Although wrought iron is a very strong material, it can break under pressure. Broken wrought iron fences can be repaired with epoxy weld. If you have a loose fence, avoid kicking it to readjust the loose parts. Instead, drill down next to the loose post and fill the hole with quick drying concrete to set it straight again.
We used the guys over at H&M for a wooden fence around one of our rental properties last summer. Its still standing as strong as when it was first installed. Would highly recommend and will definitely use them for future...
