This is why, at our production sites, we work according to globally valid quality principles:

• We manufacture our cable covers and cable protection conduits according to the valid state-of-the-art directives and standards.
• Our company is certified according to DIN EN ISO 9001:2015.

Certification according to ISO 9001 is the best known and most widely accepted quality management system. It confirms the quality capability of our company.

For the continuous enhancement of our products and processes, we work in close scientific exchange with the plastics technology institute (KTP) at the University of Paderborn.


Our cable protection conduits according to DIN 16874 are certified and externally monitored by the Darmstadt materials testing institute (MPA).

Our energy management system for improvement of energy efficiency is certified by GUTcert.

As a member of the DIN, we influence normative policy decisions and actively shape German standardization policy.
