutions, is also more environmentally friendly because it increases the lifespan of buildings and reduces CO2 emissions by reducing product weight.
H. Bourrier, CEO of ArcelorMittal France, said: “ArcelorMittal is a major player in the construction sector due to its wide range of steel products and solutions used for both the building structure and the envelope (roof, facade, floor).
The Group also offers many innovations to satisfy this sector's new technical and aesthetic requirements.”

 

 

ArcelorMittal steel is increasingly present in the construction sector, where it replaces traditional, heavier, less strong and more expensive materials. ArcelorMittal steel is therefore found everywhere: in structural, cladding, facade, roofing, floor, composite insulation or integral roofing, in particular photovoltaic roofing, products for industrial, commercial, agricultural, and residential buildings.

ArcelorMittal steel has recently been used for the envelope of the Geoffroy Guichard stadium in Saint-Etienne, the construction of the Zenith concert hall in Rouen, the Perpignan recycling centre and the Quai des Arts centre for the arts in Rumilly…Steel is infinitely recyclable without loss of properties and 80% of steel from the construction sector is recycled in steel mills.

 

The maximum capacity of the New Bordeaux Stadium will be 42,000 seats in the football or rugby configuration, making it the only stadium with this capacity in south-western France. It was designed as a multifunctional venue to accommodate a varied programme of events - sporting, cultural and business. The New Bordeaux Stadium was designed by the Herzog and de Meuron architectural practice. Construction was entrusted to the Stade Bordeaux Atlantique consortium comprising two major players in the construction sector: the VINCI and FAYAT groups, including the latter’s subsidiaries Castel & Fromaget and Sarec.
