Three production companies form SMI Manufacturing. We work on high-quality metalworking at locations in Dokkum and Leeuwarden (The Netherlands). With years of experience and knowledge, extensive machinery and skilled employees, we distinguish ourselves in quality and diversity: from small to large machining, from sheet metal to heavy construction work. SMI Dokkum, SMI Van der Ploeg and SMI Plaatwerk jointly form a broad metal working division at the heart of SMI Groep. SMI Manufacturing works in close collaboration with the divisions SMI Maritime and SMI Security.
