The well-established flange supplier from the Siegerland region
After being founded back in 1934, Kiel Flanschen initially focused on developing to become a specialist manufacturer and flange supplier. As a provider of a comprehensive range of high-quality standard, special and customised flanges, our company went on to establish itself as a reliable supplier in many different industries.
