Galvanized chain wire fencing, often called chain link fencing, is manufactured from steel wire that is woven into a uniform diamond pattern. The key to its durability lies in the galvanization process. This involves coating the steel wire in a protective layer of zinc, which acts as a powerful barrier against rust and corrosion. This is a critical feature in Australia's diverse climate, from the salty coastal air of Sydney to the intense sun and rain in other regions.
