The company was founded in 1964 by Dipl.-Ing. Wilhelm Gronbach.
Originally entrusted with the design and manufacture of hinges, the site underwent rapid technological development.
In 1985, Dipl.-Ing. Wilfried Gronbach took over the company in the second generation and developed Gronbach into a global player.
Under Dr. Lina Gebhardt-Gronbach, Gronbach has developed into a premium provider of high-end products as of 2017.
The locations in Italy and Slovakia were renamed “Gronbach”. Furthermore, all locations were transferred to a cross-functional group of companies as “One Gronbach”.
