Laboratory

We provide chemical analysis of materials, mechanical testing and metallographic analyzes of the material structure for internal purposes and for the needs of external subjects.  The laboratory provides its services to the extent specified by the customers and in cooperation with the manufacturing operations; if necessary, we are able to analyze and evaluate the samples in three shifts (continuous) mode.
