The Council on Tall Buildings and Urban Habitat (CTBUH) recently announced the completion of the Ping An Finance Center in Shenzhen, China. The building at 599 metres is now officially the second tallest building in China and the fourth tallest in the world, behind only the Burj Khalifa, Shanghai Tower and Makkah Royal Clock Tower.
The Ping An Finance Center, designed by Kohn Pedersen Fox Associates (KPF), is located in the heart of Shenzhen’s Fuitan District. It contains over 100 floors of office space located above a large public podium, with a multi-story atrium providing retail, restaurants and transit options to the city and greater Pearl River delta region.
CTBUH described the form of the tower as a “taught steel cable, outstretched by the sky and the ground at once. At the top of the tower, the façade tapers to form a pyramid, giving the tower a prismatic aesthetic.” The form is further emphasised by eight composite ‘megacolumns’ along the building envelope that streamline the building for improved structural and wind performance, reducing baseline wind loads by 35%.
The building’s facade is one of the most innovative feature and uses 1,700 tonnes of 316L stainless steel, making the envelope the largest stainless steel facade system in the world. The specific material was chosen for its corrosion-resistance, which will allow the building to maintain its appearance for decades even in the city’s salty coastal atmosphere.
