WRW: Manufacturer and development partner

The production of multilayer composite pipes – this business idea proved to be a hit from the very beginning.

Founded in 2004, we now employ over 100 people and produce more than 60 million linear meters of high-quality products for building services and industry every year. We have thus established ourselves as Europe’s leading OEM manufacturer of multilayer composite pipes.

Today, WRW has a material, joining and process competence that is unique. This is the reason why, in addition to our standard products, our customers also take advantage of our expertise in developing specific solutions. For even better support, WRW offers its customers the dual qualification of manufacturer and development partner.

As a medium-sized, non-corporate company, we have the necessary flexibility to respond to our customers’ requirements and also offer many services related to the product that add value.
