Chainwire is the fence most people picture when they think of a security boundary: galvanised steel wire woven into an open diamond mesh, stretched between posts and rails. It is strong, long-lasting and priced to cover big perimeters, which is why it turns up everywhere from schools and sports grounds to factories, building sites and rail corridors. We have been supplying and installing it across Newcastle and the Hunter since 2004.
Cyclone fencing and chain mesh, the same fence by older names
If you grew up calling it cyclone fencing or chain mesh fencing, you are describing exactly this product. "Cyclone" comes from the old brand name that became a household word, and "chain mesh" is the same open-weave wire under a different label. When you ask us for cyclone or chain mesh fencing, you will get galvanised chainwire, built the same careful way.
Why chainwire holds up
The open mesh keeps sight lines clear, which matters when you need to watch a yard, a crowd or livestock through the fence rather than around it. It is quick to install over long runs, it takes barbed wire or a spear top when you need extra deterrent, and galvanised wire shrugs off weather for years with almost no upkeep. For the metres of coverage you get, little else competes on value.
Heights, rails and strength
Australian-made chainwire comes in standard heights from 0.6 m up to 3.6 m, rising in 0.3 m steps, with 1.8 m the usual choice for a security boundary. A basic fence uses a three-cable design, plain 3.15 mm wire twisted either side of each post for tension. Adding top and bottom rails lifts the strength and life of the fence considerably, and heavier gauges or reinforced links step it up again where the site demands it. Fence lines do not have to run in straight grids either, they can curve with a track or step down a slope.
Colours
Most people know the bright silver of galvanised wire, but chainwire also comes in black and green. Black reads as clean and almost see-through against a background, while green blends into gardens and bushland. See our black chainwire fencing if you want the fence to disappear into the view.
Where it goes
Schools, parks and reserves, transport corridors, sporting grounds, factories, building sites and rural blocks all run on chainwire. For higher-security jobs it pairs with barbed wire on top or a tighter weldmesh panel where a small aperture is needed.
If you are weighing up a boundary and are not sure on height or gauge, tell us what you need to keep in or out and we will spec it from there.
