Météor Building: A modern landmark thanks to the spangly look of ArcelorMittal metallic coated steel
Designed in one of the largest port cities on the Atlantic coast, the Météor Building bears witness to the economic vitality of the outskirts of Saint-Nazaire, France famous for its shipbuilding and fishing industry. The contemporary office complex is enveloped in facade panels made of ArcelorMittal’s metallic coated steel which ensures aesthetic quality and resistance.
A symbolic gateway
At almost 28 metres in height, the Météor towers have created a landmark for the regeneration of Saint-Nazaire.
Each building comprises seven levels of office space which is occupied by local and regional government departments. With a total of 1500 m2 of floor space, the towers can accommodate more than 400 people.
Metallic coated steel: Highly reflective...
The use of metallic coated steel cladding was specified by the project’s architects, Blanchard Marsault Pondevie. “We chose this coating because it is a material that plays subtly with the light as it constantly changes throughout the day and the seasons,” explains architect Jean-Claude Pondevie. “It has helped to create a building which is unique, unpretentious and very refined.” Around 3000 m2 of metallic coated steel was required to clad the two Météor towers, making them visible from a considerable distance.
Part of ArcelorMittal’s aesthetic range of flat carbon steels, this metallic coated steel offers a one-of-a-kind finish which is specifically tailored for modern and contemporary facades. With between 1000 and 1800 spangles per square decimetre, this makes the difference between a unique and a remarkable building.
... and remarkably long-lasting
The spangly look of this metallic coated steel comes from its alloy coating which is comprised of 55% aluminium, 43.4% zinc, and 1.6% silicon. This alloy combination ensures the sparkle will persist for many decades.
The steel also has outstanding resistance to corrosion, even in the highly corrosive maritime environment found in Saint-Nazaire. ArcelorMittal is so confident this coating's ability to withstand corrosion that for applications in the construction sector we back the AZ185 coating with a 25-year guarantee!
With the landmark Météor towers in place, attention has turned to the further development of the 30 hectare Villes-Gare site. Between now and 2020, the plan calls for the addition of housing and offices within a 400 metre radius of the railway station. All new buildings on the site will comply with the BBC (low-energy building) standard, which is now the standard in France.
