Company Tradition & History


Optimism comes from within.

As family-run company we are future-oriented by experience.

Margarete and Heinrich Diehl established a small art foundry, which expanded to a leading industrial company for semi-finished products within a few years. Their son Karl Diehl created a worldwide leading technology enterprise.

Recognizing the signs of the time the company's strategy switched to diversification just a few years after the establishment. Diehl Metall focuses on variety and uses the strategic synergies of the five Corporate Division of the Diehl Group. We are optimally positioned with 14,000 employees and thus, we will support our customers and partners as experienced problem solver - with curiosity and inquiring spirit.
