Welded mesh rolls and panels made in the processing of Electro Galvanized Before Weld (GBW) is economical and ideal for industrial and commercial uses. The wires used are galvanized zinc plated 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, tree guards, corn storing circles, while the mesh rolls with heavier gauges and larger openings are mainly used for security fences.
GBW Welded Mesh has 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.
