Steel Space Frame vs. Truss & Rigid Frame: Which Roof System Is Right for You?
Introduction When planning large-span buildings, choosing the right structural system is key. Here's how steel space frames , trusses , and rigid frames compare in terms of design flexibility, materials usage, construction speed, and cost. Strengths & Highlights Steel Space Frames – Outstanding load distribution across three dimensions—exceptional stability and seismic resilience. – Fast, modular assembly with factory-made precision (like Lego™) . – Supports stunning architectural forms with minimal internal columns. Space Trusses – Highly efficient at handling long spans using minimal material through axial load strategies. – Flexible in form—works well for pitched or curved designs. Rigid Frames – Reliable for clear spans under ~90 m, using standard moment connections. – Simple to fabricate and quick to erect; great for industrial or retail use. Practical Guidance Choose space frames if your project prioritizes architectural expression, large span, and o...
