FRP Gelcoat Panels for Truck & RV Bodies
Gelcoat FRP Panels
Factory-direct fiberglass reinforced plastic panels engineered for refrigerated truck bodies, RV sidewalls, and composite sandwich panels. Built to perform - priced to compete.


What Are Gelcoat FRP Panels?
Gelcoat FRP (Fiberglass Reinforced Plastic) panels are composite sheets made from high-quality unsaturated polyester resin reinforced with fiberglass mat or woven fabric, finished with a durable gelcoat surface. Widely used as the outer skin and interior lining for refrigerated trucks, dry freight vans, RV/caravan bodies, and composite sandwich panels.
Lightweight & High-Strength
Density 1.5–2.0 g/cm³ - only 1/4 to 1/5 the weight of carbon steel, yet tensile strength reaches 90+ MPa. Less weight means better fuel economy for your vehicles.
Corrosion & Weather Resistant
Resists water, acids, alkalis, salts, oils, and most organic solvents. No rust, no rot
Excellent Thermal Insulation
Thermal conductivity only 1/100 to 1/1000 of metal - helps maintain interior temperature in refrigerated trucks, reducing energy costs and compressor wear.
Electrical Insulation
Excellent dielectric properties even at high frequencies. Safe for applications where electrical isolation matters - ambulances, mobile clinics, and specialty vehicles.
