In the paper, the production requirements of the flat-oval steel profile in chosen production plant was presented. Process capability and its adjustment for the production of a chosen batch of oval profiles was described. Analysis of process stability for three different dimensions of profiles was conducted. On the basis of the Pareto chart, groups of problems, which have the biggest influence on the finished product, were determined. Two the most important causes, which generate about 53% of all nonconforming product, were pointed out.Keywords: Oval steel profile, capability factors, Pareto chart
