As a critical load-bearing component in prefabricated modular buildings and cast-in-place concrete structures, the steel reinforcement truss is fabricated by welding together top chord bars, bottom chord bars, and web bars using specialized equipment, forming a truss structure with a stable triangular cross-section. Thanks to its optimized mechanical load-transfer path, it can effectively resist bending moments and shear forces generated by horizontal elements such as floor and roof slabs—while significantly streamlining on-site construction processes. This approach seamlessly integrates factory-based prefabrication with rapid, on-site assembly. Widely used in various types of projects—including residential buildings, industrial plants, and public structures—the product plays a pivotal role in enhancing construction efficiency and ensuring superior structural performance, making it an essential building material for modern construction practices.

Core Product Advantages

• Outstanding optimized load-bearing performance: Featuring a triangular truss structure design, this approach efficiently transfers bending moments to the top and bottom chords while allowing the web members to handle shear forces. Compared to conventional random reinforcement layouts, this innovative design boosts structural load-carrying efficiency by more than 30%. Moreover, the coordinated action of the top and bottom chords along with the web members effectively controls member deflection, significantly enhancing the floor’s crack resistance.

• Factory prefabrication boosts efficiency: Fully automated production lines enable mass prefabrication, eliminating the cumbersome on-site rebar tying process. On-site construction now involves only lifting, positioning, and assembling, reducing the construction time for horizontal components by 40% to 60%. This approach also cuts down on the need for on-site rebar workers, thereby lowering labor costs and minimizing management risks.

• High stability and controllability of quality: In the factory’s standardized production environment, critical parameters such as rebar spacing, weld quality, and truss dimensions are precisely monitored throughout the entire process, eliminating quality fluctuations caused by on-site manual operations. Each production step undergoes rigorous quality inspection to ensure consistent product quality.

• Adapts to prefabricated construction needs: Seamlessly integrates with precast elements such as composite slabs and profiled steel sheets, creating a unified assembly system. Lightweight and easy to lift, it is ideal for high-rise buildings and large-span spatial structures, reducing reliance on heavy lifting equipment.

• Customized adaptation to diverse scenarios: Supports tailoring truss products with varying heights, spans, and rebar grades based on design requirements such as project span, load capacity, and member thickness. It can also accommodate multiple construction methods, including cast-in-place and precast/assembly, meeting the demands of a wide range of engineering projects.

Application Scenarios

Procurement and Usage Guidelines

1. Procurement Instructions: When placing your order, please provide detailed design drawings, clearly specifying the truss height, span, diameters and grades of top and bottom chord as well as web members' reinforcing bars, seismic resistance requirements (indicated by "E" or not), construction method (cast-in-place/precast), and the quantity required per batch, to ensure precise customization for production.

2. Storage Guidelines: Products must be stored separately in a dry, well-ventilated indoor area or under a rainproof shed. They should be placed vertically on dedicated racks or neatly stacked (stacking height ≤1.5m) to prevent deformation due to excessive pressure. Different product specifications must have identification tags clearly indicating the model, batch number, and design parameters.

3. Construction Requirements: Strictly follow the design drawings and construction specifications during lifting operations, ensuring uniform truss spacing and secure anchoring. When integrating with concrete, ensure thorough compaction of the concrete pour, fully covering the upper and lower chord reinforcement with a protective layer thickness that meets design requirements. During lifting, avoid collisions to prevent weld cracks.

4. Quality Traceability: Each batch of products comes with a Certificate of Quality, Weld Inspection Report, and Original Material Warranty, detailing information such as truss specifications, mechanical properties, weld strength, and production batch. Before construction, please verify that the parameters match the design requirements.
