Welded fence fabric is a form of mesh wire in which the vertical and horizontal wires are joined by a spot weld. This differs from woven wire in which the junctions are joined by a wrap of the vertical wire around the horizontal wire. Curvy welded fencing is sturdier than other mesh fencing, which makes it easier to install. Curvy welded fencing can be installed on the top of the ground or can be partially buried if you are trying to keep out rabbits and other burrowing animals. It can be installed with wooden posts or with metal T-posts, which are placed between 6 and 12 feet apart, depending on the application.
