Depends on what the armor is made of, of course. In addition, are you assuming an impact perpendicular to the surface or at some angle? At what speed is the round travelling? What is the composition of the round? Armor piercing? Standard lead?
Need more information to make the answer meaningful.

The hardness of the armor and the angle of the bullet impact are the determining factors here. At my club, our bullet traps are made of 1/2" thick AR500 steel, which is hardened to a brinnell hardness of 500. They are set at about a 40 degree angle and can withstand ANY handgun round without any damage to the surface. At a 30 degree angle, it is supposed to be able to handle a 7.62 NATO (.308 Winchester) round.
I suspect that if fired directly at it, it would stop it, but may make deform the surface.
For Armor Piercing rounds, or Kevlar, aluminum or composite armor, then none of this applies.
Sheet metal DEFINITELY will not stop it. 1/2" mild steel will not stop a 7.62 NATO round.

I'm not sure, but my brother has a rifle that shoots the 7.62. I'll go try it with him and see. If I don't come back you will know that sheet metal over the door didn't work and you'll wanna go thicker. See ya later, maybe...
