Advantages of the Hollow Bar Corrosion Protection System

In order to extend the service life of hollow bar, it can be dealt with corrosion protection. The corrosion protection system provides the design engineer and the owner with the possibility to easily and permanently protect tension members against corrosion. In particular, the following advantages are evident:

1. Applicable with new tension members or with tension members that are already in use
2. The hollow bar's corrosion protection system is based on the DENSO corrosion protection technology that has been successful for decades
3. The hollow bar's corrosion protection system is proved during tests at the material testing
4. The quality assurance according to ISO 9001
5. Robust multi-layer system with a layer thickness of at least 2,6 mm
6. Elastic properties which can support deformations of the tension member without damages
7. Any irregularities in the surface of the tension member are filled
8. Good adhesion of the hollow bar corrosion protection tape on the surface of the tension member
9. Positive impact on the behavior of tension members in rain-wind-induced vibrations, achieved through helical application of the corrosion protection tapes
10. The hollow bar can be dealt into different colors.
11. Simple and competitive assembly through the wrapping method especially developed for this purpose
12. No enclosure, scaffolding or other equipment such as working platforms or lifts are required
13. Short assembly time as no waiting time and curing time must be respected between the application of the several layers
14. Widely independent of weather conditions during assembly. A dry surface is the only precondition
15. Ecologically friendly assembly due to the omission of blasting works
16. No flaking or tearing of the wrapping, e.g. after a possible emission of cable filler at full locked cables or at relative displacements between single wires of the cable
17. Easy visual control for damages on the corrosion protection surface
18. Damages can easily be repaired by wrapping an additional layer of tape
