Wrought iron curtain rods are easy to install and last a long time, since they are made of iron. However, you need to keep in mind that the thicker the rod, the heavier it will be, so make sure that the support brackets together with the attachments are strong enough to hold them up (with the weight of the curtain as well), and that the mounting surface is also solid enough to take on the weight. Even so, they are a much better choice than wooden rods, which are subjected to terrible wear and tear every time the curtains are drawn or when the curtain rings glide up and down.
Since there are many designs but not many colors to choose from, make sure that you make the right choice, as the choice you make will be literally hanging around your home for a long time.
