The small/medium diameter pipe system dedicated to potable water applications available with diameters between 60 and 1000 mm. They are suitable for both transport and distribution of water in urban, semi-urban and rural areas.
Over time, the NATURAL range has imposed itself all over the UK and Europe, and it is at the heart of the networks heritage. Appreciated by pipe-laying contractors, they make installation easy. Identifiable by its blue colour, the NATURAL pipe benefits from BioZinalium® external protection technology. BioZinalium® ensures very long durability in underground conditions.
 
The internal lining of the NATURAL range is composed of centrifuged cement mortar. It offers excellent hydraulic conditionsas well as aneffective protectionagainst the aggressiveness of the water, NATURAL fittings are delivered with a blue epoxy coating, applied by cataphoresis or by powder coating.
