Our History
From the first screws to holistic project execution
It all started in 1996 – with two doers, a clear vision and a healthy dose of drive. Over the years, a trading business for special screws grew into a company that today supports complete projects in special machine construction – professionally, in a structured way and with an eye for the big picture. We take responsibility seriously, yet remain down to earth. After all, anyone who wants to work reliably over the long term needs not only precision but also the ability to see things with a clear head and a certain degree of composure.
1996
Founded with foresight
By founding Stahlberg GmbH, Rainer Stahlberg and Oswald Metzen laid the foundation for a company that focused on quality, reliability and technical expertise from the very beginning. Both remain closely associated with the company as shareholders to this day.
1998
A home of our own
With the move into the new office and warehouse building on Dietrich-Bonhoeffer-Straße, the infrastructure grows – and with it the ability to coordinate larger projects independently.
2000
Growth through structure
With the introduction of the just-in-time logistics concept and a framework agreement with Siemens Energy Mülheim, Stahlberg develops efficient supply models for C-parts at an early stage.
A new inventory management system creates transparency, and with more than 20 employees the company grows into a new dimension.2002
Stepping out into the world
The first deliveries to the USA (Charlotte, NC) and Asia mark the beginning of international partnerships.
