How Many Propane bombs for a Sheet Metal Wall?
13 propane bombs
— or 9 from the soft side
13 propane bombs destroys a Sheet Metal Wall (1,000 HP) from the hard side. That's 11,700 sulfur once you count the gunpowder, and about 1m 18s to place.
Timed Explosive Charge is cheaper for this.
4× Timed Explosive Charge costs 8,800 sulfur against 11,700 for 13 propane bombs — a difference of 2,900 sulfur per sheet metal wall. If you've already got the propane bombs, use them; if you're farming from scratch, don't.
What 13 propane bombs costs
These are full craft costs — the sulfur figure includes everything that goes into the gunpowder, which is why it's bigger than the recipe on the item page suggests. Sulfur is the number that actually matters, because it's the thing you farm.

Frequently Asked Questions
How many propane bombs for a Sheet Metal Wall in Rust?expand_more
13 propane bombs to destroy a Sheet Metal Wall from the hard side — that's 11,700 sulfur once you count the full gunpowder chain. From the soft side (inside face) it's 9, because the interior takes more damage per hit.
What's the soft side of a Sheet Metal Wall?expand_more
The soft side is the interior-facing face — the side you see from inside the base. It takes roughly 34% less to break, so 9 propane bombs instead of 13. If you can get an angle on the inside face through a doorway or window, take it. On a wall, the soft side is the one without the visible seams.
Are propane bombs the cheapest way to raid a Sheet Metal Wall?expand_more
No. Timed Explosive Charge is cheaper on sulfur for this target — 4× costs 8,800 sulfur versus 11,700 for 13 propane bombs. That said, cheapest isn't always right: propane bombs may be faster to place or already in your base, and sulfur you've already farmed is a sunk cost.
How much sulfur is 13 propane bombs?expand_more
11,700 sulfur, plus 17,550 charcoal. That's the full craft cost including the gunpowder each propane bomb needs, not just the final recipe.
How long does it take to raid a Sheet Metal Wall with propane bombs?expand_more
About 1m 18s of placement time for 13 — that's the deploy time, not the farming. The farming is the real cost, and it's why people check this number before they commit.
Amounts come from the same sourced raid chart as our raid calculator and every /raid/ page, so they can't disagree with each other — verified for the July 2026 wipe. Deployables and external walls are approximate; always test on your own server build. Sulfur includes the full gunpowder chain.
