PROBLEM TO BE SOLVED: To provide a plating method for forming a plating film with uniform thickness and excellent appearance. SOLUTION: The hot-dip galvanizing method includes a step of treating an iron-based body to be plated with a ferric chloride solution, as pretreatment for plating. The hot-dip galvanizing method may include treating the iron-based body to be plated with a flux after having treated the iron-based body with a ferric chloride solution, and then hot-dip galvanizing it. The above plating method may also include pickling the iron-based body to be plated which has been treated with the ferric chloride solution, before treating it with the flux. The hot-dip galvanizing method may also include shot-blasting the iron-based body to be plated, and then treating it with the ferric chloride solution. The above method may also include rolling, machining or shot-blasting an iron-based body to be plated and then treating it with the ferric chloride solution. The iron-based body to be plated may be a screw or a spring. The hot-dip galvanizing method may be a hot-dip zinc plating method, a hot-dip zinc-aluminum alloy plating method, or a hot-dip zinc-tin alloy plating method. COPYRIGHT: (C)2008,JPO&INPIT
