Although our products are rarely visible, you encounter them every single day. You benefit from their various functions and you touch them unknowingly. In order to ensure the reliable function of doors, windows and gates, the best quality fittings are required. We develop and produce all necessary components to provide high-quality door, glass and window technology. We advise and provide our customers with fittings for use in connection with steel or aluminium profiles – whether it may be a standard or a project-related solution for facades.


From concept to certified product, our team develops the best possible solution according to your needs. Through experience gathered from facing former challenges and through qualified advice, we help our customers realise their vision, from an initial idea to the final implementation of the product. All stages of production are concentrated at our site in Heiligenhaus, ensuring our product quality from A to Z.

The components of these solutions are ideally matched and thus add up to a high-standard that clients can trust.
