WE. ARE. JUNIOR.
The companies in the JUNIOR Group have been family-owned since they were founded and are among the largest industrial companies at our home location in Plettenberg.
Since the early 1970s, MJ-Gerüst GmbH has specialized in the production of facade and industrial scaffolding and has constantly expanded the product range. For example, what is probably the most advanced modular facade scaffolding on the market, MJ OPTIMA, is a development from Plettenberg. We are now one of the three strongest and leading scaffolding manufacturers in Germany.
Precision, flexibility, economy: This is what JUNIOR Kühlkörper GmbH has stood for since it was founded more than 30 years ago. Today the company is one of the leading manufacturers of high-quality precision components and aluminum heat sinks. It specializes in particular in the processing of individual extruded profiles for large outputs.
JUNIOR Kühlkörper GmbH and MJ-Gerüst GmbH produce exclusively at our home location in Plettenberg. Thousands of new items are created here every day and sold all over the world. While heat sinks are mainly used in the electrical industry, where they usually covertly ensure that sensitive technical components do not overheat, scaffolding systems from MJ from Plettenberg can also be found everywhere in everyday life. You just have to take a closer look: The new building in the neighborhood, the scaffolding around the church tower or on the bridge that is currently being renovated - all of these are SCAFFOLDING MADE IN PLETTENBERG.

Regardless of whether you are an employee, a customer, a business partner or simply interested in our group of companies: Simply download our myJUNIOR APP and become part of the JUNIOR family yourself!
