Central Factory Laboratory

The Central Factory Laboratory of LLC "Tashkent Metallurgical Plant" is a key department for production. The CFL is responsible for the incoming control of hot-rolled coils, various solutions, and paint materials, as well as ensuring the quality of the produced galvanized steel and galvanized steel with polymer coating.

Accredited in accordance with the requirements of the international standard ISO 17025
- The laboratory is equipped with the most advanced equipment produced by global leaders:

himadzu, Walter + Bai AG, TQC, Elcometer, NOVOTEST, FUTURETECH CORP, Beijing TIME High. Technology Ltd, CYMC, BYK, Bruker AXS Q8 MAGELLAN, TESTO, X-RITE, PANTONE, Nikon, and others.

It has highly qualified personnel who have undergone training courses on testing and the competence of testing laboratories (ISO/IEC 17025).
- Modern testing methods are applied.
- The new laboratory premises meet all the requirements for environmental, sanitary-hygienic, fire safety, and safety standards.

The main tasks of the laboratory:

  • Quality control of raw materials and materials

    The laboratory conducts thorough analyses of incoming metals and components, ensuring their compliance with regulatory requirements and technological standards.

  • Technical control during the production process

    Regular testing at various stages of production allows for the timely detection of deviations and the prevention of product defects.

  • Research and development

    The laboratory actively participates in research activities aimed at improving existing technologies and developing new methods of metal processing.

  • Environmental control

    Constant monitoring of the impact of production on the environment, as well as conducting necessary analyses to comply with environmental standards.
