The ISO standard shipping containers are designed to make
vertical contact with eachother through corner fittings so when stacked all
vertical load is carried through the corners rather than the walls of the
container.
The number of containers which can be stacked is limited by the strength of the corner posts. The ISO standard tests the containers to a load of 86,400kg (190,486lbs) or the equivalent of eight containers of weight. Higher strength corner fittings can allow stacking up to 12 units high.
