The iron platebody is the second weakest platebody in free-to-play, being stronger than the bronze platebody. Level 33 Smithing and 5 iron bars are required to smith an Iron platebody by using an iron bar on an anvil with a hammer in your inventory or tool belt, granting 125 Smithing experience. For players training Ranged or Magic, an iron platebody is not a good choice due to its crippling negative bonus in those skills. Like all iron equipment, this requires a defence level of 10.
It is also the tertiary ingredient used in making iron titan pouches. It is an item used in clue scrolls.
Since iron items are over-produced, the best way to get rid of them is by selling them to the stores. If the stock number in a store is less than 10, it is worth selling, as price is higher than low alching using Explorer's ring.
With a Pack Yak, it is possible to achieve rates of 95k to 100k Smithing experience per hour. It is also worth noting that the Scroll of efficiency, bought as a reward from Dungeoneering can increase the items made per trip due to its bar saving effect.
