Re: lets talk about shipping or sea containers
Having dealt a great deal with these I can offer a bit of advice here. First they are quite strong and you can bury any of the once with ribs without issue. As for buying one if you plan on using it in cold weather or underground I highly suggest you buy a ex refer unit. The refer ones will run you about the same price sans the refer itself ( refer is the refrigeration unit that is installed in the from of the container ) so you do loose about 2 foot of space but they are very well insulated between the walls and if buried the walls will not sweat and if used outside as my camp in Md was a very small wood stove will heat the whole 40 foot container and keep it plenty warm all night with 2 med logs. If the walls of the container are fiberglass or non ribbed then it is a RAIL container and NOT suitable for putting underground. They do not have the strength. Sea containers are made to be able to handle being stacked 30 plus high loaded on top of each other the rail containers are made to be stacked 3 high at the MOST..
