If your door is truly two quarter-inch steel plates, I suspect it’s impervious to any non-armor-piercing small-arms round.

Certainly impervious to any pistol round.

I looked at the end side of the door (end side where it closes) and could see the end of each plate, thought each plate was 1/4 inch, but measured it to be sure.

Thanks for your reply.
