Types of Color Coated Steel Coil

According to the base metal, there are different types of pre-painted steel coils.

1. Cold Rolled Steel Color Coil

It is with cold rolled steel as the base metal. This kind of color coated steel is made of non-coated material. It is easy to rust when the air and water go through the organic coating, and it is easy to spread after scratches and cause the coating to peel off. So it has a short service life. But it will be much cheaper.

2. Color Coated Galvanized Coil (PPGI Coil)

It uses galvanized steel as base metal, including hot-dip galvanized sheets and electro-galvanized sheets. It is the most popular type of color coated steel, especially using hot-dip galvanized steel as the base material. This kind of steel coil is protected by zinc layer and organic coatings to prevent rusting. Because the zinc layer of the electro-galvanized sheet is thin, it is not suitable for outdoor uses. But because of its smooth surface and beautiful appearance, it is popular in interior decoration, steel furniture, home appliances, etc.

3. Colour Coated Galvalume Coil (PPGL Coil)

Obviously, this kind of color coated steel coil uses galvalume steel as the substrate. It features excellent corrosion and heat resistance. And its heat reflectivity is greater than 0.75, which is an ideal building material.

When purchasing color coated coil, you need to decide on the base metal first according to the use purpose and your budget. You can contact us for more details.

Prepainted Steel Coating Process

The coating process is the process by which a steel coil is coated continuously. The steel coil will go through uncoiling, welding, press rolling, inlet looping, pre-treatment (including chemical degreasing and chemical conversion), primer coating, drying, cooling, finish coating, drying, cooling, outlet looping, and coiling. Below is a flow chart for your reference.

Through the coating process, both sides of the steel coil are coated twice. Generally, the back coating thickness is 5-14 μm and the top one is 11-35 μm, which can be customized according to your needs. Below is a picture showing the coating structure.

Color Coated Steel Coil Price

The colour coated coil rate starts from $500 to $1,100 per ton on the market. In fact, the color coated steel coil price is influenced by many factors, such as the substrate, thickness, color, paints, the thickness of the painting, printed pattern, painting methods, etc. We suggest choosing the one that suits your needs and budget the best, rather than the price.

1. Substrates

According to the substrate, there are 3 kinds of color-coated steel coils to choose from, namely, cold-rolled steel (CR), galvanized steel (GI), and Al-Zn-coated steel (GL). Among them, CR is the cheapest one, but its corrosion resistance is not as good as that of GI or GL. Commonly, it is often used as an interior lining panel, lamp, etc. While PPGL is expensive, it is a great building material because of its great corrosion resistance and reflectivity. Below is a video for your reference.

2. Paintings

The commonly-used coatings include polyester (PE), silicone modified polyester (SMP), high durability polyester (HDP), and polyvinylidene fluoride (PVDF). PVDF is more expensive than others, while its physical properties are also much better. Also, it is suggested to choose the paint according to the different use environments.

Items Cost Durability Colors Film Integrity UV Resistance Chalking Resistance Dirt Resistance
PE Low Good Rich Excellent Medium Good Poor
SMP Medium Good Rich Good Medium Good Medium
HDP Medium Very Good Rich Good Very Good Very Good Good
PVDF High Excellent Limited Good Excellent Excellent Good

3. Main Painting Methods

1. Paint the top surface twice, and the back surface once. Bake twice. The single-layer back paint has poor resistance to corrosion and scratch, but it has good adhesion. So it is ideal for sandwich panels.

2. Both the top and back sides are painted twice and baked once. The back paint has good corrosion and scratch resistance and good adhesion. Therefore, it is suitable for single-layer corrugated sheets and sandwich panels.

3. Paint the upper and lower surfaces twice and bake twice. It has great resistance to corrosion and scratch and good workability, but poor adhesion. So this kind of steel coil is used for corrugated sheets, but is not suitable for sandwich panels.

You can choose painting structure and painting types according to the uses of the color coated steel coil. If you want more details, please let us know.
