At first glance, a steel ISO shipping container is a bulky steel box that has one use, shipping goods by ship and train. Southwest Mobile Storage knows that in reality, these strong metal boxes can be versatile and useful with some minor or major custom modifications. The possibilities are endless!


The SMS Fabrication Division can convert a standard ISO steel container into almost any type of custom workspace, storage unit or living space. Entire apartment complexes have been created from customized storage containers.

At Southwest Mobile Storage, a full engineering staff supports our Fabricator-1 Certified Facilities. Certified welders, electricians and quality control inspectors perform the modifications according to the client’s request.
