Nippon Steel Corporation is pleased to announce that they have begun offering a 30-year service life warranty program for ZEXEED™, the company’s high corrosion resistant coated steel (such warranty program, the “Warranty Program”), in relation to perforation caused by corrosion in products that satisfy certain requirements.
ZEXEED™, released in October 2021, is a coated steel sheet with superior corrosion resistance that far exceeds that of post-plating, which is commonly used in the civil engineering and social infrastructure sectors. It also exceeds that of Nippon Steel’s conventional high corrosion resistant coated steel sheets and hot-dip galvanized steel. Tests conducted by Nippon Steel, using flat portions and the same plating amount, confirmed that ZEXEED’s corrosion resistance is about twice as high as that of conventional high corrosion resistance steel and about 10 times higher than that of hot-dip galvanized steel.
Nippon Steel is currently receiving many inquiries about ZEXEED™ from customers interested in using it for their international photovoltaic projects. In order to achieve carbon offsetting by 2050, many countries are accelerating their transitions to renewable energies, rapidly increasing the number of photovoltaic projects in particular. However, available areas with suitable mild natural environments for solar panel installation are becoming rare, and as a result such installations are being made increasingly in harsher corrosive environments, such as coastal areas. Due to this, there is a growing need for high corrosion resistant coated steel sheets with a guaranteed service lifespan that is equivalent to the lifespan of solar panels (approx. 25 years) as a material for solar panel mounts to be installed in harsh corrosive environments in photovoltaic projects.
In response to this growing need, Nippon Steel will launch the Warranty Program in June 2022 for products with coating adhesion of 300 g/m2 on both sides, based on the company’s conclusion that it is able to offer such a warranty for ZEXEED™, even if it is used in harsh environments classified as C5 under the corrosivity classification system of ISO 9223, as long as certain requirements are met.
Nippon Steel will continuously work to extend service life of infrastructure and promote renewable energies in harsh environments by delivering ZEXEED™ to a wide range of customers.
