Contributing to building a society with reduced environmental burden
NS ZINKOTE® color steel has realized ultimate thinness and high formability to unprecedented levels compared to conventional coated steel sheet. Color top coating performed by an electrogalvanized process frees customers from the need for the coating process, the procurement of fuel, and the treatment of waste liquid while eliminating concern about emission gas.
SuperDyma®, a high corrosion-resistant alloy hot dip galvanizing steel sheet, is coated with a zinc alloy containing around 11% aluminum, around 3% magnesium, and a tiny amount of silicon. SuperDyma® has four times the corrosion resistance of general grade galvanizing steel. Thus, the amount used for coating to achieve similar corrosion-resistance performance can be reduced by a quarter. In addition, the coating process can be reduced, resulting in the saving of coating materials, in other words, petroleum resources.
Our lightweight welded H-beams are lighter and less thick than conventional rolled H-beams and highly regarded for their durability and high dimensional precision. They are used in pre-fabricated houses as well as in beams of wooden houses.
Shafts used in paper feeders and other parts of printers contain lead to make it easy to process the shaft. Nippon Steel’s EZ and Sumi-Green CS are made of lead-free steel but ensure similar free-cutting performance and superior coating performance compared to conventional steel that contains lead.
Low-alloy corrosion-resistant steel ARUTEN hinders the occurrence of red rust due to a general coating that contains zinc in outside high-salt environments. It hinders the occurrence of red rust even without a coating in indoor lower-salt environments. This steel has signifi cantly reduced the amount of additives used, such as nickel, chrome, and molybdenum, compared to stainless steel. It is thus economical and eco-friendly.
Nippon Steel’s SBHS500 was adopted in the Tokyo Gate Bridge, which was constructed to ensure smoother transportation and relieve traffi c jams. This new steel is extremely strong and has reduced the overall weight of steel materials used by 3%. This has also resulted in a signifi cant reduction in CO2 emissions for the whole process from the manufacturing of steel materials and the construction of bridges to transportation. In addition, compared to conventional bolted connections, the adoption of an all-welded structure resulted in a less tongued-and-grooved face, leading to a reduction in the repainting burden.
Reduced power consumption in homes
Use of the NS Super Frame Method™ of construction enables steel-framed houses to realize enhanced fire-resistant, noise- and heat-insulating, and more highly durable characteristics.
TV display units require a heat sink on their back. We developed the steel sheet that releases heat near to the theoretical limit. It is thinner and emits significantly less CO2 than an aluminum sheet. This has been adopted by Panasonic Corporation for ultra thin TV displays.
