Not the best recipe (i think its with compacted coal), but less machines, so, best fps :) Its a part one of my factory. (next post with the steel beam/pipe with a... complex surprise ;))

Needed : 4200 coal (1260 import needed) + 2275 iron + 1300 water.

26 refineries (4225 iron ingot) 42 alt solid steel ingot (6300 steel ingot) Power needed : ~8000

Electrical circuits system for : Light Steel production Iron production

Ugly, i know, need decorations and trainstations/heliports. But its the part one, more stuff will be come on it :) If you wait and want the top, come with : 780 beam + 2100 pipes OR 4200 pipes OR 1575 beam ;-)
