About us

Whether standard or special requirements, WSS not only develops and produces hardware solutions for doors and windows such as self-locking panic locks, aluminium door hinges, 180° opening and concealed turn-and-tilt fittings or all-glass door fittings, but also meets architectural requirements for modern building functionality and appearance with solutions for
the façade.

WSS hardware solutions that have to meet specific requirements can also be found on oil rigs, ships and in rail vehicles.

In all applications of door hardware, WSS is the right contact for structural metalworkers, planners, architects and building owners.

The higher the demand for reliable, safe, sophisticated technology, the more important the dialog with the WSS team.

WSS develops system solutions with and for the decisionmakers around the technical building equipment. 

The aim of the WSS team is to offer WSS customers and partners added value. WSS – your partner on the way to the best solutions.
