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

The ball space frame is a three-dimensional steel truss system assembled from multiple hollow steel members connected at spherical nodes, engineered primarily for long-span roof structures. Jiangsu Lijing Steel Structure Technology Co., Ltd. fabricates these systems using welded hollow section (WHS) members joined through bolted or welded ball nodes, with the specific steel grade, tube diameter, and wall thickness determined by project span and load requirements. The supplier's systems are designed for spans commonly ranging from 30 metres to over 100 metres, with dead load and live load capacities calculated per GB 50017 or equivalent structural codes.

The steel members are typically fabricated from Q235B or Q345B carbon structural steel, with surface treatment by hot-dip galvanisation or sprayed coating to achieve specified corrosion protection lifespans. Ball nodes are cast or forged from steel billets, machined to precise tolerances for member end-plate connection, and inspected for ultrasonic flaws per standard weld inspection protocols. Typical member specifications include circular hollow sections from 60.3 mm to 219.1 mm outer diameter, with wall thickness from 3.0 mm to 8.0 mm depending on force distribution in the grid. The modular grid pattern, commonly square or triangular on plan, determines the structural depth and overall stiffness of the completed frame.

Primary applications include sports hall roofing, theatre auditoriums, exhibition centres, railway station concourses, grandstand canopies, aircraft hangars, and industrial workshops requiring column-free internal space. Buyers are typically general contractors, stadium developers, municipal infrastructure departments, and industrial facility owners procuring through design-build or design-bid-build contracts. The supplier operates from Xuzhou, Jiangsu Province, with export capability subject to confirmation of fabrication capacity, welding procedure qualifications, and third-party inspection arrangements. Buyers should verify load-bearing calculations, seismic design parameters for their specific region, and corrosion protection specifications directly with the supplier before finalising technical submissions.

Jiangsu Lijing Steel Structure Technology Co., Ltd. is based in Xuzhou, Jiangsu Province, China, with its registered address at Huarun Load, Xuzhou 221005. The company holds a harbor trust tier on the platform, and its response rate is recorded at 0.00 percent with an average response time of zero hours, indicating limited or no response history through this channel. The supplier's profile does not disclose annual turnover, employee headcount, factory floor area, specific certifications, or named client projects, so buyers should request these directly during qualification.

The company's product focus is steel space truss structures, specifically marketed for roofing applications requiring long clear spans with minimal internal columns. Its source description emphasises advantages including light weight, seismic resistance, and architectural flexibility, though these claims should be substantiated with project references, third-party test reports, and engineering calculations during due diligence. Buyers should verify the supplier's welding procedure specifications (WPS), non-destructive testing capabilities, and quality management system certification before committing to production orders.
