In addition to being the fastest way to build permanent quality structures anywhere, Tronco is also a real departure from conventional thinking in terms of building construction.

Tronco’s custom-made components are fast and cost-effective to fabricate and assemble into superstructures (walls, upper floors, roofs). Both the fabrication of components and their assembly can be done almost anywhere, even in the most remote locations, using mobile light-gauge steel/aluminum processing equipment and locally hired helpers. Also, finished buildings may look like old-time classics, depending on type of cladding.

The system is an amalgam of old and new construction methods, combining the time- proven principles of wooden Lincoln log-cabins with sturdy light-weight metallic logs, called "metalogs" (Tronco means "log" in Spanish).

Metalogs are custom-made, at the construction sites, from galvanized strip steel (or aluminum), using mobile tubeforming machines, with connector elements inserted into either end. The metalogs are then put together, much as in the original wooden log-cabin structures, into perpendicular walls, upper floors and roofs of structurally integrated superstructures. The superstructure is then finished in the manner best suited to its end use, with metalogs either conveying a high-tech look to walls, or with metalogs hidden from view.

When metalogs are to be hidden from view, they may receive most any type of cladding. The easiest/fastest option is to use insulated "troncopanels" and cement stucco on walls. Troncopanels made of high-density polystyrene are flat on one side, with the other side shaped as a counterpart of the tubular wall against which they are cement-glued.

Tronco’s usual modus operandi is to license and/or joint-venture with strategic partners into Tronco Regional Entities (TRE's), in charge of superstructure construction, including exterior cladding. A typical such TRE will offer engineering support, dispatch the equipment together with the steel coils and structural plus cladding components needed to build up to three story custom-designed buildings. All of which can be done, with speed and simplicity, in a most user-friendly manner and at a lesser cost than conventional wood/steel frames.
