Abstract Zinc is the closest nonferrous metal with steel, to study the volume of zinc resources in scrap, galvanized steel sheet, which takes the largest output in galvanized steel products, is taken for example to study the substance path with steel. A mathematical model of galvanized steel sheet end-of-life recycling and volume of zinc with it was established, according to the corrosion law of galvanized steel sheet using in different environments. Recycling resource volume from scrap galvanized steel sheet was computed under different service life in China. The results show that the life of waste recycling has the maximum impact on zinc resources in Chinese scrap galvanized steel sheet. The longer it scarps recycling, the less current zinc resource volume. The most cumulative volume of zinc resource from scrap galvanized steel sheet can reach 800 thousand tons to 2010 in China.
