Our steel space truss structure is a lightweight, high-strength, and large-span spatial system widely utilized in large-scale public and industrial buildings. Leveraging premium steel tubes and professional fabrication techniques, our space frame structures are characterized by exceptional structural stability, uniform stress distribution, rapid construction, and superior durability. We provide comprehensive one-stop services-including custom design, production, installation, and after-sales support-to meet the diverse requirements of any engineering project.

Engineering Performance & Design Notes
This section explains how the space truss carries load and how it is checked, so you can specify it with confidence. Unlike a flat single-plane truss, a space frame is a three-dimensional lattice: every member and node acts in several directions, so loads fan out to multiple supports and stresses stay uniform across the grid.
3D uniform load distribution - force spreads to many nodes at once, keeping stress even and giving high redundancy.
Light weight, high strength - tubular members load axially, cutting steel tonnage versus an equivalent beam frame.
Seismic & wind adaptability - the multi-directional grid absorbs ground and wind input well in high zones.
Node design - bolted or welded spherical nodes sized by analysis; weld integrity verified by UT/MT.
Deflection serviceability - within L/250–L/300 for smooth spanning roofs and cladding fit.
Detailing - Tekla 3D lattice model issues member cutting, node and erection drawings.
Applicable design standards: AISC 360 · EN 1993-1-1 · GB 50017 (space-frame section) - selected per target market.

Core Advantages & Applications of Space Truss
Core Advantages
Ultra-wide column-free spanning - the 3D grid clears large bays without intermediate columns, maximising usable floor space.
Uniform stress & high redundancy - multiple load paths keep stresses even; the loss of one member does not immediately endanger the grid.
Less steel than a beam frame - axial-loading tubes save tonnage while holding stability for the same span.
Free architectural outlines - flat, curved, domed, spherical or irregular grids follow your design, not a standard catalogue.
Fast, durable construction - prefabricated flat-pack units assemble quickly and resist corrosion for a long maintainable life.
Applications
Stadiums & arenas - spanning roof grids over seating and pitch where stresses stay uniform across a wide canopy.
Exhibition centres & terminals - long column-free envelope and concourse roofs, often barrel-curved for drainage and light.
Industrial workshops - wide flat roofs for assembly floors with cranes and suspended services.
Daylight roofs & atriums - glazed flat-to-curved frames over skylights, malls and lobbies where a clean transparent roof line matters.

System & Geometric Selection
| Form | Best suited | Typical use |
|---|---|---|
| Flat space grid | Wide flat roofs & floor mezzanines | Workshops, warehouses, mezzanine decks |
| Barrel / curved | Long semi-cylindrical envelopes | Terminal concourses, exhibition halls |
| Dome / spherical | Concentric column-free coverage | Arenas, planetariums, atriums |
| Parallelogram / trapezoid | Irregular or angled footprints | Glazed & architectural daylight roofs |

FAQ:
What sizes of space truss can you build?
Space frames are engineered per project; typical modules span from tens of metres to 60 m+ column-free, sized after reviewing the bay layout and loads.
What is a spherical node space frame?
A three-dimensional grid in which tube members meet at bolted or welded spherical nodes, spreading load to many points at once for uniform stress and high redundancy.
Can you make curved, domed or trapezoidal shapes?
Yes - barrel, dome, spherical, parallelogram and rectangular outlines are all detailed in Tekla and shop-fabricated as one seamless grid.
Is it suitable for seismic and wind zones?
Yes - the multi-directional grid absorbs ground and wind input well when detailed to the local code.
Do you offer design, production, installation and after-sales?
Yes - one-stop cover from Tekla 3D design and fabrication to export packing; installation guidance is supplied with each delivery.
