Oriental Pearl, the Shanghai Radio and TV Tower, stands in Pudong, Shanghai. The total height of 468m is second only to the Toronto Tower and the Moscow Tower, ranking third in the world and first in Asia. There are two giant spheres on the tower. 80m above the ground, 50m in diameter (under the ball), and 280m above the ground, 45m in diameter (on the ball). The envelope structure is a single-layer bolt ball node reticulated shell designed by the East China Architectural Design Institute, Changzhou Grid Factory. Construction. The spherical shell has a complex structure, requires high processing, and is difficult to install. The stem of the reticulated shell is made of a special weathering steel pipe specially made by Shanghai No.1 Steel Factory. Both ends of the rod are welded to the head of the cone and controlled and inspected according to the American Standard (AWS); the low carbon is welded on the bolt ball.
