Anti-climb mesh is a category, not a single product. Here is how the common grades compare and which one is worth paying for on your site.
Anti-climb mesh covers several different products, and they are not interchangeable. At the top sits 358 prison mesh, with 76.2mm x 12.7mm apertures in 4mm wire. Below it, 656 mesh uses a slightly larger 76.2mm x 12.7mm-class opening in lighter wire, while general welded mesh and expanded metal give a much wider opening that slows a climber rather than stopping one. Aperture size, wire diameter and panel rigidity are the three numbers that separate them.
Choosing between them is a question of what you are defending against. Opportunistic trespass on a suburban commercial yard is usually solved by lighter welded mesh at height; deliberate, tooled intrusion at a substation or correctional site needs a full 358 specification. All of these products stay visually transparent, so CCTV and patrol sightlines are preserved through the fence. For survey, specification and installation across Sydney, see our security fencing Sydney hub. For the full product specification and supply options, see our 358 mesh Sydney page, then talk to us about your site.
Every anti climb mesh fence we install is galvanised, available powder coated in your colour, and backed by our licensing and $20M public liability insurance.
The narrow 358 mesh gaps offer no foothold, so the fence cannot be scaled by hand.
Closely spaced 4mm welded wires resist bolt cutters and delay any attempted breach.
See-through mesh keeps cameras and patrols effective while still deterring intruders.

Anti climb mesh fencing is a high-security welded steel fence, most commonly the 358 profile, named for its tight aperture of roughly 76mm by 12.7mm using 4mm wire. The narrow gaps give fingers and toes no purchase, so the fence is extremely difficult to climb, while the closely spaced wires also resist cutting tools. It is the standard perimeter choice for sites across Sydney that need genuine intruder resistance.
Anti climb mesh fencing is used wherever a strong, see-through perimeter is needed. Across Sydney we install it around substations, warehouses, data centres, schools, construction sites, rail corridors and government facilities. Because the mesh keeps clear sightlines while being hard to breach, it suits sites that want both surveillance and security without the closed-in look of solid fencing.
Anti climb mesh fencing in Sydney typically costs a competitive quoted rate supplied and installed, with 358 mesh at the higher end of security options. Height, wire gauge, powder coating, gates and any topping affect the price. We provide a free on-site measure and a fixed written quote so the cost is clear before installation begins.
Anti climb mesh fencing is usually installed between 2.1m and 3.0m depending on the security level required. Residential and school boundaries often sit around 2.1m to 2.4m, while high-security commercial and industrial sites use 2.4m to 3.0m, sometimes with a barbed or razor topping. We help you choose a height that meets your risk profile and any council conditions.
