63× Explosive 5.56 Ammo costs 1,575 sulfur against 3,000 for 50 F1 grenades — a difference of 1,425 sulfur per sheet metal door. If you've already got the f1 grenades, 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 F1 grenades for a Sheet Metal Door in Rust?expand_more
50 F1 grenades to destroy a Sheet Metal Door from the hard side — that's 3,000 sulfur once you count the full gunpowder chain. From the soft side (inside face) it's 33, because the interior takes more damage per hit.
What's the soft side of a Sheet Metal 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 33 F1 grenades instead of 50. 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 F1 grenades the cheapest way to raid a Sheet Metal Door?expand_more
No. Explosive 5.56 Ammo is cheaper on sulfur for this target — 63× costs 1,575 sulfur versus 3,000 for 50 F1 grenades. That said, cheapest isn't always right: F1 grenades may be faster to place or already in your base, and sulfur you've already farmed is a sunk cost.
How much sulfur is 50 F1 grenades?expand_more
3,000 sulfur, plus 4,500 charcoal and 1,250 metal fragments. That's the full craft cost including the gunpowder each F1 grenade needs, not just the final recipe.
How long does it take to raid a Sheet Metal Door with F1 grenades?expand_more
About 11m 40s of placement time for 50 — 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.
