Color Coated Steel Coil

PPGI steel coil Product Introduction

Color Prepainted Galvanized PPGI Steel Coils is a product made of cold rolled steel plate and galvanized steel plate by surface pretreatment (degreasing, cleaning, chemical conversion), continuous coating (roll coating), baking and cooling. Coated steel sheet has light weight, beautiful appearance, good corrosion resistance and can be processed directly. It provides a new raw material for construction, shipbuilding, vehicle manufacturing, household electrical appliances, electrical industry, etc. It has played a good role in replacing wood with steel, efficient construction, energy saving, pollution prevention and other good results

According to our experience, the hot-selling colors for roofing or wall panels include cement grey (RAL 7033), signal blue (RAL 5005), traffic red (RAL 3020), moss green (RAL 6005), colza yellow (RAL 1021), wine red (RAL 3005), etc. While pattern coils are very popular for ceiling, door, or interior decoration. It all depends on your needs and preference. If you want other colors or patterns, please contact us for a custom design.

The color could be customized according to your requirements

Note: The actual color may differ slightly due to the different coating materials, light, etc. But we promise to use the paint as agreed upon in the contract.

Pre-painted steel coils can be slit, sheared, and profiled for different uses, for example,

1. Construction, for example, roofing, interior, and exterior wall panel, ceiling, partitioning walls, etc.

2. Transportation, such as decorative panels of cars, trains or ships, containers, etc.

3. Home Appliances, mainly used to make shells of refrigerators, washing machines, air conditioners, etc.

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.

Prepainted Gi Steel Coil 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.

The colour coated coil rate starts from $500 to $1,300 per ton on the market. In fact, the color coated steel coil price is influenced by many factors, such as the substrate, thickness, color, coating, the thickness of the coating, printed pattern, 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 interior lining panel, lamp, etc. While PPGL is expensive, but it is a great building material because of its great corrosion resistance and reflectivity. Below is a video for your reference.

2. Coatings

The commonly-used top 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.

How to Choose Prepainted Steel Coil?

There are many factors to consider before purchase, such as the substrate, coating, thickness, cost, etc. Below are some tips for your reference.

1. Select the appropriate one for the uses and purposes

It will be very different for different uses. You need to take the corrosion of the use environment, expected service life, and durability into consideration. It matters how to choose the substrate, thickness, and coating. So inform us where and what you will use the color coated coil for, our professional sales team will offer suitable options.

2. Pay more attention to the product quality

There are many color-coated steel coils on the market. Some are very cheap. But you need to pay more attention to the quality rather than the price. If possible, you can ask for samples for reference or visit the factory on-site.
