Purpose: Bimetallic bars which possess higher corrosion resistance and mechanical properties, it is the new kind of bimetallic bars which are better than standard bars. The bimetallic bars are more often applied in concrete construction. There are few methods which ensure a good strength of bimetallic layer bond. Hydrostatic extrusion, rotary rolling and explosive cladding are most often used methods. Design/methodology/approach: The simulations of the bar rolling in a three-high skew mill were carried out using the Forge2005® commercial program. Findings: The higher value of yield stress of the cladding layer does not produce the effect of "flowing down" of this layer over the core surface and it’s folding between the rolls. The use of non-corrosive steel on plating layer assures receipt on a high durability and esthetics bimetallic bars. Practical implications: Bimetallic bars are chiefly used in the building industry at production of concrete constructions, and as working elements in bridge building in aggressive environment. Originality/value: Production of bimetallic bars is very difficult. One from many problems during production bimetallic bars is assurance good strength of bimetallic layer bond. A theoretical analysis of bimetallic bar rolling in a three-high skew mill is presented in the paper and the distributions of stress and strain intensities in the bimetallic bar during skew rolling are shown.
