Dear customers and partners,

For more than 55 years, RYB Group, French specialist in polyethylene tube and network system solutions, has grown through new products and services, increased its distribution in France and worldwide, and conducted various external growth operations that have both increased and diversified its activities.

As we have already informed you, RYB recently acquired the French subsidiary of the Polypipe group, one of the main European manufacturers of electrical, sanitary and ventilation pipe ducts. This is a new stage in the life of our company.

Hence, to make this new important stage in our development official, we wanted to give ourselves a strong new name within a unified organisation.

Our group has thus become:

This changes nothing in our daily relationships as our legal structures remain unchanged.

The newly constituted ELYDAN group is now positioned as:

  • One of the main European players in polyethylene solutions
  • With 7 factories in France and Belgium
  • Almost 400 employees
  • A consolidated turnover of more than €120 million
  • Operating in around fifteen countries

In a growing European building and civil engineering market, we focus on three areas of growth: innovation and new services, international development and investment in production tools and resources.

This new organisation for the ELYDAN Group gives you:

  • A wider range of products
  • Increased commercial and technical support, specialising in your methods and markets
  • Even greater customised support, responsive to your needs
  • More comprehensive services
  • Guaranteed quality for all our products

Commercially, ELYDAN Group’s activities are organised as follows:
