PPGI Steel Coil Introduction
PPGI is pre-painted galvanized iron, also known as pre-coated steel, zinc coated steel, color coated
steel etc., typically with a hot dip zinc coated steel substrate. PPGI is an industrial steel product with multiple uses. It is a
form of galvanized iron that is also dipped into zinc. However, the
zinc coat is pre-painted in the factory instead of wait until after
the steel is formed. Applying a zinc coat prevents rusting. PPGI is
also known as metallic coated steels, or pre-coated steel. This
product will typically come in the form of a coil. This steel is
often not costly and can last for a long period of time.
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. Similarly, PPGI may
sometimes be used as a general term for a range of metallic coated
steels that have been pre-painted, but more often refers more
precisely to pre-painted zinc coated steel.
Zinc coated steel substrate for PPGI is typically produced on a
continuous galvanizing line (CGL). The CGL may include a painting
section after the hot dip galvanising section, or more commonly the
metallic coated substrate in coil form is processed on a separate
continuous paint line (CPL). Metallic coated steel is cleaned,
pre-treated, applied with various layers of organic coatings which
can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often
referred to as Coil Coating.
