Rhine-Main is our home region. With warehouse and sales in Frankfurt we supply companies from Wiesbaden via Darmstadt to Hanau and Aschaffenburg — short distances, personal, just-in-time.
The Rhine-Main region is one of Europe's strongest economic areas — and far more than the financial center of Frankfurt. Chemistry and pharma in the Höchst industrial park, measurement and control technology, automation, medical technology, automotive suppliers around Rüsselsheim, plus energy and utility technology shape the industrial picture. Add an extraordinary density of mid-sized manufacturers.
For this region Mainstar is literally on site: warehouse, sales and project management are in Frankfurt, Lurgiallee 10-12. That means short distances, in-person meetings and just-in-time supply in the metro area — often same or next business day. Developed in Germany, manufactured in our own factory with laser soldering and 100% final inspection, delivered without middlemen.
Control-cabinet wiring and cable-chain-rated harnesses for machine and plant builders — EMC-shielded, >5M flex cycles.
Dense medical and pharma cluster — manufacturing per ISO 13485 with laser soldering and full traceability.
Assembled lines for photovoltaics, storage and heat pumps — EN 50618, IP68, 25+ years of design life.
