Structural Integrity & Stud Construction

The heart of any modular building is its framing system and PortaFab's OmniFlex Plus leads the industry. Its stud sections physically connect back-to-back providing a stronger load bearing system than any comparable 3" system. The unique double layer steel studs provide more strength at a lower cost than single layer studs and the rolled ends reduce tear risks during assembly. To assure long life we also utilize high quality materials including rust-inhibiting galvanized, bonderized steel, with baked enamel finish on all exposed metal parts.
Now, you don't have to compromise aesthetics to gain cost-effective advantages of modular construction. Color-coordinated panels, studs, doors and trim bring a professional "front office" finish to OmniFlex 300 Plus modular buildings.
Our Best Value Ever
OmniFlex 300 Plus modular buildings offer quality, appearance and cost-savings that make conventional construction obsolete. Plus, they are completely re-usable, so your modular building can grow with your business.
Compare before you choose any in-plant building. No other construction method can match the uncompromising quality and high-finish appearance of the OmniFlex 300 Plus wall system.
Modular Flexibility
Whenever you need to change your plant layout, your modular building can change with it. Nonprogressive construction makes it easy to expand, modify or relocate these units. So, you save time and money in the future, as well as on your initial modular building investment.
Unlimited Wall Panels
While our Fire & Sound wall panels have earned a reputation for quality, appearance, and performance, we offer a full line of panels to meet your specific requirement. View Standard Panels.
Electrical Functionality
PortaFab's OmniFlex Plus system allows for wiring capabilities on both sides of the stud without affecting the structural integrity of the stud. Removable "snap-in" cover plates allow for easy inspection of raceways. Electrical or communication lines can be added at any time, during or after installation without purchasing additional stud components or cutting into them.
