Core Manufacturing Process
- Welding Process: Adopting automatic submerged arc welding technology for continuous welding at the connection between the main beam and crossbeam. Weld penetration depth reaches 6-8mm, without defects such as pores or slag inclusion, ensuring weld fatigue strength and significantly extending service life.
- Painting Process: After degreasing, phosphating, and other pretreatment processes, the trailer body is immersed in an electrophoresis tank for cathodic electrophoresis coating. The coating adheres evenly to the metal surface through electric field adsorption, resisting erosion from rainwater and building material dust, and maintaining long-lasting anti-rust performance.

Main Features
- Main Beam Material: Made of Q345 or T700 high-strength steel, reducing self-weight while improving load capacity. It resists bending and deformation under long-term heavy loads, ensuring transport safety.
- Checkered Steel Floor: The floor is made of anti-slip checkered steel plate with clear and deep textures, increasing friction with cargo and preventing sliding during transport.
- Open Deck Design: The open deck design facilitates loading and unloading from multiple angles using cranes, forklifts, and other equipment, accommodating various cargo shapes and sizes, with flexible and efficient operation.
- Twist Locks: Equipped with 4-12 sets of standard container twist locks that tightly grip container corners, preventing displacement or falling during transport, ensuring stability and safety in container transportation.
- Stanchions: Optional detachable stanchions for transporting logs, pipes, and similar cargo, keeping cargo fixed and preventing rolling or falling.
- Brake System: Equipped with ABS anti-lock air brake system, preventing wheel lock-up during braking, shortening braking distance, improving driving stability on slippery roads, and reducing safety hazards.


Shipping Details
- According to trailer specifications, shipping can be done by container or Ro-Ro vessel. Detachable and vulnerable parts are packed in wooden boxes after being wrapped with shockproof foam, while the whole trailer is covered with waterproof cloth to prevent collision damage during transportation.
- According to customer destinations, transportation methods are arranged through road, railway, sea, or multimodal transport, with full tracking of cargo status to ensure safe and timely delivery.
