PPGI Prepainted Galvanized Steel Coil is a composite metal material,which is a plate made by surface treatment and coating with organic coating on the basis of galvanized steel sheet or electro-galvanized steel sheet. Compared with traditional spraying and electroplating, PPGI steel coil has lower maintenance cost and longer service life.
The purpose of color coating is to enhance aesthetics; It offers a variety of colors and surface effects-such as matte or high-gloss-to meet diverse needs,gives steel a more appealing look for applications like building facades and household appliance exteriors. In addition, color coating can also enhance the corrosion resistance of steel, especially for some environments with the risk of chemical exposure. Color coating can serve as the first line of defense to prevent corrosive media from contacting the galvanized layer and the steel substrate.
PPGI is pre-painted galvanized steel, with good mechanical strength, formability, good decorative and corrosion resistance.The coating is wear-resistant, UV-resistant, and not easy to fade or peel off,can maintain long-term beauty and stability in harsh environments.

The coating is wear-resistant, UV-resistant, and not easy to fade or peel, allowing colour gi sheet to maintain long-term beauty and stability in harsh environments,and can be directly processed, it provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc., and has played a good effect of replacing wood with steel, efficient construction, energy saving, and pollution prevention.
PPGI is a type of plate material obtained on a continuous unit using cold-rolled strip steel, galvanized strip steel (electroplated and hot-dip galvanized) as substrates, surface pre-treatment (degreasing, cleaning, and chemical treatment), roller coating method, one or more layers of liquid coating, and baking and cooling.
