The final steel beam was placed atop the Shanghai Tower, making the structure China's newest "tallest building" and a standing testament to the country's construction frenzy.

Designed by US architecture firm Gensler, the dragon-shaped tower is the final skyscraper in the Lujiazui financial district's high-rise trilogy — along with the Shanghai World Financial Center and Jin Mao Tower.

Although the project is not yet completed, it was topped out on Saturday at 580 meters after nearly five years of construction. It will soar to 632 meters, and is scheduled for completion by 2015.

China's highest building, and the second-highest in the world, is surpassed only by Dubai's Burj Khalifa, which stands at 828 meters.

To distinguish itself from its high-rise neighbors that solely provide space for offices, dining, shopping, hotels and entertainment, the tower is to be built into a cultural community.

The skyscraper's developers also have announced an agreement with Ma Weidu, founder and curator of the Guanfu Museum, to open a branch on the 37th floor.

"The construction is like a vertical city," Gu Jianping, general manager of the Shanghai Tower Project, was quoted as saying by news website Eastday.

Apart from Shanghai, other cities have also started planning or constructing mega- structures.

Another high-rise planned for Wuhan may also challenge for the title of tallest. Shanghai developer Greenland Group has set an initial target of 606 meters, but that may increase, according to media reports.
