Paint Coating
Base Metal (Galvanized Steel): The core of the coil is galvanized steel, which is steel coated with a layer of zinc to provide corrosion resistance.
Chemical Treatment Layer: This layer is applied to the galvanized steel to improve adhesion of the subsequent coatings and to enhance corrosion resistance.
Primer Coating: A primer coating is applied on top of the chemical treatment layer. This layer further enhances adhesion and provides an additional barrier against corrosion.
Topcoat (Finish Coat): The topcoat is a colored paint layer that provides both aesthetic appeal and additional protection.
Back Coat (Optional): On the underside of the coil, a back coat may be applied.

How long does color coated steel coil last?
It depends on several factors including the quality of the coating, the environment it’s exposed to, and how well it’s maintained.
Under normal conditions, a well-maintained PPGI can last for several decades. In favorable environments, it can even last 20 to 30 years or more. However, in harsher conditions or environments with high levels of moisture, salt, or other corrosive elements, the lifespan may be shorter.
Proper installation, regular inspections, and timely maintenance can significantly extend the life of painted galvanized steel. Additionally, choosing a high-quality coating and following manufacturer recommendations for care and maintenance are important factors in determining the longevity of PPGI.
Keep in mind that while galvanized steel is known for its corrosion resistance, no material is entirely immune to the effects of time and the environment. Regular inspections and maintenance are key to ensuring the longevity of painted galvanized steel.
What is the color coated steel coil price?
It can vary widely depending on several factors including:
1) PPGI steel Thickness
Thicker sheets generally cost more than thinner ones.
2)PPGI steel Coating Type and Thickness
Different coatings (e.g., polyester, SMP, PVDF) and their respective thicknesses will affect the price.
3)pPGI steel Width and Length
Larger sheets will typically cost more than smaller ones.
4)PPGI Steel Quality and Brand
Reputable brands or higher-quality sheets may come at a premium.
5) pPGI steel Market Conditions
Prices can fluctuate due to supply and demand, as well as global market trends.
6) PPGI steel Customization
Any additional treatments or customization may also impact the price.
7) PPGI Steel Quantity
Bulk purchases may come with discounts.
8) Location
Prices can vary by region or country due to factors like transportation costs and local market conditions.
The latest FOB price of PPGI per ton in 2024 is around USD 600 – USD 800.
What is coil coating process?
The coating process for color coated steel coils involves several key steps to prepare and apply the protective and decorative coatings:
1) Surface Preparation:
– Cleaning: The galvanized steel surface is thoroughly cleaned to remove any dirt, grease, or contaminants. This is typically done using a combination of alkaline or acidic cleaners.
– Rinsing: After cleaning, the surface is rinsed to ensure all residues are removed.
2) Chemical Treatment:
– Phosphating or Chromating: The steel is treated with a solution containing phosphate or chromate compounds. This forms a thin, chemical-conversion coating on the surface. This step enhances adhesion and provides additional corrosion resistance.
3)Primer Application:
– A primer coat is applied to the prepared surface. This primer is specifically designed for use on galvanized steel and provides adhesion for the subsequent layers of coating.
4) Application of Top Coat:
– The top coat, which contains pigments for color and additional protective elements, is applied. Different types of coatings (polyester, SMP, PVDF, etc.) may be used depending on the specific requirements.
5) Curing or Baking:
– The coated steel is then passed through a high-temperature curing or baking process. This solidifies and bonds the coating to the surface of the steel.
6) Cooling and Inspection:
– The freshly coated steel is allowed to cool. It is then inspected for uniformity, adhesion, and any potential defects.
What are the advantages of color coated steel?
