Galvanised Iron can be pre coated though various painting gives us PPGI over wide ranges of colors and different RAL. And with sustrated layers as Zinc/Aluminium known as Galvalume its known as PPGL

Pre Painted Galvanized Coils & how it is produced
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.
The term is an extension of GI which is a traditional abbreviation for Galvanized Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. 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 aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/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.
PPGL may be used for pre-painted 55%Al/Zn alloy-coated steel (pre-painted GALVALUME steel)
