How to Select High-Quality Semi-Trailers: Key Factors and Recommendations

As a professional semi-trailer export company, we are dedicated to providing our customers with high-quality transportation solutions. Selecting the right semi-trailer not only affects transportation efficiency but also concerns the safety of goods and transportation costs. This article will introduce key factors to consider when selecting a semi-trailer, helping you make the best decision.

1. Main beam

The material of the semi-trailer plate is the foundation that determines the strength and durability of the vehicle’s structure. The two commonly used materials are Q355 and T700, which have different yield strength and tensile strength, making them suitable for different transportation environments.

Q355 Steel: Q355 is a medium-to-high strength low-alloy steel with a yield strength of around 355 MPa and a tensile strength of 500-650 MPa. It has good weldability and high fatigue resistance, making it suitable for general load transportation tasks, especially in mild climates and road conditions. Q355 steel is commonly used in the body structure of standard load semi-trailers due to its high cost-performance ratio.

T700 Steel: T700 is a high-strength alloy steel with a yield strength of about 700 MPa and a tensile strength of 800-1000 MPa. Compared to Q355 steel, T700 offers higher strength and better corrosion resistance, making it suitable for heavy-duty, long-distance transport and harsh environments. T700 steel is commonly used in the design of high-load-bearing semi-trailer beams, able to withstand larger loads and more demanding working conditions. Although T700 steel is more expensive, its excellent performance makes it ideal for applications requiring longer service life and high-strength loads.

2. Common Accessories Brands
High-quality accessory brands are crucial for ensuring the efficient and stable operation of semi-trailers. Here are some recommended brands for key components:

Axle Brands: FUWA and BPW are globally recognized semi-trailer axle manufacturers. FUWA axles are popular for their high cost-performance ratio and stability, while BPW is known for its advanced technology and exceptional durability, making it suitable for high-load and long-duration transportation applications.

Tire Brands: Brands like Triangle (China), Linglong, and Chaoyang are highly reputable in both domestic and international markets. They offer tires with excellent wear resistance and slip resistance, making them adaptable to various road conditions and complex climates.

Landing Gear and Kingpin Brands: JOST is a global leader in semi-trailer landing gears and kingpins, known for their durability and high performance, ensuring stability and safety in various transportation environments.

Choosing high-quality accessory brands can enhance the overall performance of the semi-trailer and ensure long-term reliability under extreme working conditions.

3. Regular Maintenance and Inspections
Regardless of whether you purchase a high-quality semi-trailer or a standard model, regular maintenance and inspections are key to ensuring efficient operation. Particularly for components like axles, tires, braking systems, landing gears, and kingpins, they must be kept in good working condition to prevent safety hazards.

4. Customized Solutions Based on Customer Needs

We offer customized services to meet the diverse transportation needs of our clients. For example, you can select different axles, tires, and main beams based on the characteristics of your goods and the transportation distance.
