Advantages of prefabricated compartments:

The first point is that its structure is very stable, not easy to deform, and its mass is very light.

The second point is that it can save a lot of space, for example, we now drive a car, if we need to load more things, we put it in the trunk. If we use a prefabricated compartment, we only need to make a door on the outside of the box.

The third point is that it can be very good dust and water. Finally, if we put the container in a humid, hot environment, the car will quickly break down, and this prefabricated compartment will not have this problem.
