ppgi is prepainted galvanised steel, also known as precoated steel, coil coated steel, color coated steel etc.
a galvanised steel sheet in coil form is cleaned, pretreated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates.these coatings are applied in a continuous process known as coil coating.
the steel thus produced in this process is a prepainted, prefinished ready to use material. ppgi is the material which uses galvanised steel as the basic substrate metal. there could be other substrates such as aluminum, galvalume, stainless steel, etc.
