Welded Wire Mesh & Fence - Galvanized Before Weld (GBW)

Welded wire mesh and fence that is Galvanized Before Weld (GBW) is economical and ideal for many uses. The wires used in the manufacturing process are galvanized before they are welded into a variety of mesh sizes. Different gauge wires are used. The gauge and mesh sizes are determined by the final use of the product. Smaller meshes made with lighter gauge wires are ideal for making cages for small animals. The heavier gauges and meshes with larger openings make good fences.

GBW products have one disadvantage. During the welding process, 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.

In deciding which kind of galvanized welded wire fencing mesh to use, take the following into consideration:

  • How long do you want the fence or mesh to last? 
  • What factors determine the mesh size that you want to use?
  • Are there environmental factors that could potentially shorten the lifetime of the wire?
  • Does your project require a lot of labor that will need to be repeated when the wires rust through and need replacement?
  • Will the appearance of rusting wires be objectionable?

There are alternatives to Galvanized Before Welded wire mesh and fencing. Both Galvanized After Weld (GAW)Vinyl Coated (VC) and Stainless Steel (SS) fences and meshes guarantee longer life. And vinyl coated material offers a more attractive finish.
