Galvanising is not a metal or alloy; it is a process of applying a protective zinc coating to steel to prevent rusting. However, in the wire mesh industry, it is often considered a separate category due to its widespread use in all types of applications. Some of the more popular uses and applications of galvanised wire mesh are listed below.
Galvanised Welded Mesh
Fencing, cages and enclosures
Farm, garden and agricultural uses
Window and security guards
Archaeological uses
Construction work
Infill panels
High security applications
Landscaping and gabions
Wall stone retention
Greenhouse utilisation
Particle separation
General industrial use
The manufacture of post-galvanised wire mesh has advantages over the manufacture of pre-galvanised wire mesh. The reason for this is the way in which it is manufactured. Post-galvanised wire mesh can be either welded or woven. After welding or weaving, the wire is immersed in a molten zinc bath. The zinc bonds to the surface of the wire, sealing it completely and preventing rust and corrosion.
Galvanised Welded Mesh
When galvanising prior to making welded wire mesh, the zinc coating at the welded joints can be damaged. It can be burnt off, leaving the wire unprotected. And these crossed areas tend to hold more moisture than single strands of wire.
Woven mesh, especially lightweight mesh like hexagonal mesh, also has its weaknesses. The twisted areas of the mesh tend to retain moisture, causing them to rust. Immersed in a zinc bath, these wire meshes are durable even in corrosive environments.
One of the main advantages of galvanised wire mesh (especially welded galvanised gauges) is that it tends to be available in a variety of opening sizes and diameters. For example, mesh sizes such as 4" x 4", 2" x 2", 1" x 1" and ½" x ½" can often be easily obtained from stock in a number of commonly requested diameters of wire.
Due to its attractive price point and corrosion resistance, galvanised wire mesh is very popular among industrial users of wire mesh. Typically, galvanised wire mesh is specified for applications where larger opening sizes are required. Bear in mind that galvanising relatively fine meshes after weaving may clog openings and make them unusable for a wide range of applications. It is for this reason that 10 x 10 mesh and finer are often manufactured as a pre-galvanised woven product.

Lasts a long time
Withstands rough use
Has an extra thick zinc coating
Thoroughly protects joints from rust and corrosion
More useful in areas where previously galvanised wire mesh would corrode
