In the evolving landscape of refrigerated transportation and cold chain logistics, the demand for durable, hygienic, and thermally efficient materials has never been higher. Whether you are manufacturing a new refrigerated truck box or retrofitting an existing fleet, the choice of surface material directly impacts the longevity and performance of your asset. We are proud to present our premium range of GRP Panel with Gel Coat, available in a versatile roll format. This product is engineered specifically for the rigorous demands of modern transportation, providing a seamless, robust, and corrosion-resistant lining for polyurethane (PU), extruded polystyrene (XPS), or expanded polystyrene (EPS) composite panels.
Our GRP Panel with Gel Coat is not just a standard fiberglass sheet; it is a specialized solution designed to bridge the gap between structural integrity and operational hygiene. Available in four critical thicknesses—1.5mm, 2mm, 2.5mm, and 3mm—and in classic White and Grey finishes, this product ensures that your Refrigerator Truck box maintains optimal temperature control while resisting the wear and tear of daily loading and unloading.
The transportation of perishable goods requires a Truck Box that can withstand extreme temperature variations, physical impacts, and moisture ingress. Traditional materials like aluminum can dent and corrode over time, while painted steel is prone to chipping. Our GRP Panel with Gel Coat for Truck Box solutions offer a superior alternative. The integrated Gel Coat layer provides a high-gloss, UV-resistant, and waterproof surface that acts as a protective barrier against chemicals, cleaning agents, and scratches.
When you choose our GRP Panel with Gel Coat for Refrigerator Truck applications, you are investing in a material that ensures longevity, reduces maintenance costs, and improves the overall hygiene of your cargo hold. The smooth surface of the White GRP Panel with Gel Coat or Grey GRP Panel with Gel Coat minimizes bacterial growth and allows for quick and efficient cleaning, making it the gold standard for food and pharmaceutical transport.
One of the most significant advantages of our offering is the format: GRP Panel in Roll with Gel Coat. Unlike rigid flat sheets that are limited by standard sizes, the roll format allows for unprecedented flexibility in manufacturing. Customers can easily unroll the fiberglass laminate and cut it to exact lengths according to their specific requirements. This flexibility is essential for forming continuous, seamless bonding with the core insulation material.
To cater to different structural requirements and weight considerations, we offer four distinct thickness grades. Each grade has been optimized to provide a specific balance of strength, weight, and thermal resistance.
The 1.5mm GRP Panel with Gel Coat is the lightest option in our range. It is ideally suited for applications where weight reduction is the primary concern, such as in internal linings or partition walls within the Truck Box. Despite its thin profile, it offers excellent impact resistance and surface protection.
The 2mm GRP Panel with Gel Coat represents the "Goldilocks" zone for many trailer and truck box manufacturers. It offers a perfect balance between robust protection and manageable weight. This thickness is the most popular choice for standard refrigerated truck box side walls, where daily handling and loading impacts are moderate.
For high-traffic floor areas or heavy-duty Refrigerator Truck sidewalls, the 2.5mm GRP Panel with Gel Coat is the preferred choice. The added thickness enhances structural rigidity and reduces the risk of delamination under stress. This grade is particularly effective when bonded to thicker core materials.
The 3mm GRP Panel with Gel Coat is the pinnacle of durability. Designed for the harshest environments, such as deep-sea reefer containers or heavy-duty floor decks, this thickness provides unmatched mechanical strength. If your Truck Box faces extreme impacts from forklifts or heavy pallets, the 3mm GRP Panel with Gel Coat will ensure your investment is well protected.
We understand that aesthetics and functionality go hand in hand. Therefore, we offer two primary color variants:
White GRP Panel with Gel Coat: The standard choice for commercial refrigerated trailers. The bright white finish reflects light, improving visibility inside the Truck Box. Additionally, it is highly effective at highlighting dirt and debris, ensuring that cleaning standards remain high. The White GRP Panel with Gel Coat offers a clean, professional look that is synonymous with food-grade safety.
Grey GRP Panel with Gel Coat: The Grey GRP Panel with Gel Coat is often favored for industrial or heavy-duty applications where dirt and scuffs are more likely. The gray hue effectively conceals minor scratches and dust, reducing the frequency of deep cleaning needed to maintain a pristine visual appearance. It is also an excellent choice for companies who want to distinguish their fleet or for use as a floor lining to contrast with white walls.
Both the Grey GRP Panel with Gel Coat and the White GRP Panel with Gel Coat feature the same high-quality Gel Coat surface finish, ensuring that your choice is purely based on operational preference without compromising on performance.
