Updated 4th July 2018. A list of how much damage each weapon inflicts against a sheet metal door. Sheet metal doors cos 150 metal fragments and have 250 hitpoints.
Similarly, you may ask, how many satchels do I need for a metal door?
Both the sheet metal door and sheet metal double door require 4 satchel charges to be destroyed. Both the armoured door and armoured double door require 12 satchel charges to be destroyed.
Furthermore, how many grenades does it take to destroy a metal door in Rust? Don't know about metal doors, but supposedly 15-20 will take out a wood wall. Throwing them to rest against something without them bouncing off is the real trick. Grenades do only 8-20 damage per hit (20 being a perfect hit) to structures. You'll average around 9-12 damage per grenade.
Subsequently, one may also ask, how many surveys are needed for a sheet metal door?
It takes about 50 survey charges to break a sheet metal door.
How many Beancans do I need for a wooden door?
6 for a wood door and 18 for a sheet door.
