Product Features of High-Speed ​​Rail Station Space Frames

1. Large Spans and Column-Free Spaces: Creates expansive and open interiors within high-speed rail station buildings and waiting halls, thereby enhancing the overall passenger experience.

2. High Redundancy and Strong Seismic Resistance: As a spatial load-bearing system, the space frame structure inherently possesses high structural redundancy; it is designed to withstand seismic intensity levels of up to Grade 8.

3. Factory Pre-fabrication and Modular Assembly: All structural components are fully pre-processed at the factory, allowing for direct on-site bolt connections or welding, which significantly shortens the installation timeline.

4. Lightweight and Steel-Efficient: Saves 15%–20% more material compared to traditional truss structures, thereby reducing both material consumption and overall project costs.

5. High Compatibility and Integration:Seamlessly integrates with various ancillary systems, including roofing systems, suspended ceilings, maintenance catwalks, and curtain wall connection nodes.
