The two oil crises in the 1970s promoted the automobile industry to improve fuel economy. After the mid-1980s, protecting the environment that humans live and depend on has once again promoted the automobile industry to improve fuel economy and emissions
Studies have shown that for every 10% drop in car quality, fuel consumption drops by 8% and emissions drop by 4%. In the "Thirteenth Five-Year Plan", my country will achieve the low-carbon goal of an international commitment to reduce carbon emissions per unit of GDP by 40% to 50% compared to 2005. As an effective means of energy saving and emission reduction, automobile lightweight has become an automobile. One of the important directions of industry development.
A truck is mainly composed of a front and a carriage. The best way to achieve lightweight trucks is to start with the carriage. The traditional carriages are mainly made of iron sheet and glass steel, which are heavy in quality, which makes the vehicle fuel consumption high and increases the transportation cost. What materials can replace What about this type of traditional carriage?

The new type of honeycomb structure sheet meets this requirement. The glass fiber reinforced polypropylene honeycomb composite panel (HolyPan) produced by Huaju uses a glass fiber polypropylene blended braid as the panel and a thermoplastic honeycomb core material as the core, which is laminated by professional machines. It has the advantages of light weight, high strength, waterproof, moisture-proof and corrosion-resistant.
Example: Comparison of traditional car materials and HolyPan
| Materials | Thickness | Kg/㎡ |
HolyPan | 25mm | 4.38kg |
| FRP honeycomb panel | 22mm | 8kg |
| Steel | 1.2mm | 9.36kg |


The weight of the holypan carriage of the same volume is only a little more than half the weight of the iron box, and it is much lighter than the glass steel plate.

The honeycomb panel is applied to the compartment to make the compartment larger, lighter, and increase the loading weight while reducing transportation costs; the surface of the compartment is flat and smooth, the color of the compartment can be customized, and the box body advertisement is more smooth and atmospheric; In terms of safety, due to its excellent pressing technology, Huaju Board makes the compartment more airtight. Due to the special honeycomb structure, it can disperse the force and make it have good impact resistance.

The dry trucks produced by Huaju adopt a plate structure, which is easy to assemble and convenient for transportation and installation by customers who are far away. The interior of the carriage can also be customized with track floors, cargo hooks, card slots and other multi-functional compartment panels
