Q355B Q460 Prefabricated Assembly Splicing Joint For Fast Track Construction

Product Specification

Product Description​
A Prefabricated Assembly Splicing Joint is a modular and efficient structural node solution designed for rapid assembly of steel columns, beams, and trusses. Manufactured with Q355B/Q460 high-strength steel, this product features standardized interfaces with reserved connecting sleeves and bolt holes, enabling on-site rapid docking via high-strength bolts (10.9 grade) without on-site welding.​
One of the key features of this joint is its high prefabrication rate (90% factory completion), which reduces on-site construction time by 70% compared to traditional cast-in-place or welded nodes. The built-in positioning pins ensure alignment accuracy of upper and lower components within ±2mm, guaranteeing structural precision and stability. The modular design allows free combination of standard modules (3m×3m, 4m×4m), adapting to different building sizes and structural types.​
For enhanced durability, the joint surface is treated with cathodic electrophoresis (dry film thickness ≥80μm), providing superior corrosion resistance (salt spray resistance ≥1200 hours) and outperforming traditional spraying by 2-3 times. It is compatible with various steel section types (H-beam, box-section, I-beam), making it suitable for prefabricated residential buildings, temporary exhibition halls, industrial workshops, and modular commercial complexes.​
With its easy installation—requiring only ordinary tools and no professional welders—this splicing joint significantly reduces construction labor costs and improves construction safety. The detachable design also facilitates later maintenance, replacement, and structure expansion, providing flexibility for project lifecycle management.​
Professional services include BIM-based module design optimization, on-site assembly training, and quality inspection guidance. The technical team is dedicated to ensuring seamless integration of the joint with the overall modular structure, helping customers achieve efficient and cost-effective construction.

Applications
Prefabricated Assembly Splicing Joints are high-efficiency modular node solutions widely used in prefabricated and fast-track construction projects. Certified by CE (EN 1090-2) and ISO 9001, they meet international quality and safety standards, ensuring reliable performance in modular structural systems. These joints are suitable for diverse scenarios, including prefabricated residential buildings (steel frame modular houses), temporary exhibition halls and event venues, industrial workshops (rapidly built production facilities), modular commercial complexes (office buildings, retail centers), and prefabricated bridge segments. Their high prefabrication rate and rapid installation make them ideal for projects with tight schedules, while the detachable design supports structure expansion and relocation (e.g., temporary construction sites). The minimum order quantity is 5 sets for standard modules (3m×3m, 4m×4m), and customized solutions are available for module size, steel section compatibility, and connection strength to meet specific project needs. Competitive pricing and bulk purchase discounts (for orders over 50 sets) enhance cost-effectiveness, while the short delivery time (7-15 workdays for prefabricated modules) supports fast-track construction. With a monthly supply capacity of 3,000 sets, the manufacturer ensures timely delivery even for large-scale modular projects. The cathodic electrophoresis treatment and high-strength steel material ensure long-term durability in indoor and outdoor environments, including urban construction sites and industrial zones. Customization options also include high-seismic grade optimization (up to 9 degrees) for earthquake-prone areas and corrosion-resistant upgrades (fluorocarbon coating) for coastal modular structures. Whether it's for new modular construction or traditional structure renovation (modular expansion), the Prefabricated Assembly Splicing Joint delivers efficient and flexible node performance.
