Steel sheets have found wide-ranging applications that support various industries and the daily lives of people everywhere. These applications include automobiles, home appliances, construction materials, housing materials, beverage cans, and transformers, to name but a few. In line with worldwide economic growth, particularly in emerging nations, demand for steel sheets is steadily expanding. Nippon Steel & Sumitomo Metal is a very competitive supplier of steel sheets due to its ability to combine an extensive product lineup with a quick response to customer requirements of all kinds. The development and introduction of highly functional steel materials by applying leading-edge technology meets society's increasingly sophisticated needs for environmental protection and energy saving.


The use of zinc, as well as aluminum, magnesium, and silicon, in the coating of hot-dipped Zn-Al-Mg-Si alloy coated steel sheet provides extremely high corrosion resistance.

It is used in a wide range of applications, primarily as structural steel.

Various products in the NS ZINKOTE series (and typical characteristics)

About the coatings Required characteristics Product
Organic coatings
  • The effect of the surface coating is to realize high formability and lubricity.
  • Tends to repel water well.
Focusing on conductivity: QS1 (good conductivity, smudge-proof) is a standard thin film with well-balanced conductivity and corrosion resistance.
Focusing on corrosion resistance/scratch resistance QF1 (highly corrosion resistant, smudge-proof) is a specialty thick-film coating with very high corrosion resistance.
Focusing on corrosion resistance/scratch resistance QFK (slick, smudge-proof) is highly corrosion resistant and slick
Inorganic coatings
  • Excellent conductivity and adhesion in a thin film.
  • Can also be made compatible with water-based paints.
  • Tends not to be water repellent.
Focusing on conductivity, coating performance and ironing performance QM (high-performance (inorganic)) thin film is highly conductive, and has sufficient corrosion resistance.
