What is a space frame?
Sphere, tube and bolt: three parts that make a space frame
A space frame is a three-dimensional lattice roof in which steel tubes meet at spherical node connectors. Straight members and pin-jointed nodes work together, so the load is not carried in one direction but shared by the entire structure.
That is why space frame systems are far lighter than conventional roofs and perform well in earthquakes; with the right geometry and structural design they can clear spans of up to 100 metres as flat roofs and up to 200 metres as barrel vaults without intermediate columns. They can be shaped as pyramids, cylinders, ellipsoids and arches, or as flat, multi-layer and folded forms.
What is a space frame? Read the guideAnatomy of a node connectionTap the parts
Sphere (node). Solid forged steel. Every member meets here; the threaded holes are CNC-drilled to the angles in the design.
Bolt. A high-strength bolt transfers the force from the tube into the sphere.
Sleeve nut. The hexagonal sleeve is turned with a spanner and drives the bolt into the sphere.
Pin. Locks sleeve and bolt together and shows how far the bolt has engaged.
Cone. Welded to the tube end; it channels the force from the tube down to the bolt.
Tube. The member of the system. Diameter and wall thickness follow the force it carries.

Why choose space frame systems?
Beyond the cost advantage, a space frame lets you use the space in the most efficient way: it removes the columns, carries the services inside its depth and changes with the building when your needs change.
Fast fabrication and erection
Components are prepared in the factory; on site there is only assembly. The programme becomes noticeably shorter.
Column-free, flexible space
Columns disappear from the floor plan; the area can be arranged freely and rearranged later.
Any geometry
From flat grids to domes, from barrel vaults to free forms: every geometry you can imagine can be built.
The right surface protection
Connection parts are galvanised; tubes, purlins and rafters are painted or otherwise protected according to the project.
Service-friendly
Electrical, ventilation, HVAC and plumbing runs pass through the lattice; luminaires hang directly from the nodes.
Economical transport
Light, knocked-down members take little space, so freight costs stay low — also for export.
Demountable and reusable
The bolted system can be erected in any season, dismantled and rebuilt somewhere else.
Geometry
Space frame forms
Whatever the architectural idea, there is a space frame layout that carries it. Pick a form and watch the structure change.
Flat double-layer grid
The most common and most economical space frame. Top and bottom chord layers are tied together by pyramid modules.

Shaqra University, Saudi Arabia
A stainless chrome-finish space frame for the courtyard and atrium roofs and circular rooflights of the Shaqra University campus. The wide courtyard between the building wings is covered by a space truss roof on tall columns; vertical lattice walls along the façade and the rooflights in circular openings were left exposed with their bright finish. The components were manufactured in Türkiye and shipped to site.

Where are space frames used?
Wherever a wide span, low weight and speed are required, space frame systems are the first choice.
Process
How a space frame is built in 6 steps
From the first call to handover, every stage stays with the same team and the same responsibility.
- Step 1
Survey and budget quote
We listen to your dimensions and needs and prepare a preliminary quote with form and cladding proposals.
- Step 2
Structural design
The system is solved in a 3D model; every tube, sphere and bolt is sized by calculation.
- Step 3
Fabrication
Tubes are cut, cones are welded and spheres are machined on CNC equipment.
- Step 4
Surface protection
Connection parts are galvanised; tubes, purlins and rafters are protected by paint, electrostatic powder coating or, on request, hot-dip galvanising.
- Step 5
Shipping
Numbered members are bundled and reach the site by truck or container.
- Step 6
Installation and handover
Our crews erect the system, carry out the checks and hand it over with its cladding.
Where we work
Space frames from Türkiye to the world
We take on space truss projects in every province of Türkiye, from Istanbul and Ankara to Izmir, Antalya, Samsun and Mardin. Abroad, we have completed projects in Turkmenistan, North Macedonia, Qatar, Egypt, the United Arab Emirates and Saudi Arabia.
We also provide design, fabrication, shipping and site supervision for investments in Azerbaijan, Kazakhstan, Russia, Iraq, the Gulf countries and Europe. Thanks to their bolted, modular design, space frame components reach any country in standard containers.

Frequently asked questions about space frames
What is a space frame?
A space frame is a three-dimensional, lightweight and rigid roof structure formed by bolting steel tubes to spherical node connectors. It is also called a space truss or space structure and is used to cover long spans without columns.
What are the advantages of space frame systems?
They remove columns from the interior, reduce foundation and transport costs thanks to their low weight, and are erected quickly. The modular parts can be dismantled and reused, and services and lighting pass easily through the lattice.
Where are space frames used?
Airport terminals and aircraft hangars, shopping malls, stadium and grandstand roofs, exhibition and congress centres, factories and warehouses, bus terminals, sports halls and swimming pools, mosque domes and petrol station canopies are the main applications.
How is the cost of a space frame per m² determined?
The price depends on the span, roof form, load conditions (snow, wind, earthquake), member sections and tube diameters, surface protection, type of cladding and the site location. That is why every space frame is quoted individually.
Is a “space roof” the same as a space frame?
Yes. “Space roof” and “space roof systems” are literal translations of the Turkish term uzay çatı. The established engineering terms are space frame, space truss and space structure — all describe the same tube-and-node roof system.
How long does a space frame last?
A correctly designed space frame with galvanised connection parts and tubes and purlins protected for their environment serves for decades. Maintenance needs are low: periodic visual checks and, where necessary, bolt torque checks are sufficient.
