FAQ

  • Ultramarin d.o.o. is the technological successor to IMGRAD. The expertise in GRP composites and surface protection, dating back to 1950, has been significantly upgraded since then. We have updated the engineering foundation from the era of the K67 modular kiosk with modern technologies, enabling much higher precision and compliance with contemporary industrial standards.

  • We are a development-oriented group with a strong regional footprint in Central and SE Europe. Our primary manufacturing and development facilities are located in Slovenia, supported by strategic subsidiary operations in Serbia and Bosnia and Herzegovina. This allows us to offer optimized logistics and competitive manufacturing for global partners.

  • The Ultramarin Group provides vertically integrated solutions for the Marine (luxury yachts and workboats), Automotive (emergency and light vehicles), and Agricultural Machinery sectors. We also provide specialized surface protection for the Construction and Architecture industries through our powder coating division.
