You rarely see our products, but you deal with them every day. You use them and touch them without knowing it. Quality fittings are essential for the proper functioning of doors, windows and gates. We develop and produce all the components required for the reliable operation of high-end door, glazing and window technology. We advise our clients and supply fittings for applications used in conjunction with steel and aluminium profiles either as standard solutions or building-specific façade solutions.


Our team works to produce the best possible solution from the product concept phase right through to the tested and certified product. It applies the experience acquired from many challenging projects and, drawing on the professional advice of a manufacturer, helps in the application of WSS technology. The production activities are all under one roof at our facility in Heiligenhaus, ensuring product quality from A to Z.

We are right in the middle of things.

As we are both developer and manufacturer, we are more than familiar with our products, their technology, their application options and how they all work together. We apply this knowledge and wide-ranging experience in an advisory capacity when meeting the requirements of investors, clients, planners, architects and general contractors on the one hand and system suppliers, processors, façade builders and metal workers on the other hand. The dialogue involving all decision makers and WSS expertise produces reliable technology for the best possible solution.


System solutions

We supply total solutions in which complementary products from other manufacturers have been incorporated to the same standard of technology and quality.  With access to these manufacturers, which reflects our technical expertise, and with direct access to the users, comprehensive system solutions are created in which all components are matched perfectly to each other and with which compelling concepts can be developed. WSS advises and delivers the tailored system solution, regardless of whether, for example, a lock has to be upgraded to a fitting system for a multi-functional fire door or a window fitting has to be expanded to suit a building-specific façade solution, a high-traffic fire door has to be incorporated into a building guidance system or a complex revolving door or sliding door system has to be embedded in an access control concept.
