The Answer
One C4. A single timed explosive charge (2,200 sulfur) destroys a sheet metal door — single or double, they have the same health. That makes the sheet metal door one of the most raid-efficient targets in Rust: cheap to blow, and behind it is often a loot room built on the assumption that the door holds.
Every Way Through, Priced
| Method | Sulfur | Notes |
|---|---|---|
| 1 rocket + 8 explosive ammo | 1,600 | Cheapest by sulfur; needs a rocket launcher plus a gun for the ammo |
| 1 C4 | 2,200 | Instant and simple — the default answer |
| 2 rockets | 2,800 | Most expensive; rockets are for walls and garage doors |
All three prices derive from the unit costs — C4 2,200, rocket 1,400, explosive ammo 25 — so they stay consistent with the full raid cost calculator. Satchel raiding also works on sheet doors but is unreliable and priced between the C4 and the rockets.
Frequently Asked Questions
How many C4 for a sheet metal door?
One C4 (2,200 sulfur) destroys a sheet metal door. Single and double sheet metal doors have the same health, so the answer is the same for both.
What is the cheapest way through a sheet metal door?
1 rocket plus 8 explosive ammo = 1,600 sulfur (1,400 + 8×25) — 600 sulfur cheaper than a C4. Satchel raiding also works but is less reliable. If you already carry C4, one does the job instantly.
How many rockets for a sheet metal door?
2 rockets (2,800 sulfur) — more than a C4's 2,200, which is why rockets are reserved for structures where they shine, like garage doors and walls.
Does the double sheet metal door need more explosives?
No — single and double sheet metal doors have the same health, so both fall to exactly 1 C4 (or the equivalent rockets and ammo mix). The costs in the table above apply to either version.
