The Stellar Story
Built to Be Stellar
Setting the Standard Since 2006
Universal Storage Containers® (USC)—now home to the Stellar Storage Container™ brand—has led the portable storage industry for nearly twenty years, launching innovations that have shaped how the world stores and moves goods.
With over 500,000 containers in use worldwide and a presence in both domestic and international markets, we are proud to be the trusted name in portable storage solutions. We don’t just build containers—we build solutions that move businesses forward.
We believe in long-term partnerships—putting people over profit and always asking, “How can we make this better for our customers?” From engineering and manufacturing to customer service and global distribution, our commitment to excellence drives everything we do.
Now, under our bold new name—Stellar—we’re raising the bar even higher. Because when you’ve led the pack for nearly two decades, the only way forward is up.
The Original Innovators
ISS Best of Business
USC launched the world’s first foldable portable storage container, setting a new standard in convenience, durability, and ROI. That same spirit of invention fuels everything we do today—from our award-winning Z-Box® to rapid-deploy Uplift™ Shelters. Our industry leadership has been recognized with the Inside Self-Storage (ISS) “Best Portable Storage Container” Award for 15 consecutive years (2011–2025).
Why Stellar
2025: Reaching for the Highest Standards
The name Stellar reflects our core mission: to reach for the highest standards in everything we do. Whether it’s improving product performance or exploring new solutions, our goal remains constant—deliver Stellar quality, Stellar service, and Stellar results.
Our rebrand to Stellar in 2025 highlights the unmatched strength, durability, and reliability of our containers, all while keeping the trusted USC name behind our continued innovation.
We’re constantly asking:
“How can we do this better? What else do our customers need?”
And then—we build it.
Stellar reflects our commitment to quality that’s built stronger to last longer, and a service mindset that always puts people over profit.
