Top 10 tallest steel buildings in the world

According to the Council of Tall Buildings and Urban Habitat, a steel “steel skyscraper” is one whose main construction vertical and lateral structural elements, as well as floor systems, are constructed from steel. The idea of steel skyscrapers was first fronted by Fazlur Khan, a vibrant young engineer of Bengali descent.

Although there are a number of incredible steel structures scattered around the world, these kinds of buildings are a phenomenon in their own right, relying solely on the brazen strength of steel for structural integrity.

Below we look at the top 10 tallest steel buildings to ever exist in the world.

1. One World Trade Center

One World Trade Center is the tallest steel building in the world. It is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. Also known as One World Trade, One WTC, the building’s steel structure topped out at floor 104, with a total height of 417 meters in August 2012.

The tower’s spire was completely lifted to the top of the building, also known as the Freedom Tower during initial planning stages on May 2013. This brought the total height of the tower to 541 meters.

In Nov 2013, the Height Committee of the Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH) announced that One World Trade Center was the tallest building in the United States. The committee claimed that the mast on top of the building is a spire since it is a permanent part of the building’s architecture.

2. Willis Tower, Chicago

Willis Tower

Also called the Sears Tower, Willis Tower was completed in 1974 having been constructed for just three years. Sears Tower stands 527 meters high owing to the extension of the western antenna in 2000.
