Iron Frames
Iron Frames are your basic building blocks. Iron walls can be used but they don't allow structures to be placed. Iron frames do not have to have iron sheets added on them to place structures. You can use the frame itself. The frame without sheets allows you to walk through it and place cables and pipes inside. Which you can seal up after to pass connections through rooms.
