About us

Galvanization ZGR Kovačić is a family-owned company founded in March 1982 as a small galvanizing workshop with 2 employees.

Over the years, due to market demands, we have adopted new technologies: glossy tin, duplex nickel plating,  chemical nickel plating, decorative chrome plating, silver plating, etc.

Since 1998 we have been conducting regular electrolyte analyzes in our own analytical laboratory in order to maintain and increase the quality of our services.

In 1999, through our own efforts and research, with the help of specialized suppliers, we developed the demanding technology of chemical nickel plating as well as the technology of electroplating on aluminum and Al alloys.

In 2002, a new line for the production of high quality demineralized water was put into operation, which significantly increased the quality of our services.

2003 and 2004 were marked by significant investments of our own funds in the construction of a new high-capacity line for nickel plating, decorative chrome plating and tin technology, as well as investments in waste water technology by purchasing a new filter press and a modern WATROMAT low temperature galvanic sludge dryer.

In 2016, we implemented ISO 9001: 2015 and 14001: 2015.

Our own quality testing laboratory is equipped with devices for measuring thickness:

Galvanotest 3000

Coulometer ElektroPhysik Galvanotest 3000


ElektroPhysik MikroTest 6G / NiFe50

XRF device Oxford X-Strata 920

Over the years, Galvanization ZGR Kovačić has profiled itself as a workshop that follows customers’ demands for quality, which we achieve by monitoring trends in the field of galvanic protection  and through continuous research and improvement through work and professional literature.

The business policy is the use of modern, environmentally friendly chemicals and technologies from the world’s leading renowned manufacturers. ZGR Kovačić employs 30 employees, and more than 90% of our services are exported outside Croatia.

Salt chamber ASCOTT 450

Also, as one of the few galvanizations, since 2019, we own salt spray chamber for testing the corrosion resistance of processed goods according to DIN and ISO standards.
