Why is the body of a refrigerated truck made of fiberglass?

Glass fiber reinforced plastic, also known as GRP, generally refers to glass fiber reinforced unsaturated polyester resin, epoxy resin, and phenolic resin matrix. Reinforced plastics that use fiberglass or its products as reinforcing materials are called fiberglass reinforced plastics or FRP. FRP is lightweight and hard, non-conductive, with high mechanical strength, difficult to recycle, and corrosion-resistant. It can replace steel in manufacturing mechanical parts, cars, ships, etc. So, what are the advantages of using fiberglass raw materials to manufacture Chongqing refrigerated trucks?



1. The fiberglass refrigerated vehicle body has thermal insulation and impermeability properties: the composite plate of the refrigerated vehicle body is lightweight, not easy to deform, and the plate is compact and seamless. The insulation performance of refrigerated trucks is very good. The panel of the composite board is impermeable, and the rigid polyurethane foam has large closed holes and good water resistance.



2. The fiberglass Refrigerated Truck body also has the characteristics of easy installation, easy cleaning, and corrosion resistance: Jiangnan refrigerated trucks are insulated refrigerated trucks assembled from high-strength aluminum profiles and composite plates. The device is simple and fast, and the assembled insulated refrigerated truck is flat, smooth, seamless, beautiful, and durable. A smooth fiberglass coating helps to remove dirt. The entire panel can be painted with colors according to user needs. It has good stability for media with general concentrations such as atmosphere, water, acid, alkali, and salt, and can maintain the brightness of the appearance for a long time.



3. The fiberglass refrigerated truck body is also easy to repair, and there are no obvious marks after repair.



4. The specifications and dimensions of fiberglass refrigerated trucks can be chosen by oneself, making them convenient and practical.



Of course, the body of an insulated and refrigerated vehicle can also be made of materials such as stainless steel and aluminum alloy, but the price is much higher than that of fiberglass raw materials.
