Hybrid Bolt Welded Connection Joint For Large Span And Heavy Load Public Buildings

Product Description​
A Hybrid Bolt-Welded Connection Joint is a high-efficiency and high-strength structural node solution that integrates the convenience of bolted connections and the rigidity of welded connections. This product uses 10.9 grade high-strength bolts to bear shear force and AWS D1.1 standard fillet welds to bear bending moment, working synergistically to improve node load-bearing efficiency by 30% compared to single bolted or welded nodes.​
One of the key features of this joint is its optimized force distribution—by assigning specific loads to bolts and welds, it reduces node size by 25%, making it suitable for large-span structures (gymnasiums, airport terminals) where space is limited. Customers can benefit from its high prefabrication rate: 80% of welding work is completed in the factory, reducing on-site high-altitude welding risks and improving construction safety.​
For enhanced adaptability, the joint reserves a ±10mm adjustment space, facilitating on-site correction of construction errors without reworking. Its load-bearing capacity is verified by professional load testing, maintaining plastic deformation ability under ultimate load to ensure sufficient safety margin. The surface treatment (hot-dip galvanizing for bolts, anti-corrosion paint for welds) ensures long-term durability in various environments.​
With its compatibility with large-span and heavy-load structures, this joint is ideal for gymnasiums, airport terminals, exhibition centers, and other public buildings. Whether it's for beam-column joints in large-span frames or truss-node connections in space structures, this product provides a compact and efficient solution.​
Customers can receive comprehensive technical support, including finite element analysis (FEA) of node force performance and on-site installation supervision. The team is dedicated to ensuring that the joint meets design expectations, helping customers achieve structural efficiency and project success.

Applications​
Hybrid Bolt-Welded Connection Joints are high-efficiency node solutions designed for large-span and heavy-load public buildings and industrial structures. Certified by ISO 9001 and AWS D1.1, they meet international quality standards, ensuring reliable performance in high-demand scenarios.​
These joints are widely used in gymnasiums, airport terminals, exhibition centers, large-span warehouses, and heavy industrial plants. Their compact size (25% smaller than traditional nodes) and high load-bearing efficiency make them ideal for structures where space and weight are critical, such as long-span trusses and cantilevered beam-column joints.​
The minimum order quantity is 3 sets for standard specifications, and customized solutions are available for bolt quantity, weld size, and node dimensions to match specific structural requirements. Competitive pricing and bulk supply discounts (for orders over 50 sets) make them cost-effective for large-scale projects, while the short delivery time (10-15 workdays for prefabricated components) supports tight construction schedules.​
With a monthly supply capacity of 5,000 sets, the manufacturer ensures timely delivery even for mega-projects. The service life of over 50 years, combined with dual anti-corrosion treatment, ensures durability in indoor and outdoor environments, including coastal areas and industrial zones with moderate corrosion.​
Customization options also include welding process optimization (for -10℃ to -20℃ construction environments) and anti-fatigue design for dynamic load scenarios (e.g., stadiums with frequent crowd movement). Whether it's for new large-span construction or old structure reinforcement, the Hybrid Bolt-Welded Connection Joint delivers efficient and reliable node performance.
