Are you looking for galvanized welded wire fence?
Do you know you have a choice?
There are two types of galvanized welded wire fencing materials: GBW (Galvanized Before Weld) and GAW (Galvanized After Weld). Visually they appear very similar. But taking a closer look, you can see the difference. And after they have been installed, the difference becomes more remarkable with the passage of time. Which one is a better value, longer lasting, more readily available?
GBW
As it's name implies, Galvanized Before Weld fencing material is made as follows: Galvanized wire is fed into the welder. At the weld point where the wires cross, the zinc is burned away during the welding process. Sometimes you can actually see the burn (as in the picture above). This is the most obvious way to differentiate between GBW and GAW wire mesh. Look for the burn. Of course when this happens, the wire is left unprotected from rust and corrosion. And this is the spot in the wire mesh that collects water when it gets wet. The water and any corrosive entities it contains will hang out in the intersection, slowly eating away the steel.
GBW welded wire mesh is a utilitarian, readily available generic product. It comes in a wide variety of different gauges, mesh sizes and roll sizes. This type of mesh and fencing material has many different uses. If you want an inexpensive mesh with a moderate lifetime expectancy, GBW is the ideal choice.
GAW
Galvanized After Weld wire mesh is a superior, higher quality, longer lasting product. After being welded, the mesh is drawn through a bath of molten zinc. The wire intersections are thoroughly sealed and protected from exposure to environmental sources of corrosion and rust. As seen in the above picture, corrosive elements have no access to the wire or weld points. The heavy layer of zinc will protect the underlying wire for years, even when exposed to harmful chemicals and other environmental stressors.
GAW fencing materials are far superior to GBW. And they will last years longer than GBW. This is why they are the perfect choice to consider when you want a galvanized welded wire fence. Your initial investment cost is higher. But that is more than offset by the extended lifetime of the wire. Not only will you get years of use from your fence. But also you will save on the expenses of repairs and replacement. Why go through those frustrations and hassles?
GAW meshes are the best choice for animal cages as well. The heavy galvanizing will stand up to corrosion from feces and urine. The need for cage replacement will be diminished greatly. Higher initial cost of a quality product will ultimately save you money.
In general, GAW products are harder to find. There are few retail stores that sell them, partly due to their greater expense. But the demand for these higher quality welded wire fencing materials is not very strong. That's because most people do not know about Galvanized After Weld and that there is a huge difference.
When people say the wire is galvanized, they are usually thinking about the generic GBW products. GAW never comes to mind, even though they might prefer to buy a higher quality product. The assumption is made that since the wire is galvanized, it will last for years. However, if they only knew, they could purchase something far better that would satisfy then for a lot longer.
So what do you think? Do you have any projects where using a higher quality product makes sense to you?
Is quality more important to you than price?
