The full form of PPGI is pre-painted galvanized iron. It is a kind of color coated steel or pre-painted steel, which is an extension of GI. As the name implies, it uses zinc-coated steel as substrate, and then it is cleaned, pre-treated, and applied with layers of coatings to make it more beautiful and durable to use. We adopt the coil coating process to make PPGI coils. With slitting, shearing, and roller equipment, we also have strips, plain and corrugated sheets for sale.
