This is heavily galvanised wire mesh. The height of the mesh is 90cm (approximately 3ft) and the mesh size is 12.5mm x 25mm (half inch by an inch). The wire diameter is 1mm.
The mesh comes in two different lengths: 6m and 30m
The very strong electro-welded mesh has a multitude of uses apart from cages and aviaries. It can be used for dog-proofing a garden or repairing fencing or for covering or surrounding a pond, protecting tree trunks from animals, making chicken coops or animal enclosures, security screens on windows etc. As well as being much stronger than other mesh options (such as chicken wire), it is more rigid and just looks much nicer.