Our GRP Panel in Roll with Gel Coat is produced using a continuous lamination process. This manufacturing technique ensures consistent thickness, zero pinholes, and uniform fiber distribution across the entire length. Because it is supplied in rolls, the material can be fed directly into automated sandwich panel manufacturing lines. This allows for high-speed production of PU, XPS, or EPS composite boards without the need for joining flat sheets, thereby eliminating weak points.
The roll format is specifically designed to help clients cut the material to required lengths for bonding with core insulation. When you produce the sandwich panels, you lay down the fiberglass skin, apply the expanding polyurethane foam or place the XPS/EPS sheets, and then apply the top GRP Panel with Gel Coat. This creates a powerful structural bond that is integral to the thermal efficiency of the Refrigerator Truck.
The Gel Coat surface is more than just paint; it is a specialized resin layer that provides superior resistance to UV radiation, water absorption, and chemical attack. Unlike conventional paints that peel or crack under thermal cycling (from -40°C to +80°C), the Gel Coat remains permanently bonded to the fiberglass substrate.
High Tensile Strength: Fiberglass reinforcement ensures that the panel can withstand high tensile and flexural loads.
Hygienic Surface: The non-porous nature of the Gel Coat makes it resistant to mold, mildew, and bacteria, which is critical for food-safe transport.
Thermal Insulation: By acting as an excellent thermal barrier, the panel reduces thermal bridging, ensuring the internal temperature of the Truck Box remains stable.
Waterproof: The Gel Coat layer provides an impermeable barrier that prevents water ingress, protecting the underlying insulation core from moisture degradation.
Corrosion Resistance: Unlike metallic surfaces, our GRP Panel with Gel Coat will not rust or oxidize, ensuring a longer service life.
Q: What are the standard roll lengths and widths available for the GRP Panel in Roll with Gel Coat?
A: While we can customize to meet specific project requirements, our standard rolls typically range from 60 meters to 120 meters in length. The width generally varies between 1.2 meters and 2.5 meters. We recommend contacting our technical team to determine the optimal dimensions for your specific Truck Box manufacturing or repair needs.
Q: How do I cut the GRP Panel in Roll with Gel Coat without damaging the surface?
A: The material can be efficiently cut using standard circular saws equipped with a fine-toothed carbide blade. For smaller applications, heavy-duty shears can be used. It is crucial to support the material adequately to prevent cracking at the cut line. Because it is in a roll, you can pre-cut the sheets to your required lengths before applying them to the PU, XPS, or EPS core.
Q: Can I use the 3mm GRP Panel with Gel Coat for the interior floor of a refrigerated truck?
A: Absolutely. The 3mm GRP Panel with Gel Coat is specifically recommended for floor applications due to its high impact resistance. It provides a durable skid-resistant surface capable of handling heavy forklift traffic, provided the underlying structural substrate is adequately supported.
Q: What is the temperature range for the GRP Panel with Gel Coat for Refrigerator Truck applications?
A: Our panels are engineered to perform consistently in extreme cold chain environments. They can withstand continuous operating temperatures from -40°C to +80°C. This makes them perfectly suitable for transporting frozen goods as well as warm loads without warping or delaminating.
Q: Is the White GRP Panel with Gel Coat easier to clean than the Grey GRP Panel with Gel Coat?
A: Both surfaces are non-porous and equally easy to clean. However, the White GRP Panel with Gel Coat makes dirt more visible, ensuring thorough cleaning is visually assured. The Grey GRP Panel with Gel Coat is beneficial in areas where scuffs are frequent, as it maintains a cleaner appearance between washes.
For optimal results, ensure that the core material (PU, XPS, or EPS) is free from dust and moisture before laminating. We recommend using a high-quality structural adhesive that is compatible with fiberglass. When applying the roll material, ensure consistent pressure to avoid air bubbles.
When processing PU foam, the GRP Panel with Gel Coat acts as the ideal skin. The chemical reaction of the curing foam can actually create a strong chemical bond with the fiberglass backing, creating a monolithic structure.
For XPS or EPS cores, proper adhesive selection is vital. Use a two-component polyurethane adhesive or a specialized resin to ensure the skin does not delaminate under thermal stress.
While our standard products are available in 1.5mm, 2mm, 2.5mm, and 3mm thicknesses, we can modify the fiberglass mat weight and resin formulation to enhance specific properties, such as fire retardancy or increased impact resistance. The GRP Panel with Gel Coat for Truck Box can also be customized with specific textures or embossed patterns to improve grip on floor surfaces.
