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 openness.

  • Opt for trusses when you need efficient long spans and moderately complex geometry.

  • Use rigid frames for efficient, cost-effective builds with standard forms and short to mid-span requirements.

Architect Insights

“Space frame distributes loads across 3D—making minimal material do more.”
— Industry analysis on structural efficiency.
“Rigid frames deliver large clearspan economy within typical building ranges (≤ 90 m).”
— Structural consulting note on frame benefits.

What are the advantages of steel over traditional concrete?

  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more f...

 Structure of the hangar The plane layout and height requirements of the aircraft hangar are quite special, which directly affects the structure of the hangar . Due to the large span of the hangar, the structural self-weight (mainly the roof system) accounts for a large proportion of the total load. If the structural self-weight can be reduced, significant economic effects can be obtained. The steel structure has the advantages of high strength, light weight, small component section, weldability, and relatively simple manufacturing process. Therefore, it is common to use steel structure as a roof load-bearing system in large-span structures. The space frame structure system has good strength and light weight, which can solve some problems that cannot be solved by the plane structure system. Space structures such as shell structure, grid structure, and suspension cable structure have been widely used as roof systems for large-span buildings. If you have a similar project to be buil...
