Manufacturer 0.12-4.0mm PPGI PPGL Color Coated Sheet Plate
Prepainted Galvanized Steel Coil
PPGI Steel Coil Introduction
Galvanized steel is to prevent the steel plate surface from
corrosion to extend its service life, in the steel plate surface
coated with a layer of metal zinc, the zinc coated steel plate are
called galvanized sheet.
According to the production and processing methods can be divided
into the
1) hot dip galvanized steel. Thin plate in melting zinc bath, make
its surface adhesion of a layer of zinc sheet. At present mainly
adopts continuous galvanizing process, namely the continuous roll
of steel plate in the melt zinc plating tank made of galvanized
steel sheet;
(2) the alloying of galvanized steel. This kind of steel plate is
made by hot dip method, but after the slot, immediately heated to a
temperature of about 500 ℃, it make the generation of zinc and iron
alloy membrane. This kind of galvanized sheet with good coating of
sex and weldability;
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.
