Test procedures for top quality

We ensure the reliable premium quality of our products through comprehensive internal and external quality control. We firmly believe in the maxim: trust is good, but control is better.

Our test procedures include ultrasonic testing, strength and crack testing, and spectral analysis. We work closely with Germanischer Lloyd Prüflabor in Stuttgart, Germany. As a neutral, internationally accredited test institute, Germanischer Lloyd audits and documents the requisite quality of our products. This institute provides mechanical, metallographic and non-destructive material tests as well as test reports, examination of damage and inspection certificates 3.1C / 3.2 in accordance with the EN 10204 standard, and all that at short notice.
