What deformation depth on any part of the top side rails warrants a repair?

When assessing the condition of container top side rails, any deformation is cause for concern. The top side rails are critical structural components that contribute to the overall integrity and safety of the container. Even minor deformations can signal issues that may compromise the container's ability to bear loads or withstand stresses during transportation and handling.

Deformations can affect how the container stacks and interacts with other containers, as well as how it fits onto transport vehicles. Allowing any deformation without repair could lead to more significant problems down the line, including further structural weakening or compliance issues with container regulations and standards.

Thus, the requirement for repair in the case of any deformation emphasizes a preventive approach to maintenance and safety in container handling. This ensures that all containers remain in peak condition, reducing the risk of failure during operation.
