Steel wires are woven into diamond shapes before galvanizing process. After forming into a flat chain link mesh fabric, it will go through be placed in molten zinc bath. During zinc coating, the wire mesh fabric is covered all over. The zinc coating increases greatly resistance to rust. Anti-corrosion performance is quite strong. GAW fencing will last many years on end. For businesses who aim at commercial and public projects, with a raw metal finish, GAW is a perfect choice.
GBW, also called “pre-galv weaving“, is more economical than GAW. Galvanization is done before wires are proceed in the chain link weaver. It also provides a good corrosion resistance. Generally, GBW is preferred for projects with tight budgets or for residential and commercial applications involving plastic coating.
