On 30.08.2008, the city of Shanghai was provided with another striking symbol by the inauguration of the World Financial Center in Pudong business district. With a height of 492 m and 101 floors, the building became, at that time, China’s tallest building and the third highest in the world. This distinctive feature takes the form of an trapezoidal aperture through the top of the building. Here, at the dizzy height of 472 m, on the 100th floor, is the world's highest viewing platform.
The building features a concrete core, with four mega columns at the corners, linked to one another by truss belts and by bracing elements. Dillinger Hütte GTS supplied for this structure around 23,000 t of heavy plate ASTM A 572 Grade 50 and DI-MC 460 in thicknesses up to 100 mm. Steels with special deformation properties in the thickness direction (Specification Z25) were also used in specific cases, in order to assure the necessary high flexibility of the structure.
