Chain link fencing is interwoven metal wire creating a “diamond” pattern. The mesh is secured to the frame using steel components. The common mesh size for chain link is 2″ x 2″ but many other sizes are available.
Welded wire fencing is constructed of criss-crossed metal wire creating a rectangular pattern. The mesh is welded at every intersection, and directly to the frame. Common mesh sizes for welded wire are are 2″ x 4″ and 2″ x 6″ but as with chain link, other variations are also available. Welded wire offers the added benefit of being very difficult to climb, which may be a consideration for your job site.
