Users of high corrosion resistance steel will have a wider range of choice when an
addition to the product line made by Nippon Steel goes on the market in October 2021. The new product,
ZEXEED, has twice the resistance in flat areas than conventional high corrosion resistant steel now in
use.
Since 2000, Nippon Steel’s high corrosion resistant coated steel SuperDyma™ and ZAM™
have been adopted by manufacturers in the building materials, automobiles, home appliances, and industrial
machinery industries, and their cumulative global sales have reached approximately 15 million tons. ZEXEED
was developed to satisfy the market demand for higher corrosion resistance. ZEXEED will particularly be an
excellent material of choice to be used for projects in a harsh environment or in coastal or other areas
with high humidity and high temperature.
ZEXEED has superior corrosion resistance that far exceeds both that of post-plating, commonly used in the
civil engineering and social infrastructure sectors, and conventional high corrosion resistant steel.
Tests conducted by Nippon Steel confirmed that ZEXEED’s corrosion resistance of flat areas is about
twice as high as that of the conventional steel of the same kind and about 10 times higher than that of
hot-dip galvanized (GI) steel.
By taking advantage of the excellent corrosion resistance of ZEXEED, we will not only reduce life cycle
costs by extending the service life of our products, but also meet the various needs of our customers and
society, such as the urgent issues of measures to counter aging social infrastructure, as well as process
and labor saving associated with the decrease in the working population.
Nippon Steel will also launch the Nippon Steel High Corrosion Resistant Coated Steel Sheet Series by
adding the newly developed ZEXEED to our existing high corrosion resistant coated products with various
functions that we have developed over our long history. The company has been a leader in the industry
regarding high corrosion resistant coated steel for many years, and has developed a wide variety of
functions to steel and an extensive menu of products that no other company can offer.
Through the provision of ZEXEED and the new Series, Nippon Steel is contributing to the realization of a
safer and more secure society, as well as to the reduction of energy consumption and environmental impact,
and ultimately to the establishment of a recycling-oriented society.
