The PTG Principle: Continuous quality management.

Security. Security. And security again.

We can’t take a joke when it comes to quality and security. Our observant members of staff meticulously detect any potential error.

For our clients this means 100 percent control in view of functionality and life cycle. And since we really can’t take a joke when it comes to security, we perform these controls based on optical and mechanical criteria.
You can count on it!

Controls. Controls. And controls again.

When you rely on PTG, you rely on severe quality control by independent institutions.

For our clients, this means:

And you can be sure that all agreed prices are fixed prices.
This is also part of our concept of reliability.
