Structural Steel Roof Truss Systems

‌

1. Optimized Long-Span Architectural Solutions

   ‌Engineering Overview‌
   Steel roof trusses represent the pinnacle of efficiency in modern wide-span construction. Engineered for spans up to 150 meters, our systems utilize hollow structural sections (HSS) and high-strength friction-grip bolts (Grade 10.9) to achieve weight-to-span ratios 35% superior to conventional alternatives. All designs comply with AISC 360 and Eurocode 3 specifications, with optional seismic reinforcement meeting ASCE 7-16 requirements (R=6.5).

   ‌Technical Superiority‌

   • ‌Material Integrity‌: S355-S460 steel grades with Charpy V-notch impact tested at -20°C
   • ‌Precision Fabrication‌: CNC-cut node plates (tolerance ±1mm) and robotic welding (AWS D1.1 Certified)
   • ‌Corrosion Protection‌: Dual-stage surface treatment comprising hot-dip galvanizing (86μm per ISO 1461) and optional PVDF coating

   ‌Performance Metrics‌

   • ‌Load Capacity‌:
     • Dead Load: 0.5kN/m² (self-weight optimized)
     • Live Load: 1.2kN/m² (snow/wind combo)
     • Ultimate Wind Resistance: 75m/s (wind tunnel verified)
   • ‌Deflection Control‌: L/400 maximum under full service load
   • ‌Thermal Efficiency‌: 0.5% linear expansion coefficient (20-100°C)

   ‌Design Flexibility‌
   Our parametric modeling capabilities support:

   1. Multiple truss configurations (Warren, Pratt, Fink, or custom geometry)
   2. Integrated service provisions for MEP systems and skylights
   3. Pre-engineered connection details for hybrid steel-concrete structures

   ‌Quality Assurance‌

   • Third-party inspected dimensional reports
   • Material traceability per EN 10204 3.1 certification
   • As-built BIM models (Revit/LOD 350 & Tekla)

   ‌Project Implementation‌

   • 98% prefabrication rate minimizes on-site labor
   • Bolt-up erection methodology (3-7 days typical)
   • Full lifecycle maintenance protocols available
