Four types of wire mesh fencing materials
When you are choosing a wire fence, one of the most important thing to know is the material of the wire. There are four types of wire mesh fencing materials, which hope can help you.
1. GAW
Galvanized wire after fencing materials are galvanized after the welding or weaving process. The mesh is drawn through a bath of molten zinc which thoroughly seals the wire, including the welded and woven areas. These products are heavily protected from rust and corrosion and have an extended lifetime that far exceeds the lifetime of the same products with GBW finish. GAW items are initially more expensive. However when you consider the extra material and labor cost of replacement, the higher initial cost of GAW also should be considered. The GAW hex netting meshes are often used in salt water applications and in building game bird pens - areas where long life is sought and appreciated.
2. VC
Vinyl coated fencing materials are coated with either polyester or PVC after the welding or weaving process. It's also called iron wire with poder coated. The most common colors are black and green. As with GAW products, the vinyl coating thoroughly coats the entire mesh, sealing it against rust and corrosion. The vinyl is easily cut and can then be peeled off the wire with your fingers. The higher quality grades have vinyl coating that is tightly bonded to the wire and resists scraping, even with a knife. Higher intiial cost can save you money over the life of the mesh. There are welded meshes used in lobster traps, safety mesh in railings, animal cages and other unique applications. Woven hex mesh is used in such things as bird pens and deer fence.
3. GBW
Galvanized wire fences can be either welded or woven. Galvanized wire is used to manufacture the mesh.
Welded products - the zinc coating is burnt off during the welding process. In wet weather, moisture tends to collect at the joint, hastening the process. It is true that zinc can "flow" from the areas adjacent to the burnt intersection, and the weld spot never regains its full protection. These are the types you see in your local building supply store and garden center. It is important to keep in mind the fact that these items have a limited lifetime. Welded GBW fencing materials are relatively inexpensive and utilitarian.
Woven products - these do not have any welded areas and therefore do not have the same vulnerability. The heavier fences have an extended lifetime, especially those with Class 3 galvanizing.
4. SS and other alloys
Stainless steel fencing materials are the most specialized type available. They have the advantage of being resistant to rust, corrosion and other environmental stressors. Stainless steel welded wire meshes have often been used as fences in coastal areas. They are quite expensive and can be difficult to impossible to obtain at retail stores. Their appearance is more beautiful. These items have a long life. Other alloys such as copper are also suitable in many field of fence.
