PPGI sheet is short for pre-painted galvanized steel sheet. It is a kind of pre-painted steel sheet, which uses galvanized steel sheet as the base metal. Then it is painted with one or several layers of organic coatings after surface pretreatment (degreasing and cleaning), and then baked and solidified continuously. Then the coils will be cut into sheets of the desired size. Through rolling equipment, the plain sheets can be profiled into corrugated PPGI sheets.
