The Bolt Ball Space Frame Connector System is a high-precision structural connection solution specifically designed for modern steel space-frame projects requiring durability, efficiency, and dependable long-span performance. Engineered for demanding commercial, industrial, and large-roof applications, this connector system integrates bolt-ball spherical nodes with universal conical interfaces, forming a reliable three-dimensional structural network that ensures exceptional rigidity and load transfer efficiency.

As the core connection component of a space-frame, the bolt-ball joint plays a crucial role in transferring axial forces from tubular members across the entire grid structure. Our bolt-ball connectors are manufactured using high-strength steel and precision machining to guarantee superior accuracy and alignment during assembly. The spherical geometry of the bolt ball minimizes installation errors while enabling stress to be distributed evenly in all directions, which significantly enhances the stability and safety of the overall structure. This makes the system ideal for buildings requiring wide clear spans, such as exhibition centers, logistics warehouses, aircraft hangars, coal yard covers, gymnasiums, and architectural landmark roofs.

To accommodate various project requirements, the system supports circular hollow steel tube members in multiple diameters and thicknesses. The conical connector interface ensures compatibility across standard space-frame configurations, including square pyramidal systems, double-layer grids, and tri-circular arch shells. The result is an adaptable node-to-member connection that can be customized in size, orientation, and geometric arrangement depending on the engineer's design specifications. Whether your project needs a flat roof grid or a complex curved shell, the bolt-ball system provides the flexibility and strength required for long-term structural reliability.

Durability is further guaranteed through advanced anti-corrosion coating options. Each connector can be finished with an epoxy zinc-rich primer, anodizing treatment, or customized coating system designed to withstand harsh weather, humidity, and industrial environments. These protective layers extend the lifespan of the connector and help maintain structural integrity even under continuous exposure to wind, dust, or temperature fluctuations.

Installation efficiency is another major advantage of this system. Space-frame components are prefabricated off-site, enabling rapid on-site assembly. Depending on project scale and site conditions, installation can be performed using high-altitude assembly, block lifting, or the sliding construction method—particularly effective for extremely large spans. This modular approach minimizes construction time, reduces labor requirements, and ensures consistent assembly quality.

In addition, every bolt-ball connector adheres to international and national structural design standards, including CE certification, ISO9001 quality management, and major steel-structure codes. This ensures that the product not only meets engineering performance requirements but also complies with global building regulations, making it suitable for overseas construction markets and cross-border engineering procurement.

The Bolt Ball Space Frame Connector System is engineered for a design service life of 50 years, providing peace of mind for long-term project operation. With customizable material grades, surface colors, connector dimensions, and compatible tube sizes, this product can be tailored precisely to match the demands of engineering consultants, contractors, and steel-structure fabricators. Whether you're constructing a new landmark facility or upgrading an industrial roof system, our connector system offers a dependable, efficient, and cost-effective solution for any large-span space-frame project.
