Maintenance of industrial machines

GrappS a.d. has years of experience in maintenance of industrial plants. Seven years of renewed annual maintenance contract in US Steel Serbia is something that we are proud of. Primary position within the so-called "key players" gave us a privileged position to work with top experts in the field of metallurgy, mechanical engineering, project management and others.

Work on weekends, night shifts, working at height or in gas hazard zones is something that has become our everyday life. The experience gained in the steel mill, hot and cold rolling mill as well as the blast furnace in the steelworks enabled us to seamlessly adapt to oil refineries, mining complexes, cement and paper industry.

Some of the maintenance tasks in industrial plants that we have completed safely, with a high quality level and within the deadlines are:
