PPGI is GI steel sheets coated with a colored paint layer.
Characteristics: PPGI steel sheets offer not only the corrosion resistance of galvanized steel but also a vibrant and customizable appearance. They are widely used in construction, manufacturing, and decorative applications.
Uses: Roofing, wall panels, door frames, appliance housings, etc.
The full form of PPGI is pre-painted galvanized iron. It is a kind of color coated steel or pre-painted steel, which is an extension of GI. As the name implies, it uses zinc-coated steel as substrate, and then it is cleaned, pre-treated, and applied with layers of coatings to make it more beautiful and durable to use. We adopt the coil coating process to make PPGI coils. With slitting, shearing, and roller equipment, we also have strips, plain and corrugated sheets for sale.
Product Parameters
Color Selection
We provide many colors to choose from, the following are common colors, if you like other colors or patterns, please send us the RAL color code.

Advantages of Color Coated Plate
Custom Colors
You can choose any RAL color, as well as customize the pattern according to your needs. The beautiful surface makes the color coated board decorative. So it can be directly used in many fields.
Tough Soating
Color coated steel plate including PPGL plate PPGI steel, the use of continuous coil coating, the surface luster bright, no cracking, no peeling. In addition, it can keep the color for at least 10 years.
Excellent Mechanical Properties
The color coated plate retains the mechanical properties of the base metal, such as tensile strength. In addition, the application of the coating can protect the surface from rust, thereby extending its service life. Studies have shown that the service life of color-coated steel sheets is 50% longer than that of galvanized steel sheets.
Easy to Use
Different from the coil, the color coated plate is a kind of finished product. This means that it can be directly used in many industries. Considering its light weight, it is easy to carry and install. In addition, due to its aesthetic appearance, no additional decoration is required. Also, less maintenance is required during the service life.
Coating Type
In the coil coating, the durability of the role is the resin and pigment, the most commonly used finish polyester, silicon modified polyester, high durability polyester and polyvinylidene fluoride.
Polyester PE
Good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, low cost.
Silicon Modified Polyester SMP
The hardness, abrasion resistance and heat resistance of the coating film are good; as well as good external durability and powder resistance, gloss retention, general flexibility and medium cost.
High Durability Polyester HDP
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride PVDF
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited color, and high cost.
