Import Bolt Ball Space Frame Steel Structure — Buy in wholesale FOB from Supplier in China

The bolt ball space frame steel structure from Jiangsu Lijing Steel Structure Technology Co., Ltd. in Xuzhou, Jiangsu province, is a three-dimensional structural system where members connect through spherical bolted nodes. The bolt ball itself serves as the critical load-transferring component, manufactured from 45# steel with diameters ranging from 100 mm to 300 mm per GB standard. Each ball contains between three and twelve drilled holes, with every bolt hole axis passing through the geometric centre centre of the sphere to ensure concentric force distribution.

The 45# steel material (Chinese GB grade, equivalent to approximately 0.45% carbon content) provides the yield strength and toughness required for structural applications. Hole configurations vary by project: fewer holes for simpler trusses, up to twelve for complex intersection nodes in large-span roofs. The through-centre drilling ensures that axial forces in connected members resolve without eccentricity, a fundamental requirement for space frame stability. Surface treatment typically includes shot blasting followed by galvanising or painting, though buyers should confirm the specific finish offered by this supplier.

This structural system suits sports arenas, exhibition halls, airport terminals, and industrial plant roofs where column-free spans exceed conventional frame capabilities. Buyers include general contractors, stadium developers, and steel fabrication subcontractors. The modular nature allows site assembly with standard wrenches, reducing crane time compared with welded alternatives. Importers should verify whether Jiangsu Lijing supplies design calculations, node detailing, and installation guidance alongside the physical components, as these services vary among Chinese space frame specialists.

Jiangsu Lijing Steel Structure Technology Co., Ltd. maintains its registered address at Huarun Load, Xuzhou, 221005, Jiangsu, China, placing it within one of the country's densest concentrations of steel fabrication and heavy engineering capacity. The supplier holds a harbour trust tier, which represents an entry-level verification status on the platform. Notably, the listing shows a response rate of 0.00% and an average response time of zero hours, indicating that this supplier has not yet established a track record of replying to buyer enquiries through the platform. Buyers should treat direct outreach via the listed address or alternative channels as essential.

The company's profile focuses specifically on bolt ball space frame technology, suggesting specialisation rather than general steelwork diversification. The source description emphasises GB standard compliance and precise dimensional ranges for the bolt ball components, but does not state annual output, fabrication floor area, workforce size, or export experience. No certifications (ISO 9001, EN 1090, AWS welding) are mentioned. The absence of claimed clients, project references, or case studies means buyers must conduct independent due diligence on manufacturing capability and quality control before committing to volume orders.
