Shipping containers are defined as containers that facilitate the transport and carriage of goods without the need to unload and/or reload the cargo at intermediate points. These containers are large rectangular boxes made of a special corrosion resistant grade of steel and are characterized by high strength and durability. Containers are generally made up of aluminum and steel. The size and type built of each container comply with specifications and regulations formulated by the International Organization for Standardization (ISO). Shipping containers are classified into three main categories, namely dry containers, reefer containers, and tank containers.
