This wire mesh is the most economical. However it has a limited lifetime. During the welding process, single strands of galvanized wire pass through the welder. The rust-preventing galvanizing is burned off at the weld points where the wires intersect. Water will collect at these weld points where the galvanizing is compromised, causing rust. GBW wire is a general purpose welded wire mesh which is ideal to use for small animal cages, such as rabbits. It can aslo be used as a low-cost wire fence, dog kennels and a variety of other uses.
