Temperature-sensitive commodities need properly insulated trucks to provide the cold chain. A top-notch PUF body manufacturer sees to it that reefer trucks are provided with the most effective insulation material to preserve fresh products. Three of the popular insulation panel materials used in cold trucks in India are PPGI (Pre-Painted Galvanized Iron), GRP (Glass Reinforced Plastic), and MS (Mild Steel). Let us discuss their characteristics, advantages, and applications.
PPGI Panels for Reefer Trucks
PPGI panels are commonly used for reefer trucks because they are resistant to corrosion and can last longer. PPGI panels have a coating of paint on them that stops rusting and increases their longevity.
Advantages of PPGI panels
- Lightweight and convenient to manage
- High corrosion resistance
- Even surface for smooth cleaning
- Effective thermal insulation capability
But although PPGI panels are strong, they are not as impact-resistant as some other products. They should be maintained periodically to avoid getting dented or scratched.
GRP Panels for Reefer Trucks
GRP panels consist of reinforced plastic, so they are very light and extremely resistant to damage from the outside. They are commonly used in refrigerated trucks in India due to their high insulation capabilities.
Advantages of GRP panels
- Extremely tough and impact-resistant
- Non-corrosive and weatherproof
- High-quality thermal insulation
- Low maintenance requirements
GRP panels give a smooth and seamless finish, which makes them suitable for food-grade use. They also assist in reducing weight, which increases fuel efficiency in reefer trucks.
MS Panels for Reefer Trucks
MS panels, manufactured from mild steel, are widely employed for MS reefer trucks owing to their toughness and longevity. MS panels are strong but need to be properly maintained to avoid rust and corrosion.
The key advantages of MS panels
- Very strong and long-lasting
- Affordable and easily accessible
- Best suited for heavy-duty use
- Good heat insulation when used in conjunction with proper insulation layers
The disadvantage of MS panels is that they are susceptible to rust, which can shorten their life if not maintained.
Selecting the Ideal Insulation Panel for Your Reefer Truck
Deciding between PPGI, GRP, and MS panels is your decision. If you require a lightweight, corrosion-proof solution, use GRP.For affordable and durable panels, you may choose PPGI. If strength and hardness are your main concerns, then MS reefer trucks using mild steel panels are the best.
Conclusion
Choosing the ideal insulation material for refrigerated trucks in India is key to keeping the cold chain intact and prolonging the lifespan of the vehicle. Your best guide in this selection process can be a good PUF body manufacturer. With or without GRP’s lightweight efficiency, PPGI’s ruggedness, or MS panels’ strength, you will have an ideal insulation to improve the performance and efficiency of your reefer truck.
