ArcelorMittal helps get Saint-Etienne’s ‘chaudron’ EURO 2016-ready


Press release :

Saint-Etienne’s Geoffroy Guichard stadium in France is receiving a new skin. As it gets ready to host matches of the EURO2016 football championship, our Trapeza® and sidings ST 500 from Arval by ArcelorMittal steels are providing the stadium with a new, shiny armour.


  The ‘Chaudron’ (French for caldron), as the stadium has been known since 1974 has been modernised seven times since its inauguration in 1930.

This latest modernisation which began in 2011 is set to be the most exciting yet for sports and architecture enthusiasts alike.

The make-over will not only extend the capacity of the stadium from 35,600 to 40,000 seats but will also provide the stadium with a distinct, eye-catching silhouette setting it apart from the rest of France’s many stadiums. Parisian architecture firm Chaix & Morel Architectes designed a semi-transparent envelope made of ribbed, perforated metal sheets which allows light to filter through. Our Arval roofing and cladding solutions were chosen by the architects to create this visually innovative facade.

The Chaudron is one of France’s ten stadiums which are all being revamped in preparation of EURO 2016.

Built in 1930, the ‘chaudron’ was always different from other stadiums. Unlike other football stadiums in France, the Chaudron was built ‘the English way’; i.e. in a rectangular shape and with four seating terraces that stand alone and are not connected with one another. When the decision was taken to refurbish the stadium, the Saint-Etienne community insisted that while the image of the stadium should be enhanced, the distinctive features of the stadium should remain the same. Opting for our steel solutions will allow architects and the construction company to do just that.

In order to meet technical requirements, Chaix & Morel are going to cover each of the four terraces in new, arch-shaped wraps and will add three outer shells to fill the gaps between some of the terraces to bring the stadium’s capacity up to 40,000 seats.

These outer shells use Arval’s trapezoidal steel profiles from Haironville.Trapeza® 5.180.44 BPT  with a Krystal® metallic coating( Aluzinc) is used both on the outside and inside of the shell and Pre-lacquered Hairplus® steel blades sidings ST 500 from Cérons are also used in the structure. A special perforation was applied on the steels, to fully meet the architects’ requirements.

In total, 12,000m2 of ArcelorMittal Construction cladding as well as 16,000m2 of Hacierco pre-lacquered roofing products are being used in the stadium. Being built in three different stages, completion of construction on the stadium is expected in November 2014.
