Laboratories – comprehensive steel testing
We perform complete determination of mechanical, chemical and metallographic properties of steels.
Our laboratories hold an accreditation certificate according to the ČSN EN ISO/IEC 17025:2018 standard and are members of the Association of Czech Laboratories and Testing Laboratories (SČZL).
We regularly participate in interlaboratory comparison tests to ensure maximum accuracy, reliability and quality of results.
