What Is Steel Frame Modular?

Steel frame modular buildings are precision-fabricated structures built in our Houston factory and assembled on-site. They offer unmatched flexibility in size, layout, and finish options—ideal for commercial retail and hospitality spaces, Quick Service Restaurants (QSR’s), industrial structures, and more. This approach also ensures efficient permitting and duplicable franchise templates optimized for fast-build construction projects.
