Description of PPGI & PPGL STEEL
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 refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming.
The hot-dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminum, or alloy coatings of zinc/aluminum, zinc/iron and zinc/aluminum/magnesium which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel.
In our Hometown, Jinghai County, which is a little county in North of China, over 30 million tons of such coated steel is produced today in over 300 coating lines.
