Composite Walls adds high durability walls that are resistant to explosions and fire.
Each wall costs 15 steel, 10 plasteel, and 25 metal of your choice.
Requires fabrication research as a prerequisite to research this, and a minimum of 5 construction skill in order to build.
They use the same graphics as base walls so they integrate seamlessly with non-composite versions, and can be painted.
