Product Features & Benefits
- Enhanced Corrosion Resistance: The primer back coat acts as a barrier against moisture and chemicals, significantly reducing the risk of rust formation on the back side of the panel. This is critical for refrigeration panels that experience condensation and temperature fluctuations.
- Superior Adhesion to Insulation: The specially formulated primer ensures strong bonding with polyurethane foam and other insulation materials, preventing delamination and maintaining panel integrity over time.
- Excellent Formability: Our PPGI coil can be easily cut, punched, and bent without cracking or peeling the coating, making it suitable for complex panel profiles and custom fabrication.
- Consistent Thickness & Flatness: Advanced rolling and coating lines guarantee uniform thickness and flatness across the entire coil, reducing waste and improving panel assembly efficiency.
- UV & Weather Resistance: The top coat offers high resistance to ultraviolet radiation, ensuring long-lasting color retention and surface integrity even in outdoor or semi-outdoor refrigeration installations.
- Thermal Insulation Support: The combination of steel substrate and reflective coating helps minimize heat transfer, contributing to the energy efficiency of refrigeration panels.

Frequently Asked Questions (FAQ)
-
What is the difference between a standard PPGI coil and one with a primer back coat?
The primer back coat provides an additional layer of protection on the reverse side of the steel, improving adhesion to insulation foam and preventing corrosion from condensation. It is essential for refrigeration panels where the back side is exposed to moisture. -
Can I order custom colors for the top coat?
Yes, we offer customization according to RAL color standards. Please provide your desired color code, and we will confirm feasibility and minimum order quantity. -
What thickness and width are most commonly used for refrigeration panels?
Typical thicknesses range from 0.4mm to 0.8mm, and widths from 1000mm to 1200mm. However, we can produce up to 1.2mm thickness and 1250mm width based on your specific panel design. -
Is the product suitable for both indoor and outdoor refrigeration units?
Yes, the top coat can be selected with UV-resistant properties (e.g., PVDF or HDP) for outdoor applications. For indoor use, standard polyester coating is sufficient. -
What packaging do you use for coils to prevent damage during transit?
Each coil is tightly wrapped with waterproof paper, plastic film, and steel strapping. Additional wooden crating or pallet packaging is available upon request for extra protection. -
Do you provide samples before bulk order?
Yes, we can provide small samples (e.g., A4 size sheets) for quality evaluation. The sample cost is negotiable and may be refunded upon large orders. -
Can you supply coils with both sides coated (primer on both sides)?
Our standard product has primer back coat only. For double-sided coating, please contact us to discuss custom specifications. -
What is the lead time for a typical order?
Lead time depends on the quantity and customization. For standard specifications, it is usually 15-25 working days after order confirmation. We will provide a precise schedule upon inquiry.
We invite you to contact Hemaokang Steel for a quotation or more technical details. Our team is ready to support your industrial refrigeration panel projects with high-quality PPGI coil and reliable service. Let us help you build panels that perform better and last longer.
