Wire Mesh – choosing the right size for the job

Gauge (g) - gauge is a measure of the thickness of the actual wire strand used to make the mesh. The lower the gauge number, the thicker the wire will be. For example, 16g mesh is thicker (and stronger) than 19g mesh.

Common wire gauges used for mesh and their diameters in inches and millimetres are given below:
·    12g - 0.104″, 2.6416 mm
·    14g – 0.080″, 2.0320 mm
·    16g – 0.064″, 1.6256 mm
·    19g – 0.040″, 1.0160 mm
·    22g – 0.028″, 0.7112 mm
Mesh size - mesh size is usually given in inches and refers to the size of the ‘holes’ in the mesh. For instance, wire listed as 1″ x 1/2″ will be a mesh comprising 1 inch x 1/2 inch squares.
Common mesh sizes and their popular uses are given below:
·    1/4″ x 1/4″ - usually supplied in 22g. Ideal for keeping rodents, making mouse traps or keeping vermin out. Also popular for making wild bird feeders and nut holders.
·    1/2″ x 1/2″ – usually supplied in 19g. Ideal for cages and runs for rabbits, guinea pigs, chipmunks, cage birds etc.
·    1″ x 1/2″ - usually supplied in 19g and 16g. One of the most popular mesh sizes. Very common to use for bird aviaries/flights, rabbit/guinea pig hutches and runs and fencing.
·    3/4″ x 3/4″ - usually supplied in 19g and 16g. Useful for fencing. 16g is ideal for chinchillas as it is robust enough to withstand climbing! This size is also a good choice for parrot enclosures.
·    1″ x 1″ - usually supplied in 19g and 16g. Another popular choice for fencing. 16g is useful for cat enclosures. 14g is a good choice for projects where extra strength is required such as parrot enclosures and dog pens.
·    2″ x 2″ - usually supplied in 14g and 16g. Very popular for dogs and also useful for horses as it is more robust (won’t wrap around the feet if trampled) than 19g mesh often used.
Height – The height of the roll, given in inches. Mesh is usually supplied in 36″ and 48″ high rolls as standard.
Length – The actual length of mesh on the roll, given in metres. Most commonly 30 m rolls are supplied as standard.
Galvanisation - wire mesh is treated by galvanising. This is a process whereby the wire is hot-dipped into molten zinc, which oxidises on cooling to leave a zinc oxide coating on the wire. This coating protects the wire to help resist corrosion and form a weatherproof barrier. Galvanising can be performed either before (whilst the wire is still a strand) or after welding (on the completed mesh). Galvanising post-weld is more expensive in manufacturing wire mesh as it requires larger baths for the hot-dipping and the mesh is more difficult to handle compared to single strands.
Mesh that has been galvanised after welding (although more expensive to manufacture) is stronger, as the coating acts to reinforce the mesh at the weld points.
