Notes
The Flat Steel Door is a high‑tier (tier 5) placed building component used to enclose rooms in advanced construction. Because rooms require real doors (Update 13), installing a tier‑5 door contributes to a higher room‑value score, which improves the housing‑based XP bonus for residents. Use it to upgrade a settlement’s core buildings—paired with other tier‑5 materials and furnishings—to maximize skill‑point gain for the community.
