6 Unique Framing Systems

At the heart of every modular wall system is the metal stud framing. Not only does this provide the structural integrity for the entire office or enclosure, but it also makes the system relocatable, attractive, and easy to assemble and wire. With six unique framing systems including our SteelSpan, "all-in-one" wall system, PortaFab can provide the right solution for your application.
