Prefabricated Tube and Coupler Scaffolding
The Tube and Coupler scaffolding system is ideal for temporary structures requiring high strength combined with considerable flexibility in use.
The Tube and Coupler system – SOCOME 1 brand is manufactured using certified materials and subject to rigorous quality control. The tubes are suitable for demanding applications; the different coupler types allow the structure to be adapted to the requirements of the construction site.
Strength and flexibility in use
The Tube and Coupler scaffolding system – SOCOME 1 brand is manufactured using certified materials and subject to strict quality control. The tubes have technical characteristics that make them suitable for demanding applications.
The system uses cold-formed couplers protected against corrosion by galvanising. Tightening is secured by T-head bolts. The combination of tubes and couplers allows temporary structures to be configured to suit different geometries and operational requirements.
