How Many Satchels for a Sheet Metal Double Door?

Satchel Charge

4 satchels

— or 3 from the soft side

4 satchels destroys a Sheet Metal Double Door (250 HP) from the hard side. That's 1,920 sulfur once you count the gunpowder, and about 32s to place.

Explosive 5.56 Ammo is cheaper for this.

63× Explosive 5.56 Ammo costs 1,575 sulfur against 1,920 for 4 satchels — a difference of 345 sulfur per sheet metal double door. If you've already got the satchels, use them; if you're farming from scratch, don't.

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 satchels for a Sheet Metal Double Door in Rust?expand_more

4 satchels to destroy a Sheet Metal Double Door from the hard side — that's 1,920 sulfur once you count the full gunpowder chain. From the soft side (inside face) it's 3, because the interior takes more damage per hit.

What's the soft side of a Sheet Metal Double Door?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 3 satchels instead of 4. 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 satchels the cheapest way to raid a Sheet Metal Double Door?expand_more

No. Explosive 5.56 Ammo is cheaper on sulfur for this target — 63× costs 1,575 sulfur versus 1,920 for 4 satchels. That said, cheapest isn't always right: satchels may be faster to place or already in your base, and sulfur you've already farmed is a sunk cost.

How much sulfur is 4 satchels?expand_more

1,920 sulfur, plus 2,640 charcoal and 320 metal fragments. That's the full craft cost including the gunpowder each satchel needs, not just the final recipe.

How long does it take to raid a Sheet Metal Double Door with satchels?expand_more

About 32s of placement time for 4 — 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.
