Chain Link Fence Specifications: Sizes, Heights, Wire Gauges, and Diamond Mesh Options for Australian Projects

The most common commercial chain link fence height in Australia is 1800mm (1.8m) for general perimeter fencing. Industrial sites typically specify 2100mm to 2400mm. Residential and light commercial applications often use 1200mm to 1500mm. Standard heights run from 900mm up to 3600mm+; custom heights are available on request.

For most commercial applications, 2.5mm core wire with 50mm diamond mesh is the standard baseline. For industrial perimeters and AS 1725 Class 3, use 3.15mm wire. For Class 4 and high-security applications, 4.0mm wire is the appropriate specification. If you're unsure, specify one gauge heavier than you think you need.

50mm refers to the aperture of each diamond-shaped opening in the woven wire mesh, measured from centre-to-centre of opposite wire intersections. It is the standard aperture for commercial and industrial chainwire in Australia and the reference dimension in AS 1725. Smaller apertures (40mm) are used for tighter security; larger apertures (60mm, 75mm) for rural and light-duty applications.

Yes. In Australia, chain link fencing, chainwire fencing, and cyclone fencing all refer to the same product: a woven steel wire mesh fence with interlocking diagonal wire forming a diamond pattern. The terms are interchangeable. "Cyclone" is an older trade name that remains in common use, particularly in Queensland and Western Australia.

Yes. Chain link is one of the most common fencing types for tennis courts and other sports courts in Australia. Sports court fencing typically uses 2.5mm to 3.15mm wire with 50mm or 40mm diamond mesh, at heights of 3.0m to 4.0m, often with a PVC or fuse-bonded finish in green or black. Wind screens are frequently attached to the upper portion of the fence.

Properly specified galvanised chainwire with a coating mass of 275 g/m2 or above will typically last 25 to 40 years in non-coastal, non-industrial environments. Fuse-bonded or PVC-coated variants can extend service life further, particularly in coastal or humid conditions. Regular inspections and prompt repair of damaged sections prevent localised corrosion from spreading.

Fuse-bonded chainwire applies a polymer coating to each wire before weaving, giving full and even coverage including at wire crossings. PVC-coated chainwire has a thicker extruded PVC sleeve around the wire, available in multiple colours. Both provide corrosion resistance beyond bare galvanised wire. Fuse bonded tends to be preferred for cleaner appearance in commercial settings; PVC coated for colour-specific landscape and park applications.

For standard commercial chainwire at 1800mm to 2100mm height, 48.3mm OD (nominal 40NB) steel posts at 3.0m centres are the typical specification. Corner, end, and gate posts use 60.3mm OD or larger. Posts are set in concrete at a minimum depth of 600mm for 1800mm fence height, increasing with fence height and wind exposure category. All posts should be hot-dip galvanised for outdoor applications.
