Columbia Equipment created the first prefabricated aluminum Shelter back in 1961 ! Columbia Shelters are in use in thousands of locations – in all 50 states – including Alaska and Hawaii, and many other locations all around the world! We design, manufacture, install and maintain shelters. Columbia shelters are considered the most easily installed, weatherproof, vandal-resistant and maintenance-free shelters available. Maybe that is why many of the nation’s leading consultants recommend us.
