What's the Difference between Portable Storage, Conex Containers, or Sea Cans?


Whether you’re looking for conex containers, sea cans, or portable storage, Mobile Mini has a storage solution for you. All of these terms are similar and can be used interchangeably when talking about Mobile Mini storage.


Portable storage containers, also known as conex containers, are used to store personal or professional items like files or equipment. Why the different names? History and the use of the containers has played a part when it comes to the terms. The term conex box, shortened from container express, first started during World War II when the Army shipped cargo in them. The name stuck after that. Sea cans is also another term for conex containers which was coined since these containers traveled by sea. 


Each term is unique in their history but can be used to describe portable storage containers. To learn more about portable storage containers, conex containers, or sea cans, contact Mobile Mini today.
