What type of deformation requires the repair of rear corner posts?

The type of deformation that necessitates the repair of rear corner posts is outward deformation. When the rear corner posts of a container experience outward deformation, it typically means that the integrity and structural alignment of the corner sections have been compromised. This can occur due to improperly stacked or excessively heavy cargo, leading to bulging or bending away from the container's original shape.

Outward deformation affects the strength and stacking capabilities of the container, making it essential to address such issues to restore the container's structural integrity. Proper repair ensures that the corner posts can effectively support loads in a safe manner, which is critical for maintaining the overall safety and usability of the container.

Inward deformation, while also a concern, primarily affects different aspects of the container's functionality. It might not always involve the need for corner post repair since it can sometimes be managed through other corrective measures within the container's structure. Therefore, focusing on outward deformation helps pinpoint specific repairs needed to ensure the container meets safety standards and operational requirements.
