Engineering Production

Engineering production division deals with production of mechanical assemblies and equipment, piece and small batch production and renewal of spare parts for heavy industry mainly steel making industry, mining industry and related segments.

The division ensures machining, production of gearing, heat treatment, millwright and bridge building work, fabrication of steel structures and welded pieces. Production is carried out on the basis of the drawings provided by the customer or prepared by us.

Our experience in the field of engineering production enable us to implement turn-key capex projects starting with preparation of a design, drawing documentation, production and assembly, including implementation of partnership disciplines of hydraulics, electrical and civil engineering work.

Parts of engineering production:
