Quality Control / Third Party Certification

High product quality and reliability are guaranteed by the latest methods of control in material and practical testing.

To comply with the regulations of the international classification societies and relevant ISO standards is only the minimum certainty we are offering to our customers.

We ensure a superior performance of our propellers and shaftings by running continuous quality tests in our laboratory. Noise and vibration tests are carried out by own engineers as well during driving operation.

Our services and products are verified regularly. Have a look at the actual third party certifications below:
