Abstract. In this paper the images of steel microstructures (on elements taken from ribbed bars were rolled using QTB technology) have been presented. The observation has been carried out on two types of steel which are most commonly used for ribbed bars, 34GS, BSt500S and 16, 25 mm in diameters. The observations on the structure of materials have been performed on samples perpendicular and parallel to the rolling direction (after surface nital etching). The analysis of a macro- and microstructure gave the possibility to approximate the causes of non-conformity of finished products, as a major problem in ribbed bars production and processing.
