What is Double Dipped Wire?
(or galvanized after wire)

Coating iron or steel with a thin layer of zinc is called galvanizing. Spraying, dipping or electro-galvanizing are all methods of applying this coating. Keeping corrosion and rust at a minimum is the main reason for galvanizing.

The first step in producing cage wire is to size or gauge strands of steel. It is then galvanized and welded into certain patterns. x , x1, 1x1 and 1x2 are popular sizes used by animal enthusiasts. The wire sizes are usually 14 or 16 gauge. At all points where two wires cross, high temperature welding can cause charring. It is easy to notice the darkened areas with close inspection of the wires. These connections can accumulate dirt and foreign particles. The welding and connections may cause quicker deterioration in these areas. When galvanized, welded wire is sent back through the zinc vats, it becomes double-dipped wire. All welded connections are filled and recoated with zinc to insure the corrosion process will be inhibited for a longer time. The galvanized-after wire is shinier and the tensile is a little less. Tensile means the tension of the wire. 

Of course, this extra dipping process is going to make the cost of the wire go up. Making it last so much longer before rusting makes it a bargain. Whenever replacement or repairs are necessary, a lot of time and effort is expended. The same amount of time that it takes to build a cage is usually spent on repairing a cage. The corrosion or rust that can accumulate on regular coated wire, may cause health problems in the animal and cause the fur to be stained.

When building a cage with GAW (galvanized after weld wire), its important to use long lasting stainless steel j-clips or c-rings. If the clips start corroding at an early rate, it can cause a premature deterioration of the wire cage. Once the corrosion process has begun, it is difficult to control.

When cleaning a wire cage by using a torch, be careful to not apply too much heat to any area for very long. Apply just enough to singe hay and fur, not to harm the zinc coating. Any galvanized wire can start corroding quickly if too much heat is applied to the surface.

Rabbit urine has a very high acidity. Its almost as strong as the most toxic acids. Acid is zincs biggest enemy. Cleaning the cages at least three or four times a year, will prolong the life of the cage. Using a wire brush and water will clean most problem areas. Cage floors are the most susceptible places for acid attacks.

Good luck,
