Why this product works
Product details & specifications
Designer Plants' Designer Guard Heavy-Duty Galvanised Anti-Climb Spikes are engineered as one of the most effective perimeter deterrents available for Australian properties. Each 125cm strip mounts to the top of fences and walls to create an immediately visible barrier — sharp, multi-directional sawtooth spikes that prevent handholds and discourage trespassing before any climb attempt is made.
The set ships as 12 strips for a total of 12.5 metres of continuous coverage. Hot-dip galvanised steel offers outstanding corrosion resistance — engineered for coastal salt air, inland heat, and the full range of Australian climate conditions. Pre-drilled mounting holes accept standard screws or bolts onto Colorbond, brick, masonry, rendered, or chain-link surfaces, with no welding or specialist installation tools required.
A 12-strip set of 125cm hot-dip galvanised steel anti-climb fence spikes, delivering 12.5m of perimeter coverage in a single pack.

Where It Is Used
A perimeter topper specified across residential, commercial, industrial, and rural sites where corrosion resistance and visible deterrence matter equally.
Residential homes. Deters burglars and prevents unauthorised access at boundary fence height. The galvanised finish blends with most existing fence materials and weathers gracefully across decades.
Colorbond fence tops. The most popular fence-topper application across Australian residential properties. Pre-drilled fixing pattern aligns with standard Colorbond top profiles.
Brick and masonry walls. Ideal for boundary walls around residential and commercial properties. Anchor bolts secure the strips to brickwork without compromising structural integrity.
Industrial and commercial premises. Warehouses, factories, distribution yards, and depots — where heavy-duty long-term perimeter security is required and aesthetic match to fencing is secondary.
Schools, childcare, and community facilities. Specified by facility managers responsible for after-hours perimeter security, where deterrence value and child-safety positioning (above standard reach height) are both required.
Rural and agricultural properties. Protects equipment yards, machinery storage, and livestock-adjacent areas. Galvanised finish withstands rural exposure and infrequent maintenance cycles.
Installation
Pre-drilled mounting holes are spaced at regular intervals along each 125cm strip. Position 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 coverage. For commercial or industrial installations above 2 metres, consult local council and state security regulations before installation.

Frequently Asked Questions
What surfaces can the galvanised Designer Guard spikes be mounted on?
Compatible with Colorbond fencing, brick walls, masonry walls, rendered concrete, and chain-link fencing. The pre-drilled fixing holes accept standard screws or bolts; substrate-appropriate fixings (masonry anchors, self-tapping screws) should be selected based on the surface.
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 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 many strips are needed to secure a typical fence?
Each 125cm strip covers 1.25 metres. The 12-piece set delivers 12.5 metres of unbroken coverage — sufficient for most residential side or rear boundaries. For longer commercial perimeters, multiple sets run end-to-end. Contact 1800 617 341 for trade pricing on bulk security projects.
How does the galvanised version compare to the black powder-coated version?
Both share identical dimensions, spike profile, and mounting design. The Galvanised finish is hot-dip galvanised silver — clean industrial appearance, particularly well-suited to commercial premises, warehouses, and rural sites. The Black Powder-Coated version matches modern dark Colorbond and contemporary residential aesthetics.
How long does galvanised steel last in Australian outdoor conditions?
Hot-dip galvanising provides decades of corrosion resistance under normal Australian outdoor exposure — including coastal salt-air environments. Surface oxidation may dull the silver finish over time, but structural integrity and security performance remain unchanged.
How are the Designer Guard galvanised spikes shipped?
Ships from the Designer Plants Melbourne warehouse with door-to-door tracking, Australia-wide — including Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Darwin, and all regional and rural locations. For bulk commercial or industrial projects, contact 1800 617 341 to arrange consolidated freight.
What is the warranty on the Designer Guard Galvanised Anti-Climb Spikes?
A 12-month warranty covers material and manufacturing defects. The hot-dip galvanised finish is engineered for long-term Australian outdoor exposure; under normal residential, commercial, and rural use, structural integrity is maintained well beyond the warranty period.
