This report was aimed to give a metatechnical consideration on the significance of iron technology and its industry for the human life. First the philosophical concept of the technological cohesion was tried to be explained from the engineering standpoint. And the various important characteristics of our modern technology which has been environmentalized and their serious effects on the human and the society were made clear. Then it was strongly claimed to establish the "eco-ethica" as our new norm of act in the modern age and the metatechnica as a new discipline beyond all kinds of speciality.
In the latter part of this research were considered the position of material in the whole technology system and its importance as the first step for the human to introduce and change "nature" citing the examples of iron material. And finally the difficult situation of the iron industry at the age of technological cohesion, ie., the trilemma of iron was clearly suggested with some measures to be taken.
