What is the interior structure made of?
I’m not sure what the question is, but let me take a stab at it. We do not sell wood studs or sheetrock for finishing out the interior of the building. Standing inside the structure and looking at the walls, you will see the red-iron main frames, red-iron girts, and the back side of the wall panel which will be white (all wall panels are white on the back except for galvalume panels, which are a silver color on both sides). Of course, if you install a vapor barrier, reflective foil, or fiberglass insulation, the facing of this material will cover the wall panels.
