In 1907, Johannes Ahlmann's son Julius joined the Carlshütte. Julius succeeded his father as commercial director in 1919, and continued the successful modernisation course. However, he died of a serious illness in 1931. His widow Käte Ahlmann was determined to preserve the company's heritage for the next generation. In 1937, she succeeded in acquiring all the shares for the family, and transformed the public limited company into a KG. Käte Ahlmann took over the management of the Carlshütte, which from then on was a family business. In the same year, parts made of asbestos cement were produced for the first time. This gave rise to a concrete division.
