Corrosion performance of hot-dip galvanizing steel sheet applied on the oil tank roof was investigated by the laboratorical corrosion simulation test and the exposure test. The corrosion environment of inner side of oil roof was assumed to be dry and wet condition which pH indicate about 5 containing sulfuric acid by examination of corrosion products. Galvanizing steel sheet showed excellent corrosion resistance in the accelated test-water spray test containing sulfuric acid and the exposure test in the real oil roof. Welding condition of these galvanizing steel sheet was also important factor in the corrosion resistanse. Galvanic protection action of Zn was also effective in the heat affecting zone by welding.From these results, the life cycle of oil tank will be prolonged by application of Galvanizing steel sheet.
