PSG and VitalSpace: Modular innovation that’s reshaping job sites

In the world of industrial construction, every second counts—and so does every square foot of your site. That’s why Portable Solutions Group (PSG), a leader in modular access control and job site enclosures, has taken a major step forward by joining forces with VitalSpace, a rising modular platform built for essential industries.

This move brings PSG’s trusted solutions—like their patented MAC turnstile portals, custom modular restrooms, and engineered enclosures—under the same banner as SteelCell, the nation’s top manufacturer of prefabricated steel units for the justice system. Together, they form a robust network of modular experts operating under the VitalSpace brand.

“This partnership lets us keep doing what we do best—solving real problems on real job sites—with even more support behind us,” said Rob Slagel, Founder of PSG. “We’ve always been proud of how our products improve safety, comfort, and accountability in the field. Now, with VitalSpace, we’re able to scale that impact and bring modular innovation to even more industries.”

For over two decades, PSG has delivered container-based structures that enhance productivity and protection on active job sites across North America. Their solutions are known for being site-ready, durable, and software-agnostic—traits that make them favorites on large-scale construction and industrial projects where speed, compliance, and security matter most.

“PSG is a natural fit for what we’re building at VitalSpace,” said Mike Smith, CEO of VitalSpace. “They bring an unmatched track record and a solutions-first mindset. What excites us most is how aligned we are in our purpose—creating better, more human-centric environments through modular design.”

This alignment is more than just philosophical. Under the VitalSpace umbrella, PSG and SteelCell remain independently operated brands, continuing to lead in their respective sectors. But behind the scenes, they now share access to advanced R&D, centralized operational support, and a culture of continuous learning—all of which translate into faster innovations and more value for customers in construction, healthcare, justice, and beyond.

For PSG’s customers in the construction industry, this means even greater reliability, faster deployment, and expanded capabilities—without sacrificing the personalized service and engineering excellence they’ve come to expect.

Whether it’s controlling access on high-security sites, providing hygienic modular restrooms, or installing temporary office enclosures, PSG is focused on building environments that are safer, smarter, and designed for today’s job site demands. With the support of VitalSpace, they’re now positioned to elevate that standard across every market they serve.

“We’re entering a new era of job site infrastructure,” added Slagel. “Construction teams are demanding solutions that are not just temporary, but intentional—products that perform over time, improve efficiency, and respect the people who use them. That’s what we’ve always delivered. Now, we’re doing it at scale.”
