MMK launches production of unique Russian flat steel with innovative coating

Magnitogorsk Iron and Steel Works (PJSC MMK) has launched the production of flat steel products featuring an innovative corrosion-resistant coating based on a zinc-aluminum-magnesium (Zn-Al-Mg) alloy. The production technology for this unique steel product was developed by the Scientific and Technical Center of PJSC MMK in collaboration with specialists from the Chief Rolling Department.

Flat steel with the new alloyed Zn-Al-Mg coating offers enhanced durability, reliability, and cost efficiency for steel structures and components. Notably, the zinc-aluminum-magnesium coating with 80-class corrosion protection properties has outperformed conventional 275-class zinc coatings in testing, enabling a reduction in coating mass while extending the service life of final products and structures.

These properties make the new coating particularly suitable for use in the construction industry—including light steel framing systems—as well as in automotive manufacturing and agriculture. PJSC MMK’s innovative Zn-Al-Mg coated steel represents a comprehensive and guaranteed solution that ensures product longevity and delivers cost savings throughout the full life cycle of the customer's finished goods.
