Abstract- Prepainted galvanized (PPG) steel coils, comparing to galvanized coils, have better corrosion resistance and fascinating decorative properties with their color alternatives and glossy appearance. Color of PPG coils, during service period, by the effect of environmental conditions, fades and their surface lose their glossy appearance. This study investigated the color and gloss stability of PPG steel sheet samples, painted with 14 different colors and 3 different paint type. 23 parallel samples were exposed to natural environmental conditions during 2 years at two different locations, Florida/USA and Dörtyol/Hatay/Turkey. For natural tests, environmental meteorological parameters such as temperature, humidity, rain and various weather conditions are recorded monthly. This study shows the effect of natural environment of Dörtyol/Hatay/Turkey location and the regions similar meteorological conditions like Dörtyol/Hatay/Turkey on color and gloss of PPG coils.
