Russian steelmaker MMK Group has announced that it has officially launched production of zinc-aluminum-magnesium (Zn-AlMg) alloy-coated rolled steel, becoming the first company in Russia to manufacture this next.generation product.
The Zn-AlMg coating offers enhanced durability, corrosion resistance, and cost-effectiveness, addressing theneeds of multiple industries, including construction, automotive, and agriculture.
superior corrosion protection compared to traditional zinc coating
In comparative testing, the new class 80 Zn-AlMg coating surpassed the performance of conventional class275 zinc coatings, enabling lighter coating weights, longer service life of steel products and lower maintenancecosts over time. This positions MlMK''s coated steel as a strong solution for steel structures exposed to high-humidity, industrial, or coastal environments.
Technology behind the Zn-Al-Mg advantage
The coating''s performance stems from the cathodic protection of zinc and the barrier effect of aluminum andmagnesium oxides. Together, these elements offer selfhealing properties for minor surface and edge damage.prevent rust and degradation and maintain high plasticity and hardness, ideal for formed and shapedcomponents such as automotive body parts.
The Zn-Al-Mg coating is also lightweight and recyclable, aligning with modern environmental and sustainabilitystandards.
