Column

Columns are passable structures primarily used to hold up roofs

Columns are capable of supporting roofing up to 6 tiles away in all directions. If a wall is destroyed or deconstructed, any unsupported roofing will instantly fall and injure any pawn below it, possibly fatally.

In this way they are similiar to walls. In contrast to walls, they provide significantly less cover, can be shot over/through, don't block LoS or Line of Effect, and can be walked though without even slowing a pawn down. They are also somewhat beautiful, have less HP and require significantly more resources than a wall.

Columns are built and repaired by colonists assigned to Construct. Columns construction may sometimes fail and waste the materials, more often with lower construction skill.

They are required for Nobles of Knight or above.

Acquisition

Columns require 20 Stuff (Metallic/Woody/Stony, 200 for SMVs) and take 750 ticks (12.5 secs) to build.

Analysis

Columns are useful for stockpiles as they do not block the radius of Orbital trade beacons, unlike walls. On the other hand, they are 4 times more expensive.
