AA metal pillar.
Metal pillars are a metal building part, crafted from Low Quality Metal. They must be placed on a Metal Foundation, and other metal building parts such as Metal Wall, Metal Doorway and Metal Ceilings can only be placed between metal pillars, making them necessary for a metal building. (Metal Doors are not included in this and can be placed in a Wood Doorway or Wood Shelter) Like Wood Pillars, metal pillars cannot be manually damaged or destroyed by any means and can only be harmed by Decay.
