Container corner castings (commonly known as corner pieces or corner castings) are key components in container structures, and their functions mainly include the following aspects:
### 1. **Load-bearing and support**
- Corner castings are located at the eight top and bottom corners of the container, and are the main load-bearing nodes of the container body, bearing the weight of the container itself, the cargo load, and the pressure of the upper container when stacked.
- During lifting, transportation or stacking, the corner castings directly bear the external force to ensure that the force is evenly distributed and avoid deformation of the container body.
### 2. **Lifting and handling**
- Corner castings are designed with standardized holes (in accordance with ISO standards) and can be quickly connected with lifting equipment, twist locks or handling equipment (such as cranes, forklifts) to achieve safe and efficient lifting and fixing.
- Top corner pieces are used for top lifting, while bottom corner pieces are used to fix the container to the vehicle, ship or chassis.
### 3. **Stacking and Locking**
- The interlocking and locking devices (such as twist locks) of the corner castings ensure the stability of the stacked multi-layer containers to prevent sliding or overturning.
- In ship, rail or truck transportation, corner castings are the basic connection points for fixing containers.
### 4. **Standardization and Compatibility**
- The size and strength of corner castings strictly follow international standards (such as ISO 1161) to ensure that containers from different manufacturers can be used universally and adapt to global transportation equipment (such as ships, trucks, and rail vehicles).
### 5. **Protect the Container Structure**
- As the outermost reinforcement component of the container, the corner castings bear the brunt of collisions or impacts, absorb energy, and reduce damage to the side walls and door panels of the container.
### 6. **Safety and Certification**
- Corner castings must pass strict strength tests (such as tensile and compressive tests) to ensure compliance with international safety regulations, which is a necessary condition for containers to obtain inspection and certification (such as CSC certification).
### Additional explanation:
- **Material**: Usually high-strength cast steel (such as SCW480), taking into account toughness and corrosion resistance.
- **Design**: The surface is rust-proofed (such as galvanized), and the interior is welded with the container's columns, beams and other structures to form an overall frame.
In short, corner castings are the core components of standardized container transportation, which directly affect loading and unloading efficiency, transportation safety and container life.
