Expertise, precision and flexibility

At SMI Groep, we believe that every customer deserves a perfect combination of expertise, precision, and flexibility. We are a family-owned business founded in 1980 by Jelle Jelsma and Gabe Spijksma, currently led by Spijksma’s sons, Bauke and Bert. What started as a simple machining and assembly department has grown into a leading player in the manufacturing industry of North Netherlands.

The three divisions of SMI Groep

SMI Groep consists of three divisions: SMI Manufacturing, SMI Maritime, and SMI Security, each excelling in their respective fields. SMI Manufacturing specializes in machining, welding, assembly, frame construction, and structural engineering. SMI Maritime provides smart solutions for (super)yacht and shipbuilding, bridging the gap between coast and ship. SMI Security offers security solutions for contraband detection.

SMI Groep aims to engage in meaningful entrepreneurship with a positive impact on people and nature. We explore opportunities to offer to individuals with limited access to the labor market and promote diversity in our workforce. We are increasingly producing energy-neutral and circular solutions.
