Foundation of the Rainer May GmbH: The industrial master craftsman Rainer May and his wife Renate hire three employees.


Construction of own production facilities at Neuwied. 


Construction of a further manufacturing facility. The first waterjet cutting system is acquired. Now more than ten employees work at the Rainer May GmbH. TÜV Rheinland certifies its quality management to the ISO 9001 standard - a certificate that has been renewed each and every year since then.


Transfer to a newly acquired manufacturing hall and administrative building with over 5,700 m2. Over 20 employees now work at the Rainer May GmbH.


The entire company building is equipped with a photovoltaic system. Every year, over 70,000 kilowatt hours are fed into the power grid. 


Our range of machinery expands with the first laser cutting machine.
