What is the maximum number of sections allowed in corner posts?

The maximum number of sections allowed in corner posts is three. Corner posts are critical structural components in a dry van, providing stability and reinforcing the integrity of the container's frame. In the context of these posts, having more than three sections could compromise strength and safety.

The design standard limits the corner posts to three sections to maintain a balance between flexibility and structural integrity. This design allows for adequate support while ensuring that the posts can absorb stress from various directions, such as during handling and transport. Using fewer than three sections could lead to insufficient strength, while using more would unnecessarily complicate the design without adding structural benefit.

Therefore, the correct answer reflects the optimal design consideration for strength and functionality within the industry's standards.
