The following dimensions of ribbed bars are specified in the standards: nominal diameter and their permissible deviations, mass range of 1 m of ribbed bar, core diameter, rib height, width and length of ribs longitudinal. For individual steel grades, their chemical composition is also defined. The requirements regarding mechanical properties, plasticity and weldability are also specified. Complaints can be treated as one of the tools which gives a lot of information about product quality, even if they are often overlooked in the qualitative analysis. In complaints customers describe the problems they encountered. These problems and their causes should be analyzed and eliminated by the enterprise. Professional complaints management can be treated as an important element of the product quality improvement system. The enterprise not only adjusts knowledge about the quality of its products in this way, but also obtains feedback from customers about these products.
