Which component is not typically found in the structural design of a container?

In the context of intermodal container design, a fundamental aspect is understanding the structural components that contribute to a container's integrity and functionality. The correct response highlights that moving wheels are not a typical feature of standard shipping containers.

Shipping containers are primarily designed for stacking, strength, and protection of cargo, featuring elements like door seal gaskets to ensure water resistance, rain gutters to direct water away from door seams, and three-point latches to secure the doors tightly. These components work together to provide durability, easy access, and protection against the elements during transport and storage.

In contrast, moving wheels are not a standard part of the structural design of shipping containers, which are meant to be transported using flatbed trucks, ships, or trains, rather than being wheeled around independently. Therefore, the presence of wheels would not align with the intended use and structural integrity of a container.
