Bar fence
Bar fence or bar fencing is a type of fully welded fence panel that is used in some countries.
It is usually manufactured by the fence company themselves, and is usually made on in a factory using a variety of jigs to make panels that match the gradient they will be installed on.
Bar fences are usually made from various kinds of tubing, and are usually hot dip galvanized after manufacturing. They might also be painted or powder coated after manufacturing.
Commercially available ornamental fence is very similar to bar fence, but it is often made from thinner metal, and it's usually not custom made for a particular site.
