At its core, welded wire fencing is composed of intersecting wires that are welded together at each junction, creating a strong, grid-like structure. The term 100% galvanized refers to the process in which the wire is coated with zinc to prevent rust and corrosion. This galvanization makes the wire exceptionally durable and suitable for outdoor use. The welded construction provides added strength compared to other types of fencing, such as chain link or woven wire.
