Structure of PPGI Steel

PPGI steel uses galvanized steel as base metal. And then several layers of organic coatings are painted. Generally, it contains base metal, zinc coating, pre-treatment (chemical conversion coating), primer coating, and top/back coating. Below is a picture for your reference.

PPGI Coil Making Process

1. Pre-treatment: Uncoil and weld the steel coils for continuous processing. Through pre-treatment, such as cleaning, degreasing, it will remove the rust and impurities on the surface of steel coil and form a layer of chemical coversion coating out of steel coil. 

2.Coating. Both sides will be coated for the first time, and then be dried. After cooling down, the coils will be painted and dried again.

3.Cooling down the coils below 40 °C. After the quality control system, the steel sheet will be rolled up through outlet looper.
