In 1923, Karel Bos opened the first workshop in Alkmaar in the Netherlands, hence the name of the company: (Karel) Bos + Al(kmaar). Since then, BOSAL has grown to become one of the leading innovators of the automotive and energy industries, contributing to shaping a cleaner future at every step.

Our history

BOSAL as we know it today remains a family-owned, Dutch-registered company with its headquarters located in Lummen, Belgium. After decades of steady growth, the company’s expansion into Europe and Africa during the ‘60s and ‘70s and further into Europe, NAFTA & South America in the ‘90s by opening several Original Equipment Manufacturer (OEM) industrial sites, it established itself as a major OEM player globally.


To offer its customers tailor-made solutions, BOSAL forged production and research partnerships and formed successful joint ventures with a number of leading industry players. In 2021, turnover is estimated at €400 million, which was generated by more than 2,500 employees supporting our mission in 17 manufacturing plants, 12 distribution centres and 7 R&D sites worldwide.
