The project has 3 floors underground and 68 floors above ground, with a total construction area of about 150,000 square meters and a total building height of 338 meters.The total steel consumption is about 24,500 tons.The steel structure project started in 2001, originally designed as a concrete structure, and when the construction reached the 6th floor above ground, Hangxiao Steel Structure converted it into a steel frame support structure system, and the steel frame columns adopted rectangular steel pipe concrete columns, made of Q345C. This project was the first tallest building independently designed, manufactured and constructed in China at that time, and broke the technical barriers of China's previous super-high-rise buildings that relied on foreign design and raw material supply.This project was the first tallest building designed, manufactured and constructed independently in China at that time, breaking the previous technical barriers of China's super high-rise buildings relying on foreign design and raw material supply.The project won the China Steel Structure Gold Award.
