Abstract: A steel sheet may be used for hot-dip galvanizing capable of manufacturing hot-dip galvannealed steel sheet(s) with a high Si content and in which alloying unevenness is suppressed. Such a steel sheet for hot-dip galvanizing may include an internal oxide layer containing an oxide of Si between a surface layer of the steel sheet and a steel sheet base portion. The Si content in a chemical composition of the steel sheet may be 1.0 mass % or more. A solid solution Si amount from a surface of the steel sheet to a depth of 1 ?m measured at all four positions including positions of 10 mm, 30 mm, and 50 mm from an edge in a coil width direction and a position of a center in the coil width direction at a rear end in a rolling direction of the steel sheet for hot-dip galvanizing may be 1.4 wt. % or less.

Abstract: A method for manufacturing a hot-dip galvanized steel sheet having a high Si content and good plating adhesion. The method for manufacturing a hot-dip galvanized steel sheet includes the following: hot-rolling a steel raw material having a Si content of 1.0 mass % or more and coiling a steel sheet at 500° C. to 700° C.; subjecting a surface of the steel sheet after the coiling to an oxidation treatment at a heating temperature of a steel sheet temperature of 750° C. or lower, and subsequently subjecting the surface to a reduction treatment; and subjecting the steel sheet after the reduction treatment to a hot-dip galvanizing treatment to form a Zn-plated layer on a surface of the steel sheet.

Abstract: Provided are a Zn—Mg electroplated metal sheet excellent in corrosion resistance, formability and productivity, and a fabrication process therefor. The Zn—Mg electroplated metal sheet comprises a Zn—Mg electroplated layer including Mg and Zn, the Zn being a main component, formed on at least one surface of a metal substrate material. The Zn—Mg electroplated layer shows more excellent corrosion resistance by including a C component therein. The Zn—Mg electroplated metal sheet can be fabricated by performing electroplating with an acidic aqueous solution including metal salts of Zn and Mg, and in addition, a surface active agent.

Abstract: Disclosed herein is a metal sheet with anticorrosive coating which exhibits outstanding corrosion resistance, pitting corrosion resistance, and red rust resistance. It has the anticorrosive coating on at least one side thereof. The anticorrosive coating is formed from an anticorrosive paint which contains a metallic zinc powder and at least one kind of metal salt rust inhibitor. The metal salt is a salt of a metal which is more base than zinc. The metal sheet may be a steel sheet. The metal salt rust inhibitor may be a phosphate or a phosphomolybdate.
