Why this product works
Product details & specifications
Designer Plants' Designer Guard Heavy-Duty Anti-Climb Fence Spikes are engineered as a high-security perimeter topper for residential, commercial, and industrial Australian properties. Each 125cm strip mounts to the top of fences and walls to create an immediately visible deterrent — sawtooth multi-directional spikes with no handholds, finished in a matte black powder coat that complements modern Colorbond fencing and contemporary property styles.
The set ships as 12 strips for a total of 12.5 metres of continuous coverage. Strips run end-to-end across fences and walls of any length, with pre-drilled holes for straightforward screw or bolt installation onto Colorbond, brick, masonry, rendered, or chain-link surfaces. The polyester powder coat is bonded directly to heavy-gauge steel, providing exceptional resistance to rust, UV degradation, and harsh weather across Australian conditions.
A 12-strip set of 125cm black powder-coated anti-climb fence spikes, delivering 12.5m of perimeter coverage in a single pack.

Where It Is Used
A perimeter topper for properties where the security signal needs to be clear, visible, and architecturally consistent.
Black Colorbond fences. A direct colour match for the most popular modern Australian fencing — perimeter security that reads as part of the design rather than added on.
Rendered and painted boundary walls. Sharp visual contrast against light-coloured walls — a clear deterrent without losing the polish of a contemporary residence.
Commercial and retail premises. Professional perimeter security without the razor-wire aesthetic — appropriate for street-facing buildings and customer-fronting properties.
Industrial yards and warehouses. Heavy-duty protection across long fencing runs, with the powder-coat finish keeping the installation looking maintained year after year.
Gated driveways and entryways. Securing access points while preserving kerb appeal — particularly effective at the top of brick or rendered piers and gate posts.
Installation
Pre-drilled mounting holes are spaced at regular intervals along each 125cm strip. Position the strip along the top of the fence or wall, mark fixing points, and secure with screws or bolts appropriate to the substrate. Strips run end-to-end for unbroken perimeter coverage. For commercial or industrial installations above 2 metres, consult local council and state security regulations before installation.

Frequently Asked Questions
Will the black powder coating last in Australian outdoor conditions?
Yes. The matte black finish is a polyester powder coat bonded directly to the steel — significantly more durable than painted finishes. It is UV resistant, weather resistant, and engineered for long-term outdoor exposure across coastal, inland, and tropical Australian climates.
What surfaces can the Designer Guard Anti-Climb Spikes be mounted on?
The pre-drilled mounting holes accept standard screws or bolts on Colorbond fencing, brick walls, masonry walls, rendered concrete, and chain-link fencing. Different substrates may require different fixings — masonry walls typically need plugs or anchor bolts, Colorbond accepts self-tapping screws, and rendered surfaces benefit from masonry anchors behind the render.
How many strips are needed for typical perimeter coverage?
Each strip covers 125cm. The 12-piece set delivers 12.5 metres of continuous coverage — sufficient for most residential rear or side boundaries. For longer runs, multiple sets can be ordered and run end-to-end without gaps. Contact 1800 617 341 for trade pricing on bulk perimeter projects.
How does the black version compare to the galvanised version?
Both versions share identical dimensions, spike profile, and mounting design. The Black is finished in a matte polyester powder coat — best paired with black Colorbond, dark rendered walls, and contemporary residential aesthetics. The Galvanised Silver version is hot-dip galvanised — slightly more industrial in appearance, ideal for commercial premises, warehouses, and rural properties where finish-match to fencing is less critical.
Are anti-climb fence spikes legal in Australia?
Regulations vary by state and council. Most Australian councils permit anti-climb spikes on residential and commercial perimeters at a sufficient height (typically above 1.8m or 2m), with appropriate signage where required. Confirm with the local council before installation, particularly for street-facing or pedestrian-adjacent fencing.
How are the Designer Guard spikes shipped?
Ships from the Designer Plants Melbourne warehouse with door-to-door tracking. Standard delivery is Australia-wide — Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, and all regional and rural locations. For bulk security or commercial projects, contact 1800 617 341 to arrange consolidated freight.
What is the warranty on the Designer Guard Anti-Climb Spikes?
A 12-month warranty covers material and manufacturing defects. The powder-coated finish is engineered for long-term Australian outdoor exposure; under normal residential and commercial use, surface integrity is maintained well beyond the warranty period.
