It would indeed be exceptionally strong; these are made to fill, then stack six or more high! I saw one where he stacked two on one side, and one, set at a distance, on the other. Ran steel beams across the opening, and glazed the new roof formed, with hinged vents that opened by motor . Tiled Concrete follr, and rolling shades formed a unique space, with solar panels on top of the double side.
40 and 20 foot lengths; and the high containers are 9 1/2 foot tall (Vs 8 Foot) I am opting for the tall 40 foot units. The recommended foundation is railroad ties, which will allow me to make a retaining wall on the low side, and fill it from the high side, to level things.
very informative @smithlabs and the 9 1/2 ft ones would be ideal but don't railroad ties eventually rot away?
They last for 50 years on the railroad, and I won't load them as hard. So yes, but someone else will need to fix it, LOL!
I plan on tying in the building on the load points where they stack the upper contailers. When the rest of the building is done, I will cut doors in the sides for inside access!
