Tradition with the courage to innovate.

300 years of corporate culture are proof of the adaptability of the Julius Cronenberg Sophienhammer (JCS) group of companies. Because even though times have changed, the company sends a clear signal for the further development of products - and encourages people to dare something new.

JCS group

Responsibility plays the decisive role here. The Cronenberg family of companies is already in its tenth generation and faces the challenges of globalisation. Entrepreneurial skill, experience and the will to innovate are the key to long-term success.

Quality "Made in Germany" is no empty phrase for the producing companies. Produced sustainably and fairly in Germany, the products are the foundation for the company's success. Accordingly, investments in the German location Arnsberg-Mueschede are not shied away from. These also prove the sincere attachment to the employees.

Another guarantee for success: the portfolio of the JCS group of companies is broad and international. Automatic drop seals, attractive street furniture, well thought-out railing systems or people guidance systems are just a few examples of the diversity of the range.
