As a leading company in the plastics industry, we have been developing, producing and installing sophisticated customer-specific cladding systems made of plastic for applications in a wide range of industries including medical technology, railways, sanitary facilities and plant engineering, as well as other industrial sectors, for decades.


Our expertise in process engineering and system solutions makes us ideally qualified to respond to your individual needs and requirements and to design the optimum moulded part for your applications. From a simple blank through assemblies to complex total solutions, along with a range of technical and logistics services, we can take care of every step along the way, from the clarification of requirements to fully assembled system components.




Romay was founded 70 years ago and since then it has developed from a supplier of individual parts for use in sanitary facilities into a systems supplier. Following a major fire in Unterkulm, the production and administrative site was rebuilt on a greenfield site in Oberkulm in the Canton of Aargau in 1969, as the company headquarters of Romay AG. The opening of our modern plant in China represented a further important step for the company – this time into the Asian market.
