RK Rose+Krieger – How it all began

50 years of RK Rose+Krieger

In 2022 RK Rose+Krieger is celebrating its 50th anniversary. Established in 1972 as a manufacturer of industrial tube clamping systems, RK is now a leading developer and manufacturer of high-quality components and functional modules for automation and production applications, providing our customers with expert advice and a unique product range.

RK Rose+Krieger GmbH began by producing tube connection elements and tube system linear units. Almost ten years later, the patented BLOCAN® profile assembly system was developed as a module for mechanical engineering. Since 1987, the company has belonged to the global Phoenix Mecano Group, which specialises in the development and manufacture of niche products. Shortly after joining the Phoenix Mecano Group, the company moved to new premises in Minden, and the Hungarian production facility was commissioned. The products enjoyed such great success that by 2007 the buildings in Minden had to be extended.

Here is a chronology of milestones in our company history.
