Applications of PPGI Coil

Pre-painted galvanized steel coil can be further processed into plain, profile, and corrugated sheets, which can be used in many areas, for example,

1. Construction industry, such as roofing, interior, and exterior wall panels, the surface sheet of the balcony, ceiling, partitioning walls, windows, door panels, etc. The PPGI steel is durable and wear-resistant and it will not be deformed easily. So it is also widely used in the renovation of buildings.

2. Transportation, for example, decorative panels of the car, deck of train or ship, containers, etc.

3. Electrical equipment, mainly used to make shells of the freezer, washing machine, air conditioner, etc. The PPGI coils for home appliances are of the best quality, and the production requirements are the highest.

4. Furniture, like wardrobe, locker, radiator, lampshade, table, bed, bookcase, shelf, etc.

5. Other industries, such as roller shutters, advertising boards, traffic signboards, elevators, whiteboards, etc.

Review on Pre-painted Galvanized Steel Coil

What Is PPGI Coil?

PPGI coil is short for pre-painted galvanized steel coil. It is a kind of color-coated steel, that uses hot-dip galvanized steel or electro-galvanized steel (zinc coating) as substrate and is coated with several layers of organic coatings to protect it from rusting. Except for the PPGI steel coil, Wanzhi Steel also has a color-coated coil using galvalume steel (PPGL) and hot or cold rolled steel as the base metal.

Hot-dip Galvanized PPGI Steel

At Wanzhi Steel, we mainly use hot-dip galvanized steel sheets as the base metal. With the protection of the zinc layer and organic coating, its service life is longer than that of the hot-dip galvanized sheet. The maximum zinc layer available is 275 g/㎡.

Electro-galvanized PPGI Steel

The electro-galvanized sheet is used as the substrate. Because the zinc layer of the electro-galvanized sheet is thin, usually 20 g/㎡, its corrosion resistance is not as good as the hot-dipped galvanized sheet. So this product is not suitable for making walls and roofs for outdoor uses. But it has a beautiful appearance and excellent processing performance, it is mainly used in home appliances, steel furniture, interior decoration, etc.

PPGI Coil Manufacturing Process

Wanzhi Steel adopts the coil coating process, which refers to the galvanized steel being cleaned, pre-treated, and painted in coil form continuously. Let’s review the PPGI coil manufacturing process step by step. You can also follow our YouTube channel for more videos.

PPGI Manufacturing Process

PPGI Coil Manufacturing Process

1. Zinc-coated steel substrate is uncoiled and welded and then goes through the inlet looper to be cleaned and pretreated continuously.

2. After pre-treatment, a layer of chemical conversion coating is formed on the surface.

3. Coil coating process. The coil coating process is one of the most widely used color coating processes. Generally, we will paint and dry the back and top sides of the base metal twice (namely twice-side twice-coating method). For some special uses, it may be painted and dried three times or once.

4. Cool down the coated steel.

5. After quality testing, the color coating sheet will be rolled into coils for sale.

That’s why there are several layers of pre-painted galvanized steel coils, including, base metal, zinc coating (two sides), chemical conversion coating (two sides), primer coating (two sides), and top/back coatings.

Surface Treatment

1. Film Laminating

This process involves applying a layer of transparent organic film (30-50 ㎛)to the steel coil at a high temperature. It offers some unique properties, such as fire resistance, fingerprint resistance, excellent durability, anti-fouling ability, etc. This treatment method can protect the steel coil well during storage and transportation. Of course, it will be more expensive. But if you use the PPGI coil as front panels of refrigerators, high-end cabinet panels, the shell of the set-top box, etc., film laminating will be a good choice to prevent scratching. Below is a video for your reference.

2. Embossing

Embossed PPGI steel coil is designed with different patterns. The most popular patterns are stucco, diamond, etc. And it is customizable. Compared to the smooth steel coil, it has a vivid 3D effect.

How to Decide Coatings for PPGI Coil?

There are many PPGI coils with different paints, colors, and coating thicknesses. You can choose according to your requirements, for example, the use environment, design life, etc.

1. Coating Types

When choosing a primer, you need to consider the adhesion of the primer; while for top coating, corrosion resistance, and color retention will be more important.

There are four commonly used paints, including polyester (PE), silicone-modified polyester (SMP), high-durability polyester (HDP), and polyvinylidene fluoride (PVDF). PE coating is of good adhesion and it is widely used as a primer. While HDP and PVDF will be more suitable as a top coating because of their excellent durability and color retention.



2. Thickness of Coating

At Wanzhi Steel, the painting thickness is usually 5/10 ㎛. The max top paint can be 35 ㎛. Generally, the thicker the coating, the better the durability. You can choose according to the use environment. For example, a single layer of back coating is recommended for sandwich wall panels. If you have special requirements, please let us know.

3. Coating Colors

What color is the best? It mainly depends on the use environment, your preference, and market demand. For example, beauty is the first concern for civil buildings. But the corrosion resistance is more important for industrial buildings. Besides, the light color paint has a stronger heat reflection ability. Moreover, the color change in dark colors is more obvious than that in light colors.

More than that, you can also appoint the paint brands, such as AkzoNobel, Nippon, etc. Welcome to contact us for details!

Q: As mentioned, PPGI uses galvanized steel as the base metal. But why PPGI coil price is similar to and even lower than the galvanized steel coil price?

A: The galvanized steel coil price mainly depends on the zinc coating thickness. The thicker the zinc layer, the higher the cost and the better the corrosion resistance. The galvanized steel used in PPGI has a thinner zinc coating. Also, the PPGI coil price will be different from the painting you choose, as well as the paint thickness. For example, the painted steel whiteboard price will be much higher than that of common PPGI steel. If you have special requirements, please let us know. We will offer custom solutions and a price list for you.
