 FRP: A Revolutionary Material for Cold Chain Transport

Fiberglass Reinforced Plastic (FRP), with its core composition of resin reinforced by glass fibers, combines lightweight strength, corrosion resistance, and superior thermal insulation, making it an ideal material for refrigerated truck manufacturing. Compared to traditional metal materials, its density is only 1/4 to 1/3 that of steel while bearing equivalent load capacity. Moreover, through structural design, it achieves a “zero-metal thermal bridge,” fundamentally resolving energy consumption and frost formation issues in refrigerated trucks.

 Core Advantages of FRP Refrigerated Trucks: Dual Breakthroughs in Technology and Performance

1. Ultimate Thermal Insulation, Drastically Reduced Energy Consumption
   The FRP sandwich structure can incorporate polyurethane (PU) or expanded polystyrene (EPS) insulation layers, with thermal conductivity as low as 0.02–0.03 W/(m·K). Combined with seamless welding technology, the heat leakage rate of the compartment is reduced by over 40% compared to metal bodies. For example, a 30-cubic-meter refrigerated truck with an FRP body can save approximately 12,000 liters of fuel annually, reducing carbon emissions by 30 tons.

2. Lightweight Design, Enhanced Loading Efficiency
   For the same volume, FRP compartments are 300–500 kg lighter than steel compartments, equivalent to carrying 30–50 additional boxes of fresh produce per trip. Field tests by a European cold chain logistics company showed that after switching to FRP refrigerated trucks, single-vehicle transport efficiency increased by 15%, while logistics costs dropped by 8%.

3. Corrosion and Aging Resistance, Adaptable to Extreme Environments
   The chemical stability of the resin matrix and glass fibers ensures performance remains stable in salt spray, acidic, and alkaline environments. For instance, in seafood transport, FRP compartments treated with food-grade gel coats resist seawater spray erosion, achieving a service life of over 15 years—twice that of ordinary metal compartments.

4. Food-Grade Safety, Effortless Cleaning
   The smooth, non-porous surface complies with international food contact material standards such as FDA and EC 1935/2004, preventing bacterial growth and odor retention. The modular design supports full-compartment high-pressure water jet cleaning, improving cleaning efficiency by 50% compared to metal compartments and meeting EU HACCP certification requirements.
