Hangxiao Steel Structure (HXSS) pioneered the rectangular CFST (Concrete-Filled Steel Tube) structure in 2000, breaking international technical monopolies through industry-university-research cooperation with top Chinese universities. This 3-hour fire-resistant steel framing delivers unmatched safety, economy and applicability compared to pure steel or concrete structures, while cutting overall project costs by 20%. The flagship product, Model HXSS-16, has been applied in landmark high-rise projects like Ruifeng International Commercial Building, a China Torch Program project that revolutionized traditional reinforced concrete construction. It supports 50+ story skyscrapers with superior seismic performance, and its advanced BIM-optimized design maximizes material efficiency and construction speed, making it a top choice for cost-sensitive, high-standard building projects.
Specification Item | Details |
Model Number | HXSS-16 |
Brand | HXSS |
Fire Rating | 3-hour |
Core Steel Grade | Q355B (≥355 MPa yield strength), S460M |
Seismic Performance | 9-degree (compliant with ASCE 7-22 standards) |
Maximum Clear Span | 18m |
Recycled Steel Content | ≥90% |
Prefabrication Completion Rate | 95% (factory-finished) |
High-grade steel materials enable 30%-40% lighter frameworks than concrete, while supporting super high-rises. Advanced BIM modeling optimizes load distribution, achieving 15%-20% material savings and cutting foundation costs by up to 25%. This advantage is crucial for vertical expansion projects seeking both performance and cost control.
95% factory prefabrication reduces on-site work by 6-8 months for 30-story buildings, with CNC cutting ensuring ±2mm tolerance to eliminate rework. This modular approach boosts construction speed by 35% compared to conventional methods, shortening project cycles significantly.
Equipped with Buckling-Restrained Braces (BRBs) and moment-resisting frames, the structure achieves 9-degree seismic performance, exceeding concrete’s energy absorption by 60%. Post-earthquake retrofit costs are 70% lower than traditional systems, enhancing long-term structural safety.
With over 90% recycled steel content, the framing reduces embodied carbon by 45% vs. concrete. Integrated photovoltaic-ready roofs and thermal-break cladding cut HVAC loads by 25%, facilitating LEED Platinum certification for green building projects.
18m clear spans eliminate interior columns, increasing rentable space by 12%-18%. Adjustable steel grids support 10+ layout reconfigurations over a building’s lifespan, enhancing long-term value for property owners and adapting to changing usage needs.
Ideal for hybrid residential-commercial towers with 18m column-free retail atriums, enabling 30% faster core construction and 15% higher ROI for developers. The product’s cost-saving feature aligns with high-rise project budget demands.
BRB-equipped frames ensure 9-degree seismic safety and ±5mm vibration control for MRI rooms, achieving 48-hour post-earthquake operational readiness for critical healthcare services. The3-hour fire rating adds an extra layer of safety for medical facilities.
Reconfigurable MEP grids support weekly tech upgrades, while 14m clear spans enable AI-driven hot-desking layouts, boosting occupancy efficiency by 30%. The structure’s flexibility adapts to modern office design trends.
95% factory-finished guest pods cut project timelines by 8 months, with acoustic-decoupled floors reducing noise between suites by 55dB and enhancing guest experience. The fire-resistant feature meets hotel safety standards strictly.
Self-inspection is conducted at every stage of design and fabrication to ensure compliance with international standards. Strict quality checks cover material selection, processing, and pre-assembly to avoid defects.
Third-party inspection is fully supported to meet customized quality requirements, providing clients with additional assurance of product reliability and performance.
Professional technical engineers are available to supervise on-site installation overseas, with successful projects in Iraq, Dubai, South Africa and other countries, ensuring smooth construction regardless of location.
We are a direct factory, so you can enjoy the most competitive price without middleman markup.
We implement strict self-inspection during design and fabrication, and we welcome third-party inspection to verify quality.
Yes, our professional engineers can supervise installation on-site in overseas countries, with rich experience in global projects.
Our products are widely sold to Europe, Africa, the Middle East, Southeast Asia, Australia, New Zealand, South America and other regions.
