What is the function of the door header in a container?

The function of the door header in a container is to secure the top door cams and ensure structural integrity. The door header plays a critical role in the overall functionality and stability of the container, particularly at the connection points of the doors. By securing the top door cams, it ensures that the doors can close properly and remain airtight and weather-tight when sealed, which is essential for protecting the cargo inside from external elements and maintaining overall container strength. This structural integrity is vital to withstand the stresses of transportation, such as stacking and movement during transit.

Insulation, ease of access, and aesthetic design are not primary functions of the door header. While insulation might be important for specific cargo types, it is achieved through the container’s walls and floor rather than the door header. Access to cargo is typically facilitated by the design of the container doors themselves rather than the header. Aesthetics are generally not a primary concern in the design of cargo containers, which prioritize functionality and safety over appearance.
