The need for precise geodetic measurements for the determination of deformations of structures placed in facilities of black metallurgy is a great challenge for every geodetic expert. The very specific way of carrying out this type of measurements is related to the special conditions for their performance, as well as the need to ensure high accuracy in the determination of deformations on the structures. In the concrete case, deformations are obtained by processing highly precise optical measurements on the basis of which all further alignment and on-site machining activities were planned for supporting the process of hot rolling mill stand housing windows refurbishing and its evaluation for misalignment improvements. With this paper, the members of the Chair of Advanced Geodesy at the Faculty of Civil Engineering in Skopje want to demonstrate the universality of the geodetic deformation measurements and the concrete application in determining deformations of the mill stand which is an industrial plant with special significance for the production capacities of „Makstil” SC – Skopje.
