What is described as the frame of a container?

The answer identifies the frame of a container as the peripheral structural assembly surrounding one face of the container. In the context of container design, the frame provides essential support and shapes the overall configuration of the container, contributing to its integrity and durability. The frame is crucial because it defines the container’s physical dimensions and serves as the foundation for other components, such as walls and roofs.

This frame typically includes elements such as corner posts and horizontal members that work together to maintain the container's structure under load and during transport. A well-constructed frame ensures that the container can withstand the various stresses and strains it encounters, making it an essential part of container design.

Other options focus on different aspects of container functionality but do not accurately reflect the definition of the frame. For instance, the internal structure refers to features that aid in the safe hold of cargo but do not constitute the frame itself. A protective coating pertains to surface treatments that may protect against corrosion or provide weather resistance but isn't associated with the structural framework. Lastly, the locking mechanism is a functional feature that secures the doors but is not related to the container's overall frame.
