Gienanth is probably the portfolio company with the longest tradition: iron has been processed in Eisenberg/Pfalz, the foundry group's headquarters, since 1735. The site in Fronberg can be traced back to the year 1449. Today, the Gienanth Group with its six locations is one of the most efficient innovation leaders in the industry. The broadly diversified customer portfolio includes world market leaders who are supplied globally. In particular, the partnerships that have grown up with respected manufacturers of large engines form a stable basis for further growth.

About one third of the turnover is accounted for by cylinder crankcases for engine blocks, which are manufactured in the hand-mould casting process and are very demanding in terms of process technology. These are used as diesel, gas and hydrogen engines; gas engines in generators for decentralised energy supply (for example also in data centres for cloud applications) or as power supply or drive units on ships, locomotives and in other large vehicles. For such crankcases, Gienanth is the leading supplier worldwide. The company also has a leading position in another business area, machine mould casting. It produces highly stressed castings in large quantities, mainly clutch and brake components for the automotive and commercial vehicle industries.

The portfolio is rounded off by expertise in machining and providing ready-to-install system components - whether as individual parts or in large series.
