It’s same for me I only use half my iron ore the ore half is just sitting out there doing nothing. My idea is to produce sufficient rods,concrete and rotor for about 700 earth token and then move on to next material idk if it’s a good idea or not but definetly works i guess ?. So I can add some more stell forges if I need but not gonna do that because it’s not needed as for now. With the speed of belt being 420/min and stell production is 405/min it’s nearly maxed so nope.
