Guangzhou Xiaoman Waist is Guang Zhouta. The total height of Guang Zhouta building is 600 meters, of which the main tower is 450 meters high and the antenna mast is 150 meters high. It has the characteristics of super-high structure, strange shape, complex shape and the most steel consumption. Its outer frame tube is composed of 24 steel columns and 46 steel oval rings, forming a hollow and open unique body, which seems to be twisted and transformed in three-dimensional space. As the building with the thinnest waist (the smallest diameter is only more than 30 meters) and the most difficult construction in the world, the builders have overcome the unprecedented difficulty of engineering construction, accurately installed more than 10,000 inclined steel members with different sizes and specifications into towering architectural classics, and created a series of &”;the best in the world&”; in architecture.
