History of ArcelorMittal Zenica
1892
Iron and Steel Works Zenica was established
2008
2017
2018
Project Phoenix implementation - restart of integral route
125 years of steel production in ZenicaInauguration of the new production line for rebar in coil
Capital repair of Blast furnace – sustainability of integrated production for the next two decades
2004Acquisition by LNM Group, later ArcelorMittal
1992Development of the factory was stopped because of the war in Bosnia & Herzegovina (for the next 17 years)
1947-1958
Integral cycle of steel production was introduced
1988Steel factory produced 1.906.000 t of steel
REINFORCING STEEL
The manufacturing process of reinforcing steel with controlled cooling using TEMPCORE® technology ensures the production of high strenght reinforcement with improved adherence to concrete providing homogenous properties for construction of buildings, bridges, motorways and other concrete structures in any geographical area.
Advantages of rebar in coils in further straightening & bending provide increased productivity, improved yields, lower wastages, efficient inventory management, lower labor costs and faster application.
