Bolt balls are core connecting components in grid structures. They connect steel pipes through high-strength bolts, realizing fast assembly, precise positioning and stable force transmission, which is widely applied in large-span buildings like stadiums and workshops.
Bolt ball connections excel in strong load-bearing capacity, adapting to complex force conditions. Their modular assembly reduces on-site welding, shortening construction period. Good interchangeability lowers maintenance costs. They resist environmental corrosion well, ensuring structural durability in diverse scenarios.
The roof grid structure of a municipal stadium adopted bolt ball connections. 860 bolt balls connected 1200+ steel pipes. On-site assembly took only 28 days, 40% faster than welded structures. It withstood a magnitude 6 earthquake and has operated stably for 15 years.
If you’ve worked on steel structure construction or maintenance, what challenges have you run into when using bolt ball connections? And what specific fixes or improvements do you think would address those issues?
