What function does a gusset serve in a container?

A gusset plays a crucial role in enhancing the structural integrity of a container. As a reinforcement feature, it is welded into place to provide support and stiffness to specific areas of the container, especially at points where stress concentrations are likely to occur, such as corners or joints. This reinforcement helps to prevent deformation and increases the overall strength of the container, ensuring that it can withstand the rigors of shipping and handling.

In the context of container design, gussets are often employed to support structural loads and maintain the container's shape over time. Although other options mention different functions, they do not accurately reflect the purpose of a gusset in container construction. Other features, like a door handle, an increase in internal space, or a drainage solution, do not align with the primary function of a gusset, which is specifically to reinforce and stabilize the container's framework.
