Our galvanized wire mesh is "galvanized after weld" (GAW) which means the steel wire is welded into a mesh, fully welded, then dipped into a molten galvainizing bath. The galvanizing process makes the wire rust-resistant as well as durable, as the galvanizing helps to protect and seal the welded joints. GAW wire mesh is an affordable choice in wire and is significantly longer-lasting than GBW (galvanized before weld) wire.
