Frequently Asked Questions

What is the strongest building material in Rust?
Armored is the strongest building tier in Rust with 2,000 HP on walls. It requires High Quality Metal to upgrade and is very expensive to maintain, so most players use stone or metal for the majority of their base.
How much does it cost to upgrade from stone to metal in Rust?
Upgrading a wall from stone to metal costs 150 Metal Fragments. For a full 1×1 base (4 walls, 1 foundation, 1 ceiling) that is 900 Metal Fragments to upgrade the outer shell to metal.
What is the difference between a wall and a high wall in Rust?
A standard wall is one building block tall (~3m). High walls are external wall objects used for compound perimeters — they are not upgradeable the same way as building blocks and have fixed HP.
How does building upkeep work in Rust?
Building upkeep is charged from your Tool Cupboard (TC) every 24 hours. The cost depends on the tier of each building piece — stone walls cost 6 stone/day each, metal costs 8 metal fragments/day. If your TC runs out, structures decay and eventually demolish.
Which door is the hardest to raid in Rust?
The Armored Door is the hardest door to raid, requiring 2 C4 (4,400 sulfur) or 12 satchel charges (5,760 sulfur). The Garage Door is a popular high-security option that requires 9 satchels or 150 explosive ammo.
