Suit the customer’s wishes

Close coordination with customers is vitally important to KELLER. After all, it's about adapting the existing systems to suit the customer's wishes and to design them precisely and efficiently. In this way KELLER creates practical innovation and sends out a clear quality signal.

Apart from the visual experience, the feel is also a major factor for the user's emotion. The most important questions are: What are the contour, surface structure and weight like, how do the fittings, the locks, etc. work?
