Who We Are
About Us
Southwest Mobile Storage is a family owned business founded in 1995. Our 11-acre headquarters in Phoenix, AZ features a 90,000 sq ft indoor fabrication facility staffed with more than 40 certified engineers, welders, fabricators, electricians, carpenters and painters bringing over 500 years combined experience specialized in modifying steel containers. This level of facility and expertise is unmatched in the industry.
Our strength for more than 25 years comes from the specialized knowledge and passion of our people, along with serving over 24,000 commercial, construction and residential customers. While the rental side of our business is regional with branches throughout Arizona, California and Colorado, our sales and modification operations are nationwide and becoming global.
As leaders in high-end fabrication of steel containers, we have built thousands of projects from complex customizations for NASA and the US Navy to extensive projects for the City of Los Angeles, GCP Applied Technologies, Helix and Sundt to name a few. Customizing containers goes beyond just doors and windows to us. Whatever you can imagine, we can build without the need to outsource anything. Our certified safety and quality inspection throughout the process means you can expect reliable completion and excellence in steel container repurposing.
Our mobile storage containers and portable offices are rented by small businesses as well as some of the most recognized brands in the world like Amazon, Walmart, Boeing, Universal Studios and more. From service to delivery, we are committed to providing you the best experience and fleet maintained to the highest quality standard—our integrity depends on it.
