The raw materials of container flatbed trailers mainly include the following categories:
1. Steel
Steel is the core raw material of container flatbed trailers and is mainly used in parts such as frames, main beams, side beams and bottom plates. Commonly used steel types include:
- Q345B steel: This steel has high strength and good toughness and is often used in the production of main beams and side beams.
- Q235 steel: It has moderate strength and toughness and relatively low cost and is often used in parts such as side beams.
- 16Mn steel: It is also a high-strength steel that can be used in key parts such as longitudinal beams.
2. Bottom plate material
The bottom plate usually uses anti-slip patterned plates with a thickness of about 3mm. This material not only has good anti-slip properties, but also effectively protects the stability of goods during transportation.
3. Suspension system materials
The suspension system is an important part of the container flatbed trailer. Commonly used materials include:
- Spring steel: Used to manufacture spring suspension systems, with good elasticity and load-bearing capacity.
- Air suspension system: Some high-end models use air suspension system, and its main materials are high-strength rubber and metal parts.

4. Tires and axles
- Tires: Usually use tires with specifications such as 12.00R22.5 or 315/80R22.5, which have good wear resistance and load-bearing capacity.
- Axles: The material of axles is mainly high-strength steel, and common brands include FUWA, BPW, etc.
5. Paint
For corrosion protection and beauty, container flatbed trailers usually use polyurethane paint. This paint has good adhesion and weather resistance, can effectively prevent the body from rusting, and extend the service life.
6. Container locks
Container locks are key components to ensure the safety of goods. They are usually made of high-strength steel and equipped with high-quality lock cylinders.
7. Other parts
- Outriggers: Usually use products from well-known brands such as JOST.
- Brake system: such as WABCO brand, providing reliable braking performance.
- Electrical system: including 24V LED lights, etc.
The selection and quality of these raw materials directly affect the performance, service life and safety of container flatbed trailers.
