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.
