Hmm... Where does Cang Du state that his skin actually turns into iron? If you're referring to the discoloration of his skin in ch.559, then let me point out that the Reishi sent through the blood stream, when using Blut Vene, causes such a reaction. It is evident when Ichigo utilizes Blut Vene, in his battle against Yhwach, at the end of ch.513.
