Hans-Jürgen Behncke founded the Behncke Elektro-Stahlbau company in Putzbrunn. In a storage building, the inventive businessman developed various products up to series production, and soon acquired a reputation as a legendary innovator. In time, the company offered a wide range of products from household goods to oil burners, retractable garages and camping trailers. During the next few years, the utility products that initially were in high demand quickly turned into industrial products. Since then, the Putzbrunn factory has been manufacturing with utmost care, with the best source materials and top quality.
