GAW and GBW Welded Wire Panels

GAW and GBW are used for referring two processing technology of Galvanized Welded Wire Mesh products. GAW is simplified terms of Galvanized After Weld(Learn More About GAW Processing) , that is the welded panels are made with pre-galvanized wire then welded into square structures. GBW Galvanized Before Weld means the opposite processing, that is welded with mild steel wire with no zinc coating and the galvanizing is done after the welded wire structure is formed. The two processing terms apply to both electro galvanized and hot dipped thick galvanized welded wires. GBW welded wire panels cost less compared with GAW but it has one disadvantage. During the welding process of the GBW, the galvanizing at the weld spots, where the wires intersect, is burned away. This leaves places in the mesh that have lost the galvanizing protection against rust and corrosion. The weld locations are critical spots that tend to hold moisture longer than the individual wires. This can promote a more rapid decay, as rust eats into the unprotected steel. In interior locations, where the mesh or fence is not exposed to the elements, this is not as much of a problem. Heavier gauge wire will last longer due to the fact that it will take longer for rust to eat through the wire.

Metech Welded wire panel that is Galvanized After Weld (GAW) is stronger and durable. These products are made by dipping previously welded steel mesh sheet into a bath of molten zinc. The entire mesh panels, including the welded spots, are thoroughly coated with zinc plating against rust and corrosion. Metech GAW panels will last years longer compared with GBW and can be used in various conditions.

Advantages of Welded Wire Panels:
1. High intensity anti-high temperature.
2. Better strength and strong integration
3. Flat & even surface and strong structure
4. Anti-rust property
5. Not easy to loosen even be cut into parts or exerted force on the parts
6. A long service life and the service life can reach to several decades

Assortments available:
1. Hot-dipped galvanized after welding (GAW);
2. Hot-dipped galvanized before welding (GBW);
3. Electro galvanized after welding (GAW);
4. Electro galvanized before welding (GBW);

Mild Steel Galvanized Welded Wire Panels GAW and GBW is traditionally utilized as guards in buildings and factories, as animal enclosure and fence panels in agriculture; it is also used in horticulture industry as tree guards fences, plant protection as well as other usages. Also used as temporary fence panels or crowd control barriers. Heavy type GBW is popularly used as reinforcing steel mesh in concrete buildings.
