Spiral Concrete Corrugated Post-Tension Tubes

Description and Features of Spiral Concrete Corrugated Post-Tension Tubes:
Our spiral corrugated post-tension tubes are widely used in bridges, buildings, parks and gymnasiums. We have provided a patented invention series to meet the changing market. We have the ability to produce 2000 meters per machine due to the highly automated equipments.
Parameters of Spiral Concrete Corrugated Post-Tension Tubes:
Radial: even load, impervious
Axial: tensile
Bend: impervious
Applications of Spiral Concrete Corrugated Post-Tension Tubes:
Our corrugated tubes are widely used on many construction projects like apartment buildings, parking garages, office buildings, industrial buildings, bridges and docks, schools and hospitals, the introduction of the pre-stressed 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.

Characteristics of Spiral Concrete Corrugated Post-Tension Tubes (for bridges):
The spiral corrugated post-tension tubes that manufactured in China are enlaced with 0.35mm thickness galvanized steel. They are widely used in bridge constructions.
Advantage: low resistance makes it easy to be used in steel strands

Characteristics of Spiral Concrete Corrugated Post tensioning Tube (for floor):
Due to its special corrugations and a very high radial stiffness can make this corrugated tube better adapt to concrete structures. Corrugated tubes can also be used as culverts and forms for concrete projects, plinths and columns.
On many construction projects like apartment buildings, parking garages, office buildings, industrial buildings, bridges and docks, schools and hospitals, the introduction of the pre-stressed 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 advantages.
