Spiral Concrete Corrugated Post Tensioning Tube Application

Post tensioning tube used in bridge industry

Post-tensioning tube in the concrete Floor

Corrugated tube used in building

Corrugated tube used in equipment base

Spiral Concrete Corrugated Post Tensioning Tube • For Apparatus Foundation
On many construction projects like apartment buildings, parking garages, office buildings, industrial buildings, bridges and docks, and schools and hospitals, the introduction of the prestressed protection tubes will make it possible to use very long spans. The reduction in weight allows large areas and fewer columns, which in turn will give technical economical and esthetic advantage.

Spiral Concrete Corrugated Post Tensioning Tube • For Bridge
The products are enlaced with 0.35mm thickness galvanized steel. They are widely used in bridge construction. Advantage: Low resistance, easily used in steel strand.

Spiral Concrete Corrugated Post Tensioning Tube • For Floor
With its special corrugations, the very high radial stiffness is well suited for use as former in concrete structures. Corrugated tube is also being used as culverts and forms for concrete projects, plinths and columns.
