3rd generation at the head of the company

The story begins in 1950 with the creation of FERONYL by Mr. Liévin DEDECKER. To respond as closely as possible to customer demands in terms of quality and cost, he bought out his bar turning subcontractor Vandenbosche and appointed one of his sons, Patrice, to head the company. It was in 2017, after having held various positions in family businesses, that Bruno DEDECKER took over the management of the company.
He is committed, with all of his employees, to preserving and developing the intrinsic values of the company: high quality, innovation, flexibility, proximity, confidentiality and efficiency.
“To innovate is to build together in the mutual respect and trust of our customers and our teams”
