Milestones in our history
It didn’t start in a garage. But with a small business for metalworking and metal processing, founded by Alfred Junior in 1957. It was the starting point for today’s JUNIOR Group, which in addition to MJ-Gerüst GmbH also includes Junior Kühlkörper GmbH, which manufactures heat sinks and precision components for the electronics and electrical industry.
Strong industry, strong family
The companies of the JUNIOR Group have been family-owned since their foundation and are among the largest owner-managed industrial companies at our home location in Plettenberg.
Since the beginning of the 1970s, MJ-Gerüst GmbH has specialised in the production of scaffolding and has constantly expanded its product range.
We are now one of the three strongest and leading scaffolding manufacturers in Germany.
