History

Rädlinger primus line GmbH is part of the Rädlinger group which has been active in the construction sector for over 40 years. Today, the company is one of the most successful construction companies in Germany whose expertise mainly lies in road construction, civil engineering and asphalt construction. 

From the Idea to Success

Primus Line® was developed to solve the recurring, time-consuming and costly problem of run-down pipelines in existing buildings.

Josef Rädlinger already had the idea of using a hose for civil engineering 20 years ago. The hose was to be characterised by flexibility, portability, light weight and low wall thickness, while having the material strength of a steel pipe.

Ten years later, with being open to new ideas, the know-how from the fields of construction, mechanical engineering and web technology were combined to find a creative and efficient solution. Together with research and industry partners Rädlinger experts developed the Primus Line® technology. This technology now sets news standards in gas ans liquid transportation.
