Learn about PPGI

In today's rapidly evolving industrial landscape, Prepainted Galvanized Iron (PPGI) has become an important material with a variety of applications. PPGI combines the strength of galvanized iron with the aesthetics of pre-painted iron, resulting in a versatile material that can be used in a variety of fields. PPGI: Production and Ingredients
PPGI is a product that combines two basic ingredients: galvanized iron and pre-painted paint. Galvanized iron, also known as galvanized steel, is steel coated with a layer of zinc to prevent corrosion. This zinc layer not only enhances the material's durability, but also provides an excellent surface for paint to adhere to.

PPGI's pre-coatings are typically composed of a variety of resins, pigments and additives. These coatings are both functional and aesthetically pleasing. Functionally, they provide an extra layer of protection against corrosion, UV radiation and environmental factors. Aesthetically, these coatings enable manufacturers to offer a variety of colors and finishes to suit different design preferences. Production Process

The production of PPGI involves multiple steps that transform galvanized iron into a vibrant, durable material suitable for a variety of applications.

Surface Preparation: Galvanized iron coils are thoroughly cleaned and surface treated to ensure proper adhesion of the pre-applied coating.

Primer: A primer coat is applied to improve the bond between the galvanized surface and subsequent layers of paint.

Paint Application: Apply multiple coats of paint to achieve desired color and finish. These paint layers are carefully formulated to provide protection against corrosion and other external factors.

Curing: The coated web is then cured at a controlled temperature to ensure proper adhesion of the paint layer and optimal performance.

Cooling and Inspection: After curing, the rolls are cooled and undergo strict quality inspection before being cut into sheets or rolls of various sizes for distribution and further processing.
