The materials of commercial vans mainly include the following:
Steel: Steel is one of the most widely used box materials at present. It is strong and durable, affordable and has good load-bearing capacity and earthquake resistance. However, steel is heavy and can easily rust if not treated properly.
Aluminum alloy: Aluminum alloy has low density, high strength and corrosion resistance. It can significantly reduce the weight of the vehicle body, reduce fuel consumption and improve transportation efficiency. In addition, the surface of aluminum alloy can be treated with processes such as anodizing to improve its corrosion resistance. But the price of aluminum alloy is higher.
Stainless steel: Stainless steel is resistant to corrosion, high and low temperatures, has good durability, long life and is easy to clean. However, stainless steel is more expensive and is usually used in situations with higher requirements on the car body.
FRP: FRP is a lightweight and stable material with flame retardant, heat insulation, sound insulation and insulation properties. Its manufacturing cost is relatively low and can meet the needs of lightweight vehicle body. However, fiberglass materials are relatively brittle, easily damaged by collisions, and difficult to repair after damage.
Steel plate: including color steel plate, galvanized plate and plastic plated plate, etc., the production methods include frame type and frameless type. The skeleton type is easy to process and has a low price, and is suitable for small batch production; the skeleton type has higher requirements for processing equipment, but uses less materials and has a lower price.
Aluminum-plastic composite panel: It is composed of aluminum plate and plastic. It has the characteristics of high strength, corrosion resistance, fire prevention, heat insulation, sound insulation and easy maintenance. This is a new type of composite panel material with a price similar to aluminum.
Curtain: The left and right sides of the car body adopt a push-pull curtain structure, which is easy to install and low cost. But its disadvantage is that it is easy to scratch and not fire-resistant.
Advantages, disadvantages and application scenarios of different materials:
Steel: Suitable for heavy-duty trucks and suitable for long-term use in harsh environments.
Aluminum Alloy: Suitable for mid-to-high-end market, suitable for users who have high requirements on vehicle body weight and corrosion resistance.
Stainless Steel: Suitable for occasions with high requirements on the durability and aesthetics of the car body.
Fiberglass: Suitable for occasions where lightweight and heat and sound insulation are required.
Steel Plate: Suitable for low-cost, small-volume production needs.
Aluminum-plastic composite panel: Suitable for occasions requiring high strength and corrosion resistance.
Cord Fabric: Suitable for occasions with strict cost control, but attention should be paid to its durability.
