While fencing spires act as “posts” in wrought iron fences, posts are the square pieces of fencing that are either bolted to a surface or buried in concrete in the ground. These elements are crucial to the structure and durability of wrought iron fencing. A sturdy, well-installed fence will be able to stand up to season after season of inclement weather. Brackets, on the other hand, are unique to wrought iron fences. These elements hold fencing components to the posts. Brackets typically slide over rails and are set against posts before being screwed into place.
