An engineering assessment offers the following additional technical information as it applies to the 14x14x24" bolted size time capsule, but the information also applies to this unit's size. In answer to why we make our wall thicknesses .075" and not .25" thickness of 304L stainless steel:
"A time capsule buried in dry soil will not experience an even pressure distribution, as it would if it were suspended in a liquid or a gas. With the capsule oriented vertically, the primary loads would be exerted on the top and bottom. Side loads would be insignificant, unless the soil were to become saturated with water and unstable. I assume you are not putting it in that kind of an environment. Our 14x14x24" bolted time capsule can withstand loads in excess of 200 lbs distributed over each of the 14x24" sides without significant deflection. In addition, it can sustain a vertical load well in excess of 10,000 lbs distributed over the top surface."
Preservation Enclosure Kits are available for this time capsule. Consider the 'small' kit 11001 or the 'medium' kit 11002 for this size of time capsule.
