Maybe it was a construction thing ???
Most race cans I have heard of are either,
Carbony,
Titaniumy,
or
Stainlessy
Would have thought an Iron can would have been a bit on the heavy side
Sorry to hear, but you knew the risks and took em, which is your right to do and in no ways a "told you so" thing. Besides I am sure that the enjoyment of the can is worth £30
