Security Fencing in Sydney

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.

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 ground conditions that change completely between one side of the basin and the other before pricing the job.

Every security fencing quote we write for Sydney starts on site, with photographs, levels and a walk of the full run. You cannot allow for access constraints that vary from a wide western verge to an inner-west rear lane from a satellite image.

Technical Notes on Security Fencing

We are happy to quote two specifications side by side so you can see what the upgrade actually buys. On reactive shale clay in the west, sandstone and sand through the coast and north the honest recommendation is usually the heavier one.

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.

• Hot dip galvanising after fabrication coats the cut ends and welds, which is where an untreated perimeter fails first.
• 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.
• Palisade top detail is a risk decision, and public-facing boundaries often call for a rounded rather than pointed top.
• Anti-tamper fixings matter only if they are used on the unsecured side, which is where a lot of installations get it wrong.

Choosing a Security Fencing Format

From First Measure to Finished Job

Our sequence on a Sydney job is the same every time: check services, confirm the boundary, set the footings out, cure properly, then build. Skipping the cure is the shortcut that shows up in year three.

Existing survey marks are worth finding before the first hole goes in. A boundary argument costs far more than an hour spent looking, and around Sydney the older subdivisions do not always agree with the plan.

• Anti-tamper fixings throughout
• Sliding and swing vehicle gates
• Palisade fencing with pointed or rounded tops
• 358 anti-climb mesh perimeters
• Welded mesh panel systems
• Hot dip galvanised and powder coated finishes

Working With Sydney Site Conditions

We allow for coastal salt exposure on one side of the city and cracking clay on the other because it drives material selection more than aesthetics do. Specifying around it costs a little more once and saves replacing the job early.

Site conditions here run to everything from flat river plain to steep sandstone escarpment. Levels get set out and recorded before anything is ordered, because a change of grade halfway along a run is a design decision, not something to improvise around.

Because so much of Sydney is the full spread of Sydney housing, from Victorian terrace to new release estate, boundaries and structures tend to have been built within a few years of each other. They also tend to reach the end of their life together.

The Faults We See Most Often in Sydney

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 boundary that no longer meets an insurer or client requirement
• Cut damage through a wide-aperture chainwire mesh
• Corrosion starting at welds and cut ends on an ungalvanised perimeter
