- Numbered packing, container-ready shipping
The fabrication process
- 01Tube cutting
Steel tubes are cut precisely to the net lengths in the fabrication schedule.
- 02Cone welding
End cones are joined to the tubes by gas-shielded arc welding and the welds are inspected.
- 03Sphere machining
The holes of the forged steel spheres are drilled and threaded on CNC machines to the design angles.
- 04Surface protection
Connection parts are supplied galvanised; tubes, purlins and rafters are protected with primer and paint, electrostatic powder coating or, on request, hot-dip galvanising.
- 05Inspection and marking
After length, thread and coating checks every member is labelled with its code from the erection plan.
- 06Packing and shipping
Tubes are bundled, spheres and fasteners are crated and dispatched by truck or container.
Surface protection
Surface protection is applied during fabrication, in the factory. Connection parts such as bolts, sleeve nuts and pins are galvanised. For tubes, purlins and rafters the method is chosen for the project and its environment: primer and paint, electrostatic oven-cured powder coating or, on request, hot-dip galvanising. These are different processes: hot-dip galvanising protects the steel with a zinc layer, while electrostatic powder coating gives a durable baked finish in the chosen RAL colour. In humid, chlorinated environments such as swimming pools the protection system is strengthened accordingly.
Built for export
The bolted, modular design makes space frames ideal for export: components take little room, load into standard containers and are erected in the destination country without welding. The components of our projects in Turkmenistan, North Macedonia, Qatar, Egypt, the United Arab Emirates and Saudi Arabia were produced in Türkiye and shipped to site. Freight, customs and delivery scope are set by the terms of the quotation / contract.
Space Frame Fabrication — Frequently Asked Questions
In which colours can space frame members be produced?
With electrostatic powder coating any colour of the RAL chart is possible. Our projects include white, grey, blue, yellow and orange systems.
Do you supply materials only?
Yes. Where the design already exists we manufacture the space frame components, deliver them with erection drawings and can send a supervisor to site on request.
How long does fabrication take?
Fabrication time depends on the member sections, the scope of fabrication, the surface treatment and the size of the project. Once the shop drawings are approved, a dedicated schedule is prepared for each project.
