Pre-stressed Pipes

The prestressed concrete pressure pipe has a composite design which allows the use of a low quantity of high tensile wire to sustain high working pressure and external loads

Using few steel, the pipe can be very economical


Resistance to corrosion thanks to steel passivation by concrete and low permeability of the concrete.

Internal diameters from 400mm to2000mm

This Bonna Pipe is complying with EN 639-642
