1, Color Coated Steel Roll Brief Introduction
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, that is the galvanized steel
is painted before forming,as opposed to post painting which occurs after forming

4. Color Coated Steel Roll Production Line
It is a continuous, automated process for coating metal before fabrication into end products.
The steel or aluminum substrate is delivered in coil form from the rolling mills. Color steel coil
is positioned at the beginning of the coating line, and in one continuous process, the coil is
unwound, pre-cleaned, pre-treated, pre-primed, and prepainted before being recoiled on the
other end and packaged for shipment
