VersaTube's unique "Slip-Fit" connections simplify the construction process dramatically. It goes back to "swaging" and our patented assembly technique - which allows one steel frame component to easily slip into another steel component, i.e. a rafter section into a peak or a sidepost. With such a builder-friendly design and complete step-by-step assembly instructions, carports can be put together in hours. And garages can be assembled in a weekend.
