Galvanised Mesh – Discover The Benefits of This Versatile Material

galvanised mesh

Galvanised mesh is usually supplied in stock dimensions and comes in numerous shapes and sizes. It’s a versatile material that can be used in many different ways from machine guards and protective cages to fencing and anti-burglary screens.

While the construction and building industries are the largest users of galvanised mesh it can, however, be used for many other applications, including:

  • Rural fencing
  • Wall retention
  • Landscaping
  • Outdoor fencing
  • Safety guards
  • Agricultural barriers/structures
  • Concrete reinforcement in foundations
  • Infill panels

What is galvanising?

Galvanising is the name given to the process of applying a coat of zinc to protect the steel from corrosion. The process can be carried out before or after the wire mesh has been manufactured whether it’s for woven mesh or welded mesh types.

‘Galvanised before’ refers to the process of galvanising the wires before the mesh is welded or woven. Typically, this is the cheapest option (depending on the opening size of the mesh) and especially when custom manufacturing is needed.

As the name suggests ‘galvanised after’ takes place after manufacture. The mesh is normally manufactured in plain or carbon steel and dipped in a galvanising tank to meet the criteria of ‘galvanised after’ welded or woven mesh. Depending on its availability, this latter option usually costs more but provides greater resistance to corrosion. Typically, this reduced risk of corrosion tends to occur at the joint of the ‘galvanised after’ specification of the welded mesh.

Galvanised mesh – What are the benefits?

One of the prime benefits of gal mesh is that there is a wider choice of diameter opening sizes and wires. For instance, most suppliers of galvanised mesh tend to keep in stock mesh with openings of ½ x ½, 1 x 1, 2 x 2, and 4 x4 with differing sizes of wire diameter.

Because of its resistance to corrosion and its fairly inexpensive price tag, it’s a very popular choice for industrial use. That said, it’s worth bearing in mind that the process of galvanising a relatively fine mesh is likely to clog up the openings, so it’s of little use for several applications. This is why, for mesh that is 10 x 10 or finer, it’s usually manufactured as a ‘before galvanised’ form of woven or welded mesh.
