PPGI
Product Introduction of PPGI
PPGI is pre-painted galvanized steel, also known as pre-coated steel, color coated steel, etc. Using Hot Dip Galvanized Steel Coil as the substrate, PPGI is made by first going through surface pretreatment, then coating one or more layers of liquid coating by roll coating, and finally baking and cooling. The coatings used include polyester, silicon-modified polyester, high durability, corrosion resistance, and formability.
We are a PPGI & PPGL manufacturer in China. Our PPGI (Prepainted Galvanized Steel) & PPGL (Prepainted Galvalume Steel) are available in a variety of specifications. We could also provide the product life length lasts for decades as customers required.

PPGI Product Details
Color-coated Roll Coating Type :
Polyester (PE),Good bacteria, little color, wide range in formability and outdoor, medium chemical resistance, low cost.Silicon modified polyester
Namely (SMP), the coating film has good abrasion resistance and heat resistance, good external appeal and anti-spongification, maintenance and retention, weak and moderate, and the cost is medium.High acceptance polyester.
Namely (HDP), excellent color retention and impact resistance, excellent outdoor reflection and resistance, good paint film resistance, obvious color, and appearance.Polyvinylidene fluoride
Namely(PVDF),appearance color and resistance, appearance, appearance appearance and chalking resistance, excellent solvent resistance, good styling, resistance, limited color, and high cost.
Coating Structure Type:
Apply twice on the upper surface, once on the lower surface, and bake twice.
The upper and lower surfaces are coated twice and baked once.
The upper and lower surfaces shall be coated twice and baked twice.
Use of different coating structures:
The single-layer back paint has poor corrosion resistance and scratch resistance, but it has good adhesion. mainly used in sandwich panels.
The back paint has good corrosion resistance, scratch resistance and processing formability, and has good adhesion.Applicable to single-layer profiled plate and sandwich plate.
The double-layer back paint has good corrosion resistance, scratch resistance and processing formability. Most of them are used for single layer Laminated plate, but its adhesion is poor, so it is not suitable for sandwich plate.
Color coated substrate classification:
Hot dip galvanized substrate
The product obtained by coating organic coating on hot-dip galvanized steel plate is hot-dip galvanized color coated plate. In addition to the protection of zinc, the organic coating on the surface of hot-dip galvanized color coated plate also plays the role of isolation protection and rust prevention, and its service life is longer than that of hot-dip galvanized plate. The zinc content of hot-dip galvanized substrate is generally 180g / m2 (double-sided), and the maximum zinc content of hot-dip galvanized substrate for external use is 275g / m2.
Hot dip aluminum zinc substrate
The hot-dip aluminum zinc steel plate (55% Al Zn) is used as the newly coated substrate, and the aluminum zinc content is usually 150g / ㎡ (double-sided) The corrosion resistance of hot-dip aluminum zinc plate is 2-5 times that of hot-dip galvanized plate. It will not be seriously oxidized or scale when used continuously or intermittently at temperatures up to 490 ℃. The ability to reflect heat and light is twice that of hot-dip galvanized steel plate, and the reflectivity is greater than 0.75. It is an ideal building material to save energy.
Electro galvanized substrate
The product obtained by baking with electro galvanized sheet as the substrate and coated with organic coating is electro galvanized color coated sheet. Because the zinc layer of electro galvanized sheet is thin and the zinc content is usually 20 / 20g / m2, this product is not suitable for making walls and roofs outdoors. However, due to its beautiful appearance and excellent processing performance, it can be mainly used for household appliances, audio, steel furniture, indoor decoration, etc.
PPGI advantage:
- good durability, corrosion resistance and longer life compared to galvanized steel;
- good heat resistance, and galvanized steel sheet compared to the more difficult to change color at high temperature;
- It has good thermal reflectivity
- it has similar machinability and spraying performance to galvanized steel sheet
- It has good welding performance.
With good performance to price ratio, durable performance and very competitive price. As a result, both architects, engineers and manufacturers have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
What are the characteristics of the color coated coil substrate:
Electro-galvanized substrate: The coating is thinner, and the corrosion resistance is not as good as the hot-dip galvanized substrate;
Hot-dip galvanized substrate: the thin steel plate is immersed in a molten zinc tank to adhere a layer of zinc to the surface. This galvanized sheet has good paint adhesion and weldability.
Hot-dip aluminum-zinc substrate:
The product is plated with 55% AL-Zn and has excellent corrosion resistance. Its service life is more than four times that of ordinary galvanized steel sheets. It is a replacement product of galvanized sheet.
