Part of the secret of our continuing success is that all AK products, especially standardised products, have been produced through intensive collaboration with customers.

This continues to be AK trademark today. As a matter of course, all our products are tested and inspected to the highest standards within the company, including any extra tests and specifications required by the customer.

Some of our product groups undergo tests that conform to the DIN ISO performance standards and are certificated by TÜV Südwest.
