Be inspired by the advantages of plastic pipes


Plastic pipes have a potential useful life of more than a hundred years.


Production is much less intensive in terms of energy, as with other materials.


They are lightweight and thus cause fewer emissions during transportation as well.



The raw material allows for a wide range of applications.



Environmentally friendly installation methods and a wide range of connection options facilitate use.



They do not corrode and have high chemical resistance.


Abrasion resistant

Abrasion causes microplastics. Our pipes, on the other hand, have a very high abrasion resistance.



They are sustainable because plastic can be recycled relatively easily.



We have enormously high quality standards, secured by a large number of certificates.

Value for money

The price-performance ratio for plastic pipes is very good.

Focus on customer needs,
quality as a matter of course.

Genuine appreciation, real cohesion, above-average commitment.

Firmly rooted in Sprockhövel,
at home in international markets.

Long-term success instead of short-term profit.

Internally driven, sustainable and future-oriented,
in all facets.
