Question about wood wall and metal door destruction

Hi all, I searched the forums but haven’t found much on this.

But are wooden walls and metal doors destructible using hatchet/pick axe? If so, do you know how many hits it will take to take them out? If possible, perhaps somebody could go above and beyond and post up some info about how many it takes to destroy all kinds of stuff in the world like metal walls and such.

Thanks!

Wooden walls and metal doors are indestructible to pickaxe and hatchets, the only hatchet destroyable things are wooden shelters, wooden doors and things like wooden barricades and storage boxes.
