ArcelorMittal is making steel for One World Trade Center in New York City

Rebuilding Manhattan’s skyline

Our steel plants and workshops in the US and Europe are part of a major project to build a new landmark for Manhattan

ArcelorMittal is part of the project to build a new world trade centre for New York City, following the destruction of the twin towers in the 9/11 terrorist attacks in 2001.

Our facilities in the US and Europe have contributed to the construction of a major new landmark for Manhattan, known as One World Trade Center – or 1WTC – formerly the ‘Freedom Tower’.

In December 2006, the first steel columns for 1WTC – rolled out and delivered by ArcelorMittal’s mill in Differdange, Luxembourg – were installed at the building’s foundations at Ground Zero. ArcelorMittal Logistics Belgium delivered the columns, shipping the steel from the port at Antwerp to two sites: Camden on the US east coast and Sorel in Canada.

The development process for the steel beams took place at ArcelorMittal’s metallurgy department in Esch-sur-Alzette, also in Luxembourg and Differdange. The beams were made from recycled steel, weighing 730 pounds per foot and ranging in length from 30ft to 56ft for shipping.

“Luxembourg, one of the smallest countries in the world, is producing the biggest steel beams in the world. Everybody is very proud to be a part of this project for such an important building in America,” says Bob Manet, process engineer, ArcelorMittal Esch-Sur-Alzette.

Other types of steel for 1WTC have been made at other ArcelorMittal mills. Since 2007, ArcelorMittal’s facility in Coatesville, US, has supplied more than 10,000 tonnes of plate in various grades for the 105-storey tower.

The plate products have been made into girders to support the foundation of the building, the foundation for the subway system beneath the building, floor support girders and building antenna.

“Providing plate material for One World Trade Center has great significance to ArcelorMittal because our Coatesville facility provided material for the foundation and support beams for the original building,” says Ed Frey, general manager, eastern plate, ArcelorMittal USA. “The components supplied by Coatesville for the original tower were one of the few remaining structures left standing after the collapse.”

1WTC is expected to be completed in January 2013. The tower will be 1,776ft (541m) high, in reference to the year the US Declaration of Independence was signed.
