Stonehenge survived thousands of years due to the sheer size and weight of the material. Compared to other building materials of today, shipping containers are durable, modular, and transportable. They are low maintenance steel structures resistant to hurricanes, fires, termites, water, and salt damage. There are about seventeen million inter modal containers. Here at MODS International, many are finding ways to convert these sound structures into quality buildings for a wide array of uses.
