What are anti-climb fence spikes? Anti-climb fence spikes are rigid steel spike strips fixed along the top of a fence, wall or gate to discourage climbing and unauthorised access. Designer Guard spikes are made from heavy-gauge galvanised steel, come in 125cm strips, and are available in black powder coated or raw galvanised finish. They suit timber, metal and masonry boundaries on residential, strata and commercial properties across Australia.

Choose Your Finish

Both options use the same heavy-gauge galvanised steel strip and spike profile. The difference is the finish: black powder coating for a low-visibility architectural look, or raw galvanised for maximum corrosion economy on industrial sites.

Why Property Owners Fit Designer Guard Fence Spikes

Visible deterrence

A spiked fence top signals that a boundary is protected before anyone attempts to climb it. Deterrence works best when it is obvious.

Steel, not plastic

Heavy-gauge galvanised steel holds its shape and finish in Australian conditions where plastic spike strips fade, warp and snap.

Retrofit friendly

Strips fix to existing timber, metal and masonry fence tops, so a boundary can be upgraded without replacing the fence.

Works with greenery

Pairs with DVG hedge panels and green walls where a boundary needs both privacy screening and a climbing deterrent.

Installation and Compliance

Fit strips along the top rail, capping or wall face using fixings suited to the substrate: screws for timber, masonry anchors for brick and block, or bolts and rivets for steel. Confirm the fence is in sound condition before loading it with any topper product. Wear gloves and eye protection when handling and cutting strips.

Check before you install. Rules for fence toppings vary by state, territory and local council, and some areas require warning signage or height conditions. Confirm requirements with the local council before installation, and obtain body corporate approval on strata properties. This is general information, not legal advice.

Installing on a shared boundary fence usually requires agreement with the neighbouring owner. For commercial sites, position spikes above standard reach height and keep them clear of public footpaths and access ways.

Anti-Climb Fence Spikes: Frequently Asked Questions

Are anti-climb fence spikes legal in Australia?
Fence spikes are generally permitted on private property boundaries in Australia, but requirements differ between states, territories and local councils. Some councils set conditions on height, placement or warning signage. Check with the local council before installing, and obtain body corporate approval on strata properties. This is general information, not legal advice.
How many metres does one pack cover?
Each pack contains 12 strips at 125cm each, covering 15 lineal metres of fence, wall or gate top. Measure the boundary line and round up to the next full pack.
Should I choose black powder coated or galvanised?
Choose black powder coated where the spikes should blend into a residential fence line, gate or dark capping. Choose galvanised where a high-visibility deterrent suits the site, such as commercial yards, depots and chain-link or palisade fencing. Both use the same heavy-gauge galvanised steel strip.
How are the spikes installed?
Strips fix along the fence top using fasteners suited to the material: screws into timber, masonry anchors into brick or block, and bolts or rivets onto steel. Confirm the fence is structurally sound first, and wear gloves and eye protection during installation.
What are Designer Guard fence spikes made from?
Heavy-gauge galvanised steel. The black version adds a powder coat finish over the galvanised base for UV and rust resistance.
Will the spikes rust outdoors?
Both finishes are designed for outdoor exposure. Galvanising provides the corrosion resistance, and the black version adds a UV and rust resistant powder coat on top. Inspect fixings periodically and replace any damaged sections promptly.
Can they be fitted to an existing fence?
Yes. Designer Guard strips are a retrofit product for existing timber, metal and masonry fences, gates and walls, provided the structure is in sound condition and installation is permitted at the property.
Do they work on brick walls and gates?
Yes. Use masonry anchors for brick and block walls, and bolts or rivets for steel gates. The 125cm strips can be cut to length to suit gate tops and wall sections.
Are fence spikes safe around children and pets?
Fence spikes are a security deterrent with sharp points and must be installed out of normal reach, away from play areas, footpaths and access ways. Position them along the top of fences, walls and gates only, keep unused strips stored securely, and handle with gloves.
What warranty and shipping apply?
Designer Guard fence spikes carry a 12-month warranty covering manufacturing faults under normal use, per the DVG warranty policy. Orders ship Australia-wide from Braeside, Victoria, with shipping calculated at checkout. Larger commercial orders may require a freight quote on 1800 960 565.
