After the Austro – Hungarian compensation in 1867, Hungary starts to build up its own industry. In the year 1871,„Výsadná cisárska a kráľovská železiarska a banská spoločnosť Union“ („The Privilege Imperial and Royal Iron and Mining Company Union“), was established in Vienna, which establishes a factory for production of iron in Zvolen, on the junction of the rivers Hron and Slatina in the same year. The closeness to the railway station, sufficiency of water energy, a closeness of wood reservers and coal reservers in Badin are the reason for the choice of a placement of the factory. Zvolen was an important railway and road junction of the Upper Hungary.
