PPGI steel is short for pre-painted galvanized iron, which refers to pre-painted zinc-coated steel. As the name implies, PPGI commonly uses a hot-dip zinc-coated steel (GI) as a substrate. Then the GI sheet in coil form is cleaned, pre-treated, and painted with layers of organic coatings, such as PE, SMP, HDP, PVDF, etc. The painting process is continuous, which is known as coil coating process. That’s why PPGI steel consists of several layers, namely base metal, zinc coating, pre-treatment (chemical conversion coating), primer coating, and top/back coating.

PPGL steel is a durable, colorful, and economical building material. It is the abbreviation for pre-painted galvalume steel, which is with Al-Zn coated steel sheet substrate. Then the Al-Zn coated steel is painted continuously in coil form. Because of its excellent heat and corrosion resistance, it has become the preferred material for a wide range of construction uses, particularly roofing and walling. Baiyong Steel has exported its products to many countries all over the world, such as Nigeria, Kenya, Turkey, Spain, Poland, etc. Please contact us for details!
