Space Structure vs. Truss, H-Beam, and Concrete: Which Roof System Wins?

-

 Choosing the right structural system is not just a technical decision—it’s a strategic one. Below is a practical comparison between space structures and other popular systems used in large-span buildings.

Structure Type Max Span Weight Aesthetic Install Speed Cost Efficiency
Space Structure 30–150m+ Lightweight  Stylish  Fast (bolted)  High (prefab)
Steel Truss ≤60m Medium  Bulky  Slower  Moderate
H-Beam + Purlins ≤40m Heavy  Basic  Welding-heavy  High labor
Concrete Structure ≤25m Very Heavy  Plain  Long time  High cost

Key Advantages of Space Structure:

  • ✅ Long Span, No Middle Columns

  • ✅ Faster Erection with Bolted Connections

  • ✅ Architectural Freedom: Domes, Curves, Grids

  • ✅ Lower Foundation Loads = Less Concrete Needed

  How to choose suitable grid structure coal bunker roof building materials? Choosing suitable grid structure coal bunker roof building materials requires comprehensive consideration of many factors. In terms of strength and stability, high-strength steel, such as the Q355 series, should be preferred. This type of steel has a high yield strength and can effectively withstand the huge pressure generated by the accumulation of coal in the coal bunker, ensuring that the grid structure does not deform or collapse under long-term heavy loads. Its good toughness can also adapt to possible impact loads and ensure the safety of the roof. Corrosion resistance is crucial. There are coal dust, water vapor and possible harmful gases in the coal bunker environment, and the material is easily corroded. Hot-dip galvanized steel is a good choice. The zinc layer can form a protective barrier on the surface of the steel, isolate air and moisture, and delay rust. For coal bunkers near coastal areas o...

Steel grid is gaining more and more attention in green buildings, mainly because of its environmental and sustainable advantages: High strength and light weight: The grid structure can cover the space with a large span, reduce the use of columns, improve the efficiency of building space, and save materials. Recyclable: 100% of steel is recyclable and reusable, which is in line with the core concept of "sustainability" of green buildings. Short construction period: The components are prefabricated in the factory and installed quickly on site, which effectively reduces dust and noise pollution and has little impact on the surrounding environment. Strong compatibility with solar energy/green roofs: Steel structures are easy to integrate green building technologies such as solar panels and rainwater collection.

 Educational facilities must be built fast, last long, and adapt to future needs. That’s why more universities and schools are turning to space structures for their sports halls, auditoriums, and lecture centers. 1. Clear Spans for Multi-Use Halls No internal columns means more freedom for: 🏀 Basketball courts 🏸 Badminton arenas 🎭 Drama performances 🎓 Graduation ceremonies 2. Faster Construction = Less Disruption Space structures are prefabricated and bolted , allowing schools to finish builds during vacation periods or in parallel with academic schedules. 3. Durable and Safe Our structures meet international codes for wind, seismic, and crowd loads—ensuring student safety and long-term performance. 4. Light and Energy Efficient Add skylights or ETFE panels to reduce electricity costs. Some schools even integrate solar panels for net-zero goals. 5. Expandable in Phases Universities often grow. Space structures can be extended or retrofitted easily witho...
