ELECTROGALVANIZED STEEL SHEET

JFE Galvanized Products

"JFE is sensitive to the earth and human beings"This is our motto. Our galvanized steel sheet products have been developed to meet the strict requirements of demanding customers.

are fluttering to the Future

Our goal is to help people and contribute to society by manufacturing these and other products which provide high quality and performance.

The applications of steel sheet in daily life are constantly expanding. Coated steel products such as JFEs galvanized steel sheets have enjoyed particularly strong growth in elds where corrosion resistance and cost reduction by process omission are important. Our coated steel sheet offer superior economy in construction and automotive equipment. applications, electric appliances, and electronic

In addition to attractive appearance and excellent corrosion resistance, JFEs electrogalvanized products are available with an extensive range of chemical treatments, responding to the increasingly advanced and diverse needs of changing markets.

JFE Steel Corporation, who holds ISO 9001, QS-9000 and ISO 14001 certications, is also a leader in environmental protection. As part of our line of galvanized products, we recently developed the chromatefree Eco Frontier Series, which has already earned an outstanding reputation with users in and outside of Japan.

Galvanized products and characteristics2

Pure zinc Electrogalvanizing

JFE EXCELZINC

Smooth, attractive surface produced by electro-plating. Formability of coating is excellent, with same mechanical properties as base metal. Weldability is also good due to light coating. Paintability, anti-fingerprint property and lubricity can be added by post-treatment. Surface coated by zinc-nickel alloy. 3 to 5 times corrosion resistance than that of pure zinc coating. Superior formability and weldability. Zinc coated by hot dip galvanizing. Light coated products have good weldability and formability. Usable from general processing to deep drawing according to application. Heavy coated products have superior corrosion resistance. Wide application are possible by selecting spangle or a post treatment. Zn-Fe alloy coated by hot dip galvanizing and annealing. Zn-Fe coating has superior paint adhesion and corrosion resistance. Weldability is superior to JFE GALVAZINC products. Coated layer consists of mainly zinc and 5% aluminum with small amount of mish metal (rare earth elements). Adhesion and ductility of coated layer is good, and it shows excellent formability. Used for painted sheets due to good paintability. Alloyed coating containing zinc and about 55 % aluminum. Products have heat resistance and heat reflection property of aluminum in addition to corrosion resistance of zinc and aluminum. Surface is attractive white silver.

Characteristics There is no mechanical properties change with coating and so superior formability of the base metal is attained. Same weldability as that of hot rolled and cold rolled base metal if spot and seam welding conditions are properly selected. Finished surface after painting is good because of smooth surface. With phosphate treatment, paint adhesion is excellent without pretreatment for painting. Oxidation of zinc is inhibited by chemical treatment or oiling, so it has good corrosion resistance. Even if base metal is exposed by scratches during working, red rust is delayed. Coated layer has hard surface and low friction coefficient and so it has good formability as that of base metal. Melting point of the alloy coat is high, so welding is easy. Finished surface after painting is good because of smooth surface. It has less occurrence of paint swelling or peering and has good paint adhesion. It has moderate sacrificed corrosion resistance by coated layers and has stable corroded generatives and it has 3-5 times corrosion resistance compared with normal electrogalvanized products.

Packaging and labelingPackagingElectrogalvanized products are packed according to applicable standards and preserved in a properly controlled environment until shipment.

LabelingLabels showing the product standard, dimensions, mass and product serial No. are attached to the electrogalvanized product.

Handling precautionsIn using electrogalvanized steel sheets, the following precautions should be taken in order to ensure optimum use:Storage (1) When receiving products, check for moisture in the package. Dry immediately if wet. (2) Use adequate care to prevent moisture in spaces between sheets, coiled strips, and work pieces. (3) Storage areas should be as dry as possible. Storage in damp conditions and/or with broken packaging can result in discoloration or rusting. (4) Repair broken packaging if long-term storage is required. Abrasion marks (black dents) may occur due to pressure if transportation or storage conditions are improper. Handling (1) Steel sheet products have sharp edges. Handle carefully using gloves to avoid injury. (2) Scratches and oil stain due to improper handling can result in paint defects. (3) Lubricated products have a low friction coefficient and slide easily. Coils may collapse (telescope, etc.) due to repeated uncoiling and recoiling. Cut sheets in piles may slide due to impact. Use care in handling and work around storage areas. Processing (1) Some types of lubricating oil erode zinc. Prior testing shall be recommended. Welding (1) For high temperature brazing, nickel-brass brazing material is recommended. Degreasing (1) Insufficient degreasing can cause paint defects. (2) Degreasing by spraying or dipping in a neutral or low alkaline agent is recommended. Strong alkaline agents can damage the strip surface. (3) Adequate rinsing after degreasing is recommended. If degreasing is inadequate, water repulsion can be observed on the strip after dipping in clean water. Use a degreasing method which maintains smooth and uniform water film. Painting (1) Dirt or other foreign matter on the surface will cause paint defects. Degrease/clean adequately before painting. (2) JFE coated steel products are chemically treated to improve paint adhesion. However, certain paints may have poor adhesion with certain zinc coatings. Prior testing is recommended. Undercoating with a wash primer will help ensure good results.Handling precautions33
