Why Sydney Owners Call Us for Security Fencing

Most security fencing enquiries we take in Sydney come from the same place: a perimeter that can be climbed at the gate even though the fence line is sound. It is worth understanding why that happens here before deciding what to replace it with.

What makes security fencing in Sydney different is the combination of reactive shale clay in the west, sandstone and sand through the coast and north underneath and, on a great many blocks, the need to work around a very wide range of housing eras with different original boundary types.

Ask three contractors for security fencing in Sydney and you may get three different answers. The difference usually comes down to whether anyone has looked at access constraints that vary from a wide western verge to an inner-west rear lane before pricing the job.

Talk to us before you commit to anything. Call 0492 879 796 and we will tell you what your Sydney job actually involves, including the parts nobody enjoys paying for.

What We Specify and Why

The parts you cannot see once the job is finished are the parts worth paying for: footings, drainage, fixings and substructure. That is as true in Sydney as anywhere.

There is no premium in over-specifying something that was never going to fail. We put the money where Sydney conditions actually attack the job, which is generally at ground level and at the fixings.

• 358 mesh takes its name from the imperial aperture, three inches by half an inch by eight gauge, which is why the aperture is quoted as 76.2 by 12.7mm.
• Perimeter height is only one variable; the footing and the gate are where most perimeters are actually defeated.
• Anti-tamper fixings matter only if they are used on the unsecured side, which is where a lot of installations get it wrong.
• A duplex system, galvanising plus powder coat, is specified where the perimeter is both exposed and visible.
• A small aperture defeats climbing and cutting because there is no foothold and no room to get a bolt cutter jaw around a wire.

Choosing a Security Fencing Format

The Sydney Ground Conditions We Design For

Tree cover and root zones matter around Sydney. Roots are worked around rather than cut through, both because the tree matters and because a cut root under a footing is a future problem.

Local housing stock is largely the full spread of Sydney housing, from Victorian terrace to new release estate, and that tells you a lot about what is already in the ground: original service runs, old footings and the occasional buried slab nobody remembered.

One thing specific to this part of the greater Sydney basin is ground conditions that change completely between one side of the basin and the other. It is easy to miss on a first look and expensive to discover once work has started.

What Usually Brings People To Us

Owners in Sydney tend to call us at the point where patching has stopped working. By then the underlying issue is usually cut damage through a wide-aperture chainwire mesh, and a repair only postpones it.

• Gates that have dropped and can be lifted off their track
• A perimeter that can be climbed at the gate even though the fence line is sound
• A boundary that no longer meets an insurer or client requirement
• Corrosion starting at welds and cut ends on an ungalvanised perimeter

Regulation and Compliance in Sydney

Height, position and appearance are the three things most often controlled. In Sydney, the relevant local council sets the local controls over the top of the state provisions, and forward of the building line is where they bite hardest.

Where a job needs approval we say so at quote stage rather than after the deposit. It is one of the few parts of a Sydney project that cannot be fixed later.
