PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.
PPGI steel coils are the products that use hot-dip galvanized sheet, hot-dip aluminum-zinc sheet, electro-galvanized sheet as based sheets, after surface pretreatment (chemical degreasing and chemical conversion treatment), one or more organic paints are coated on the surface, followed by baking and curing.
It is also named after the color steel coil plate coated with various colors of organic paint, referred to as color coated coil. The color-coated steel belt uses a hot-dip galvanized steel belt as the base material.
In addition to the protection of the zinc layer, the organic coating on the zinc layer also plays a role in covering and protecting, preventing the steel belt from rusting. Its service life is longer than that of the galvanized belt for about 1.5 times.
