THIELMANN GRAPHITE GmbH & Co. KG has been selling graphites and graphite products for more than 40 years, the main emphasis being on natural graphites. In 1982 the company moved into the premises of Becker Pennrich KG, which has also been working with graphite for more than 40 years, the focus being the processing of synthetic graphites.

As early as 1995, the quality management system was certified in accordance with DIN EN ISO 9001 by DQS (Deutsche Gesellschaft für Zertifizierung von Qualitätsmanagementsystemen mbH, or German Association for Certification of Quality Management Systems Ltd). To meet the exacting demands on the quality of the graphites that we supply, our own testing laboratory has numerous facilities for verifying quality as part of incoming and outgoing goods inspection.
