If these zombies are so superhumanly strong that they can rip off your whole face with suspiciously little effort and practically tear your whole arm to shreds with a simple pat on the shoulder (that shit's hard, I've tried), why can't they claw their way through a shitty wooden wall? I don't care if you're dead, you can't just grab a chunk of a person OFF of them like they're a Costco birthday cake and eat it (go ahead, try it)!
