Pig iron warehouse
Determines how much pig iron your planet can hold. Once the warehouse is full, your pig iron mine drops to 5% output.

Even without a warehouse a planet holds 100,000 units of each resource. Every level of your Pig iron warehouse doubles the capacity for pig iron. Once the limit is reached, your Pig iron mine keeps running at only 5% of its output – production you paid for goes to waste.
Rule of thumb: the warehouse should hold at least what the mine produces while you're offline – overnight or for a whole day. Also think about your next big construction projects: if their pig iron cost doesn't fit into storage, you'll wait a very long time for the rest.
With pig iron your Blast furnace plays a part: it consumes pig iron constantly, so the warehouse fills more slowly while it's running. Throttle the furnace, on the other hand, and storage fills up fast.
Background
The pig iron warehouse allows for large amounts of pig iron to be stored. The storage capacity of the warehouse changes with each level. If the storage capacity is exceeded, only 5% of the actual target amount will be produced.
