The calculator reads zero scrap for research here, and that is only half the story. The industrial door has no blueprint of its own because it is a skin of the garage door: you learn that blueprint at a Level 2 bench, craft the plain door and choose this look if your account has it.
So the bill is the garage door's to the last line, and before Level 3 the two gears still set the pace. Nothing in the rows changes with the paint, and nobody has shown it soaks up more explosives. The recycler hands back the same parts.
It is the same trade the industrial torch makes: a look, nothing more. Without the skin, the plain door does the same job for the same price.
