TOPOLO offers a variety of fiberglass sandwich panels for dry freight bodies
- To ensure stability and durability during transportation, dry freight bodies must be strong and durable, yet lightweight. This poses significant challenges for the materials used in the box panels. Traditionally, aluminum seems to be the best choice among metals. For example, it can withstand 5 times the impact of steel without failing. It’s also quite lighter than other metals. Actually, the material of dry freight body panels can be further improved by composites if less weight and more strength are demanded.
- Metal is no longer the mainstream, with a growing number of truck and trailer users opting for lightweight yet durable fiberglass composite boxes. TOPOLO is undoubtedly an expert in this field, and our composite materials offer outstanding performance at an affordable price, bringing material and technological innovation to the global transportation market.

Fiberglass Plywood Sandwich Panels
- Plywood is a structure made up of multiple layers of overlapping wooden boards. This structure not only improves the strength of the board, but also increases the utilization rate of wood. The most prominent advantages of using plywood as dry truck box panels are high structural strength, relative ease of processing, and relatively low manufacturing costs. Its disadvantage is that it is prone to moisture, deformation and rot. If not properly maintained, its service life will be greatly shortened.
Fiberglass PET Foam Sandwich Panels
- As a substitute for plywood, PET foam is waterproof, lightweight, high-strength, does not rot, and is easy to process. At the same time, PET foam, as an environmentally friendly and recyclable foam material, is also very consistent with the current green and environmentally friendly development concept.
Flat Fiberglass Polypropylene Honeycomb Panels
- Using PP(Polypropylene) honeycomb as the core material can greatly reduce the weight of the dry cargo truck body. Glass fiber honeycomb panels are both high-strength and lightweight, impact-resistant, waterproof, moisture-proof, and non-deformable. They are very suitable for making the body of dry cargo trucks. Its service life is very long, usually more than ten years.
Non-slip Fiberglass Polypropylene Honeycomb Panels
- Fiberglass honeycomb panels, specifically designed for flooring, have an embossed anti-slip texture on their surface. They are lighter, more anti-slip, and more waterproof than metal or wood flooring, making them the preferred material for lightweight dry cargo truck floors.
Fiberglass XPS Foam Sandwich Panels
- Fiberglass XPS foam sandwich panel is a material that combines thermal insulation and compressive strength. Most dry cargo truck bodies do not need to have thermal insulation properties, but in higher latitudes, it can withstand low temperature tests and maintain moderate stability inside the box.
Fiberglass PP Foam Sandwich Panels
- Extruded PP (Polypropylene) foam core is also a new type of recyclable and environmentally friendly foam. The sandwich panel formed by it combined with the polypropylene skin has high tensile strength and tear strength, and is one of the best lightweight body composite panels.
Recyclable Dry Freight Body Panels
Amid the global low-carbon transition, sustainable development has become a core model for guiding economic development. Its core principle is to achieve a balance between economic growth and ecological protection through efficient resource recycling and environmentally friendly technological innovation. Against this backdrop, highly recyclable plastic materials such as PP (polypropylene) and PET (polyethylene terephthalate) are becoming key enablers of green manufacturing. These materials not only consume low energy during production, but also, thanks to their stable chemical properties and mature recycling systems, achieve a closed-loop “from product to renewable resource.”
“lightweighting + durability + sustainability”
Composite panels made from PP and PET as core materials are now demonstrating significant advantages in dry cargo truck bodies. Through an optimized multi-layer composite process, these panels significantly reduce vehicle weight, improve fuel economy, and maintain environmental performance throughout their entire lifecycle. At the end of the vehicle’s lifespan, these composite panels can be 100% recycled through a specialized recycling process, where they are sorted, melted, and reshaped before being put back into production.
