voestalpine Profilafroid designs and manufactures trapezoidal steel profiles designed specifically for orthotropic deck or deck bridges and more generally for the construction of steel platforms. Our profiles are up to 25 meters long, in one piece.
The cold rolled formed metal has a precise and constant production of the desired parts. The respect of dimensional tolerances, even weak, is undoubtedly the strong point of this technology.
The cold roll forming technique ensures the straightness of the bridges, a prerequisite for perfect welding of the deck.
The viaduct of Millau
Steel profiles of 21 meters long with a total weight of 8,000 tons, this is the technical contribution of voestalpine Profilafroid to the creation of this work of art.
The viaduct of Millau is a cable-stayed motorway bridge of 2,460 m in length, which spans the valley of the Tarn, to 270 m of height.Its metal deck weighs 36,000 tons, which is four times the weight of the Eiffel Tower.A technical and environmental achievement, the Millau Viaduct is 3 times the world record holder with the world's highest central pile, spire and deck.
