Mesh Open 100mm*50mm GAW Wire Mesh Window Guard ASTM A740

Galvanized after wire mesh, also called hardware cloth, is manufactured by taking (usually) low carbon steel wire mesh and galvanizing (zinc coating) it following weaving or welding. This process differs from the galv before wire mesh production process where strands of low carbon steel wire are first galvanized and then woven or welded together into mesh. While galv after wire cloth is slightly more expensive than galv before, it offers better corrosion resistance, especially when welded material is used in outdoor settings. This is because the protective zinc coating is burnt off when galv before material is welded together, leaving its weld joints exposed and unprotected. When woven together, galv before offers similar levels of corrosion protection as galv after.

GAW (Galvanized After Welding) Welded Mesh

In this process, the mesh is hot-dipped galvanized after the wire is welded, coating all the weld intersections. GAW welded wire mesh performs well in damp environments and is used in applications such as ventilation screens, animal enclosures, and light duty industrial applications.

GBW (Galvanized Before Welding) Welded Mesh

In this process, the wire is coated prior to welding, leaving the welds uncoated. While GBW provides some protection against damp conditions, it is more prone to rust than GAW mesh. It is primarily used for indoor applications such as security screens and guards for machinery.

Welded Wire Mesh

Qijie Company is the leading industrial welded wire mesh supplier and manufacturer offering a full line of welded wire mesh products for a wide range of applications. Welded wire mesh is generally constructed in rolls or flat panels depending on the wire and opening size. Qijie’s welded wire mesh varieties include square and rectangular openings. Custom wire openings are available upon request. The intersections of the wire mesh are typically resistance-welded according to the alloy requirement. Weld set down (thickness of the welded intersection) and weld strength are determined by weld time, weld pressure, and weld temperature.
