The Industrial Door is part of the Industrial Super Bundle that was launched during update R44 in June 2017, and can only be crafted (default crafting key is Q) after buying the Super Bundle in the Store.
Industrial Doors are also included in the Hover Jet Blueprint Pack and the Industrial Pack, but not the recipes.
To craft an Industrial Door, you will need (as of June 2017)
Industrial Doors can be wired up with activation devices like Switches, Sensors, Number Pads or Pressure Plates. Doors will then serve as receivers and can be opened, closed and locked. Their interactivity can be toggled and defined with permission settings.
