Overview
About Treschnak GmbH
Who we are
The firm Joh Treschnak was founded in 1978. She pursued from the beginning a two-pronged strategy based on metal products according to customers' drawings on the one hand and thermoplastic injection molded parts on the other. In line with the growing demands in the metal-processing area of our machinery has been steadily expanded. The Ter Steege Groep 2003 took over its long-standing Liferanten and supports the company in their current business fields in full. By moving to the new factory buildings at the site Zollhausstraße 5 in 2004, the company also equips spatially for future requirements For more info you like to see at our presentation.
