About us

Whether in cars, buildings, roads or household appliances - we develop pipes, shafts and system components made of plastic and metal that can be found almost everywhere. We have been working together as a strong team for over 110 years. The basis of our success is the experience and competence of our 5,000 employees at 21 locations worldwide.

Through research and constant innovation, we always set standards in the fields of building construction, civil engineering, automotive and industry. The basis for this are our key inventions: the flexible electrical installation pipe made of metal, its further development made of plastic and our yellow drainage pipe.

As a family business, we don't think in quarters, but plan for generations. Our goal is to offer our employees secure jobs and to leave a healthy company for the next generation.
