Spherical grid structure refers to the use of bolt balls and high-strength bolts as nodes, and design the spherical appearance of the grid building structure by designing the position of the bolt ball nodes. This kind of spherical node grid structure refers to the grid structure with bolt balls as nodes and steel pipes as rods, also called bolt ball grid structure. It originated in Xuzhou, Jiangsu. Therefore, spherical grid companies are concentrated in Xuzhou.

A long time ago, perhaps because the processing of balls was difficult, and high-strength bolts were not very common, there was a grid structure that used gusset plates to link angle steel and other members. After this structure appeared, everyone thought this thing was really great. In order to distinguish the previous structure, the latter one is called the ball node grid.

Because the development of the bolted ball grid structure in Xuzhou area determines that the spherical grid structure is in a leading position in the country and the world in terms of production technology and installation experience, so friends who have this need can learn about Xuzhou grid production enterprises.
