Mainstar GmbH is the German subsidiary of Maintec Technologie Co., Ltd. from Shanghai. We combine Chinese manufacturing capability with German quality standards and personal service.
Our office is located in the Mertons Mitte complex at Lurgiallee 10-12 in Frankfurt-Riedberg — a modern office building shared with institutions such as the BaFin (German Federal Financial Supervisory Authority).
From here we coordinate sales, customer service and logistics for the entire European market. Our own warehouse enables short lead times without dependence on third-party suppliers.
