The iron structure is formed by welding a plurality of steel plates rather than a single steel plate, or is formed to include various reinforcing structures to withstand a considerable size of force. On the other hand, radio waves are reflected from the surface of the metal or absorbed into the iron structure. Because of the characteristics of such radio waves, it is not easy for the radio waves to pass through the steel structure of the container, and electromagnetic shielding phenomenon occurs.
