Design office

Being very close to its customers, the technical hub, with its R&D and Design departments, is a driving force in the company, creates added value and provides you with advice and innovative solutions for mechanical, thermal, electrical, electro-technical, IoT, acoustic, testing, qualification & certification issues.

As part of our new product introduction and “design to cost” process, the technical and industrial project managers guide product developments to meet customer requirements. GROLLEAU is therefore able to develop and market both its own products and customer-bespoke ones, and guarantee their reliability.
