How many explosive charges does it take for a metal wall?

The title basically tells it :)
How many explosive charges does it take for a metal wall?
I am making a metal house now, and im planning on having alot of doors people need to blow up. Therefore I wonder how many explosive charges the metal walls can take; if they dont take that many, then all my doors are worthless :P
Dont know if there is a thread to ask stuff like this, but I didnt find it. Tried looking it up online but found no answers.

Thanks for all the replies!

the amount of charges would also depend on how much decay has happened to the wall first would it not?
