Russian steelmaker NLMK Group has announced that it has begun testing its zinc, aluminum and magnesium coating (ZAM) for cold rolled products. Compared to regular zinc coatings, ZAM makes steel three times more resistant to corrosion and increases its ductility, protecting the metal from cracking during mechanical treatment.

During the tests, samples of ZAM-coated steel will be exposed to high concentrations of sulphur dioxide in the air, aggressive sea salt aerosols, and high air humidity at low temperatures.

Among other applications, the new coating is used in the production of light thin-walled steel structures. The coating enables better corrosion protection for building structures, increasing the steel’s resistance to oxygen and humidity. According to the company’s statement, ZAM-coated steel is used to manufacture pre-painted steel and products made from it have a service life of over 50 years.

The tests are conducted in line with Russian and global standards. The new product is scheduled to be launched in 2022.
