The One World Trade Center (1WTC), which was formerly named Freedom Tower, is currently under construction on Ground Zero in the very heart of New York, the place where the World Trade Center was destroyed on September 11, 2001.
A new landmark is currently being built in New York: the One World Trade Center. The corners of the skyscraper’s facade will be edged with stainless steel made in Germany. ThyssenKrupp Nirosta, Krefeld, produced the material using a customized rolling and heat-treatment process. A Cologne based partner company fabricated this high-quality material into complex facade elements for the corners of the One World Trade Center - some 250 t in total. After shipment to the USA, the installation work of these elements just started.
These 1 by 4 m facade elements are made of the corrosion-resistant stainless steel X2CrNiMo17-12-2, material number 1.4404. The textured finish was specially designed for this building.
Work on the project began in 2006. The high-rise itself will be 417 m tall, topped with a 124-m antenna. The total height of 541 m corresponds exactly to 1776 feet, a reference to the year the American Declaration of Independence was launched. Adjacent to the tower will be a museum and memorial to the victims of September 11, 2001.
The final architectural design of the building now under construction was drawn up in the New York office of the international architectural firm. The outer facade of the skyscraper will be made of glass. Above the 60-meter-high base, the metal frames surrounding the glass panes will be clad with stainless steel panels. The outstanding architectural feature of the design is that the edges of the building rotate through an angle of 45° from the base upwards. All the corner elements, therefore, have to be made in a tapering form in line with this axial rotation.
