HOT DIP GALVANIZEDSTEEL SHEETHOT DIP GALVANIZED STEEL SHEET
"JFE is sensitive to the earth and human beings"This is our motto.Our galvanized steel sheet productshave been developed to meet the strictrequirements of demanding customers.Our goal is to help people and contributeto society by manufacturing these andother products which provide highquality and performance.JFE Galvanized Products are fluttering to the Future
The applications of steel sheets in daily life are constantly expanding.Coated steel products such as JFE's galvanized steel sheets have enjoyedparticularly strong growth in fields where corrosion resistance and costreduction by process omission are important. Our coated steel sheets offersuperior economy in construction and automotive applications, electricappliances, and electronic equipment.JFE Steel Corporation, who holds ISO 9001, QS-9000 and ISO 14001certifications, has made an effort for development and production ofvarious kinds of hot dip galvanized products thanks to most modernfacilities and long time accumulated technologies.JFE's wide range of hot dip galvanized products include pure zinc coated,alloy coated, and unique high corrosion resistance chemically treated steelsheets which respond to the increasingly advanced and diverse needs ofchanging markets. As the results, JFE has got sincere reliance from thedomestic and overseas customers.Understanding the excellent characteristics of JFE products aiming futureprogress, sincere patronage from the customers are welcomed.HOT DIP GALVANIZED STEEL SHEET ContentsGalvanized steel sheet products and Characteristics 2Hot dip galvanized steel sheet products and Characteristics 3Manufacturing process 4Chemical treatment of hot dip galvanized products 6JFE GALVAZINCTM 7JFE GALVAZINC ALLOYTM 17GALVALUME STEEL SHEET 27ECOGAL-NeoTM 30Eco FrontierTM Series 33Packaging and labeling/Description of steel grade/Instructions for ordering 36Handling precautions 37“JFE GALVAZINC”, “JFE GALVAZINC ALLOY”, “ECOGAL-Neo”, and“Eco Frontier” are registered trademarks of JFE Steel Corporation in Japan.
HOT DIP GALVANIZED STEEL SHEETGalvanized steel sheet products and eristics Zinc coated by hot dip galvanizing. Light coated products have good weldability andformability. Usable from general processing to deepPure ZincJFE GALVAZINCdrawing according to application. Heav y coated products have superior corrosionresistance. Wide application are possible by selectingspangle or a post treatment. Zn-Fe alloy coated by hot dip galvanizing and annealing.JFE GALVAZINC ALLOY Zn-Fe coating has superior paint adhesion and corrosionresistance. Weldability is superior to JFE GALVAZINC products.Galvanized steel sheet products and Characteristics ECOGAL-Neo is a Zn-5%Al-based alloy-coated steelsheet, which realized higher corrosion resistance thanHot dipgalvanizingconventional Zn-5%Al alloy-coated steel sheets byadding small amounts of magnesium (Mg) and nickel (Ni)to the Zn-5%Al alloy-coating. A high corrosion resistanceAlloyECOGAL-Neochromate-free conversion coating is also applied. In addition to excellent corrosion resistance, the coatedlayer has good adhesion and ductility, securing excellentformability. Beautiful external appearance enables use in applicationswithout painting. Alloyed coating cont aining zinc and about 55 %aluminum.GALVALUME STEEL SHEET Products have heat resistance and heat reflectionproperty of aluminum in addition to corrosion resistanceof zinc and aluminum.
